Get and use a repair e book !! The subsequent discussions have been copied verbatim from rider messages at the imaginative and prescient forum. They challenge restore or replacement of the stator underneath the left crankcase cover. In short, you should cautiously seal the crankcase cover lower back to the engine or you may have dreaded oil leak. That is especially essential across the stator and spark pickup wires which exit the crankcase cover.
what an awesome charging system seems like engine off on (now not running) engine runnning i established a voltmeter onto my bike to be sure i knew what become going on. There are different methods to reap this. A circuit to mild inexperienced whilst the battery is charging and crimson whilst the battery discharging might be properly. There are industrial model of this to be had for about $40. The voltmeter above is made by way of telex. Its a fab piece because it changed into made for watercraft and so is water-resistant. And... Telex is promoting off this line so if you may discover one on your marine stores they going for approximately $25 now (9/2002). What need to a terrific charging system look like at the vision. Nicely, there it is above. Little over 14 volts whilst walking and the battery desires charging. And except you are doing lengthy rides.... The battery usually wishes charging. Click on for the massive image what goes terrible and why charging systems have usual disasters, and some more common than others relying on how well built they may be. Right here are the commonplace failures. Stator winding failure one of these 3 wires inside the stator as broken internally or (worse) has shorted to the engine and ground. That is maximum traditional because the stator is uncovered to quite a few warmth and vibration within the engine. Cord insulation additionally decays over the years. Ultimately, if the regulator fails or the current draw from the bike is just too remarkable (bad battery or horrific corroded connections) the stator wiring and connections can begin to soften over time. You may see melted plugs and scorched stator bodies when this takes place. Lost stages will decrease ac (and dc) output. And/or shorted wires can fry the stator and regulator too. Rectifier failure the rectifier uses 6 diodes organized to "chop" the ac output from the stator to dc modern-day. The dc is conditioned a touch bit more with capacitors, and so forth... Considering that "rectified" ac remains a little "uneven" and not precise for newer liquid crystal display microchip driven shows and other solid state devices. Needless to mention, if the diodes burn out you have got issues. Depending which diodes move the dc voltage output may be decrease to nonexistent (0). Regulator failure much less likely but feasible is that regulator circuitry fails and the output may be too little or an excessive amount of. Too little and the battery subsequently dies. Too much and the battery will overheat, bubble over and self-destruct. Warmness disappation there may be a selection of debate about the stator and/or rectifier overheating and failing: the stator is cooled via the oil below the crankcase. If the oil is allowed to get low then the stator can doubtlessly overheat and fail. The rectifier does no longer rate the battery all the time. If the battery is complete up then the rectifier will "shunt" the electric pulse from the stator back to ground. In laymans phrases ... "Shunt" basically approach the white wires are grounded. The stator pulse goes nowhere. This isn't always precisely what's happenning however close (don't ground the white wires!). While this happens the electronics inside the rectifier are coping with the excess power and matters get hot. That is why it has warmth fins on it. What do i believe ??? hiya.. When you consider that i wrote this i get editorial license ==>> i for my part agree with maximum anyone's charging troubles stem from both a bad battery, low oil or most significantly horrific connections on the motorbike. Any bad connection at the bike set off voltage drops acroos the charging circuit that overheat each element in it. It'll melt the white 3-twine stator connector (very standard), and ultimately overheat the stator and rectifier. A terrible battery will overtax the charging circuit and soften it. Not unusual scenarios horrific connections inside the charging device wiring reasons a "voltage drop" throughout the wiring. This in turn reasons an boom in current draw from the generator. The greater strength going to terrible connection is transformed to heat. The heat produced in either the stator or rectifier causes a failure. You would possibly see the symptoms of melted plugs and wires or warmness deformation on stator or rectifier bodies. The battery itself is causing the heavy present day draw cited above. This could be a bad battery -or- a tired battery which you are charging with the bike charging machine. Humans regularly associate charging device screw ups with "leaping" a battery. Its not the bounce that did it most probable (except you hook the cables up backwards which immediately fries the rectifier commonly). The trouble is that your motorbike charging system isn't always heavy obligation sufficient to rate a lifeless or horrific battery. Crappy components. The reality is the vision stator is affordably constructed. The stator wiring fails. Also, each the stator and regulator can be cooled higher for sturdiness. Any way you study it the system has a tendency to fail in advance. Myths these are some myths concerning charging structures and here are a pair: "jumping starting will harm your gadget" achieved efficiently .... Untrue. If you bounce a useless battery that isn't appropriate (will now not keep a fee) the charging system can also convey a heavier load for longer than it changed into designed for. Recall the vision system is "rated" in a great world for 20amps ... But not for the subsequent 2 hours. Upload to that a few terrible connections, headlights, the stereo and a/c (i am kidding here), and .... You get my point. You may overheat and in the end fry a few part of the device (stators , regulator, both...). In case you bounce the battery with the cables reversed you may also cream the gadget (maximum in all likelihood the regulator). "Disconnect one of the three stator circuit wires will assist the stator run cooler and remaining longer because there is much less unused electricity flowing via the machine" this genuinely sounds accurate in idea. No, virtually. However...... Unfaithful. Do not take my word for it. Name any knowledgeable save inside the world please. And, genuinely, if this had been true this method might be used on each generator within the international and pretty virtually it isn't always, so_ooooo..... "Magnets never go terrible" . Magnetism is a nebulous factor (how regularly do you get to apply that word) and from grade college science you need to remember that iron magnets tend to lose energy with vibration and warmth. In which are those stator magnets again? How frequently is this a trouble. Uncommon. Approximately as rare as a spark coil going horrific. However, it's miles possible and should now not be completely neglected of your wondering. I had an alternator rewound twice for a vehicle that in no way pretty placed out a exquisite stable voltage whilst loaded as much as its rated amp output. What's left that may be wrong? Crappy magnets. Don't forget in a motorcycle (unlike an all-components-in-one alternator) your charging parts (stator, magnets, regulator) are all separate portions. Preventive measures for the yamaha imaginative and prescient charging device except you purchase and installation a newer aftermarket stator and regulator (see go with rex hyperlink underneath) you can't make it a "higher" device. So, the trick is to make what you have got bullet proof. Right here are the tricks encouraged via others lifted verbatim from the vision discussion board documents. Make all connections inside the charging system smooth and protected. Solder wires to their reputable plug pin ends. Use wd-40. Use dielectric grease on the outdoor to "water-evidence" connectors. Qbs using plain easy not unusual wheel bearing grease, placed a mild coating of grease inside the inner areas of the stator coil connector. An excellent better everlasting fix might be to clip off the male and lady components of the connector and tough wire/solder the connections. The wires are white in color on each facets of the connection so it is now not vital which ones are soldered collectively as long as a bike wiring harness wire is attached to a stator twine. If for a few motive this connection desires to be broken in the future, truely cut the soldered wires and then resolder them upon reassembly. Electric system operation: the v alternator places out one hundred of its ability ability all of the time, given the rpm it's far working at. What the motorcycle load does not use is shunted to ground with the aid of the regulator. The connector carries some thing amps the alternator is placing out all of the time regardless of bike load. Low rpm = low amp output = low amps passing through connector= electric desires deficiency made up by using battery. High rpm=max amp output=max amps passing via connector=amperage left over after motorcycle load is serviced is shunted to ground. Word that is both instances all amps skip via the connector before any electric distribution or alteration is accomplished. The alternator constantly places out the most it could no matter what's happening down move. Consequently, the connector is usually passing (or trying to pass) the max amps to be had. The way the hassle develops: whilst the connector is rendered inefficient because of corrosion the alternator maintains to place out all of the amperage it could. It doesn't know or care approximately the situation of any of the electrical components that comply with after it. It simply stays busy doing its thing. However, for the reason that connector is no longer able to skip thru a hundred of the power going into it, it passes what it could and the rest of the power backs up in locations and defaults into warmth at each places. One place is the connector itself and the opposite is the alternator stator coil. The heat in the connector melts the connector plastic which turns all gunky and greasy and nasty and usually adds to the connectors' ineffeincy which in flip compounds the hassle. The heat in the stator coil melts the coils' insulation which ultimately fails and permits the strength the coil creates to go to ground thru the engine cowl that the coil mounts on. This is why the check for a failed coiled seems for continuity between any individual of the stators' three coils (accessed through the 3 white output wires within the stator facet of the connector) and floor (the engine). Continuity indicating a failed stator coil. Don't forget to thrill now not loose tune of wherein the trouble originated, specifically corrosion in the stator connector. The large clue right here is the condition of the connector. A melted nasty connector were given that manner from warmness. Wherein did the warmth come from, internal or outdoor the connector? If inner, what was the supply? The manner i see it you've got alternatives. 1. Clip off the lady and male halves of the connector after which solder each former lady twine to a former male twine. Of direction, each resulting soldered joint should be personally insulated. It would not matter which former men are soldered to which former ladies. All of the wires on every aspect of the relationship are white. This what i have finished and it has served me thoroughly for the last six years even below severe heat and cargo(a hundred thirty/a hundred watt headlight bulb)situations. The simplest standard cause to apply the connector is update the stator coil. That hassle is now constant and the facet left engine aspect cover should not want elimination for a completely long term. While that time comes, certainly clip the soldered connections after which resolder them upon reassembly. 2. In case you are paranoid approximately clipping off the connector and it is nevertheless serviceable, easy the connector pins and sockets to bright and bright condition after which practice a skinny movie of common non metallic wheel bearing grease to all steel connector surfaces. Then reconnect as regular. This method bureaucracy a vapor barrier that maintains air borne water away from the connector metal, thereby inhibiting corrosion formation. Make sure you've got and hold a great battery. You can use a multi meter to degree the amp draw on the battery after starting. With lighting fixtures off it should not be extra than about five amps (if that). Much more and you've a few problem happening there. "The stator rotor is lined. Truly don't harm it with steel wool. It produces an electrical subject with the stator, and must be left alone. " Restore and protection of the yamaha imaginative and prescient charging device get and use a repair e-book !! The following discussions were copied verbatim from rider messages at the vision forum. They concern repair or replacement of the stator under the left crankcase cowl. In short, you ought to carefully seal the crankcase cover back to the engine or you'll have dreaded oil leak. That is specially essential across the stator and spark pickup wires which go out the crankcase cowl. Stator wires exiting crankcase cowl pictured on left. Yamabond #four via dan else(along with permatex#2) is quite love it as far as tenacity is concerned. 2) take left cover off again, clean all vintage goo out very well. Three) using quality sandpaper, smooth carefully all aluminum surfaces that the grommets are available bright bright and easy. Wires. The wires inside and out of the holes a chunk to ensure the sealants coating the holes. 6) wait approximately ten mins for the yamabond to set up a chunk. Area a new gasket onto the left aspect of engine case, and re-gather. Eight) wait 12 hrs if you can before refilling with oil to ensure the stuff units up well. No leaks so far in doing this twice this manner after four preceding tries to remedy same leak. Rate healing procedures by means of bernard lajoie pos.&Ground cables,these are liable to fail. Elimination suggestions by way of qbs regarding elimination of the three phillips head screws (and for that count number, all phillips head screws in popular) that connect the stator coil to the left engine cowl: if you do not have an effect screw motive force with a well sized bit, don't touch them till you do. Particular to the v: after the left engine cover is off, lay it on its' side, outdoor down, on a wood surface. Then use the impact driving force and hammer to loosen the 3 screws. Reattchment with the effect motive force is the reverse, being carefull to not over tighten the the screws. First tighten the screws as tight as you can by way of hand. Then deliver them one or (max!) Impact driver blows. Who it is probably that can need to do away with them within the destiny. Another tip: if you haven't got an impact driver, or the screw heads are too trashed to be of any use, but you do have a little room to work with around the screw head vicinity: use the smallest vise grips you may get and grasp the screw head very firmly and strive to show the screw head in a counter clockwise route. I have used this approach typically over the years and never fail to get a small thrill of delight everytime i overcome the challange of a screw head that at one time would have prompted me hours of frustration and grief. Another tip: if you don't have an effect motive force, you may simulate one the use of a screw driving force and a hammer. Insert the end of the screw motive force into the screw head, firmly draw close the screw driver take care of and preload the screw within the desired direction of screw rotation, then hit the top of the screw driving force with a stout hammer blow. This approach can be used for both direction of screw rotation. Every other tip: a broken screw head, bolt head, or nut can occasionally be loosened by way of using a sharply pointed punch and hammer to rotate it in the desired course. It is time with the aid of qbs it's time to reattach your starter snatch. Get a haynes guide. Take away your stator rotor/flywheel. Do away with the 3 allen screws that attach the sc to the again of the rotor. Look at the grasp rollers for flat spots and replace all broken rollers. Check out the snatch housing for cracks in the curler location. Update or restore(weld cracks) housing as necessary. Reassemble and reinstall sc. Whilst attaching sc to back of rotor, use new allen screws that protrude 2 or three threads past the inside floor of the rotor. Use loc-tite on those screws and between the very easy oil loose mating surfaces of the sc and rotor. After the screws are tightened, pean their protruding threads. Reinstall the rotor sc meeting. If the future ever calls for removal of the sc, grind the peaned threads stage with the surface of the rotor and unscrew them as common. Earlier than final meeting of the left engine cowl, do a continuity take a look at of the stator coil as defined in the haynes manual. If continuety is determined, replace the stator coil. Whilst reassembling the left engine cowl, inspect the stator coil connector for corrosion associated inner heating damage. If determined, critically recall clipping off the connector and hard wiring (soldering) the relationship. If the connector continues to be servicable, at the very least you must lightly grease the internal of the connector. In case you don't, stator coil substitute truly lies to your destiny. If the above sc attachment and stator coil connector processes are accomplished, the left engine cover ought to now not require removal for decades, if ever once more. Once you reattach your sc you may be surprised at how quite the engine is at idle. Your information concerning v engine life is accurate. A properly maintained v have to pass at least 100k with out a foremost internal problems. Mine is working on 73k. Flywheel removal via pat sullivan i recently eliminated my flywheel to investigate the starter clutch. I used an effect wrench, and with it i did now not ought to hold the flywheel in any respect. I checked with the neighborhood yamaha save in santa clara, ca and that they indicated that they use pullers for car harmonic balancers that they get from local suppliers. I bought this sort of for round $30 and it worked great. Later i found out that you can rent those at numerous tool supply rental houses. As indicated earlier in this forum, you need to whack the bolt at the puller quite difficult similarly to the usage of the impact wrench. I thought for a while i wasn't going to get it off, but in the end it popped off once i hit it. Placed a padded box underneath the flywheel even as you're doing this to catch the flywheel and the starter clutch rollers and comes which might be in all likelihood pop out while the flywheel subsequently comes off. You'll probable also want a effect socket to do that. I split my everyday socket on the primary strive. Took stator flywheel off on december of closing 12 months because i had to change the roller pins and get the bottom where the ones pins go to welded again because it became cracked. That is how i did: o eliminate left cover o placed the suitable length socket wrench at the flyhweel nut (a.Okay.A massive nut even though right now i do not don't forget if it became a nut or a bolt. Who cares? =) O get a bolt like 2-some thing inches lengthy (a.K.A. Small bolt) and then flip the flywheel (using the wrench on the massive nut) until you can jam the bolt between the bike body and people holes that have been drilled at the outside of the flywheel for balancing. The idea is to use the small bolt to prevent the flywheel from turning even as you play with the massive nut. O keeping the small bolt, so it will no longer come out whilst there may be no compression load on it, unfastened the big nut o using an good enough puller, take the flywheel off. What i used changed into a a three-bolt puller like the ones used to, say, pull steering wheels off (some thing that may be determined at your pleasant autozone or comparable store). Now, the 3 bolts in which the incorrect size and pitch for my want, so i went to a hardware store that focuses on nuts and bolts and were given three bolts (allen, now not that it matters) that might healthy at the thread and could be lengthy sufficient in order that they could be within the puller after i threaded them into the 3 flywheel holes. So, their duration honestly relies upon at the puller you're the usage of. When you are equipped to position the bugger again, do do not forget to align the flywheel as there's a key/notch association among flywheel and the conical base wherein the bit nut is bolted to. Besides that, use the small bolt to keep the flywheel in vicinity as you tighten it and also you have to be home unfastened. Misc discussions voltmeter? Voltmeter by using burke storti has any body discovered how to deploy a volt meter or different indicator that could tell the situation of your charging gadget while the motorcycle is being ridden? With this, as a minimum we might have some caution that the stator is "pushing up daisies". I had a comparable enjoy as dan. I got here domestic from a 150 mile experience to discover my battery was lifeless once i killed the motor in front of my residence & could not get it to begin. I have a voltmeter, and a few feedback on what it indicates by means of john logan i installed a voltmeter, a clock, and an oil strain gauge across the dashboard inside my 'eighty three's fairing. I glued a hardboard backing to the skinny plastic dash for greater assist. The gauges i selected had been the "cockpit" series from vdo. They suit the vision's devices, besides that they've blaze orange in place of yellow needles. They have held up perfectly for many years. It's a totally quite setup. The wiring for a voltmeter could not be easier: you just need a warm twine and a ground. One component i've observed is that the voltage has a tendency to differ in mysterious methods, even when the stator and regulator are new. Revving the engine produces a drop in voltage over sure rpm degrees, even though there's sufficient voltage at idle. I additionally have an indicator led on my tdm 850 that glows inexperienced, yellow or purple relying on the voltage. This too shows abnormal voltage drops in the course of elements of the rpm variety. Website online, i systematically added the resistances and voltage drops within the imaginative and prescient charging circuit inside specifications. This helped however did now not absolutely put off the strange voltage dips with engine rpm i have usually visible with the voltmeter. The voltmeter is a extraordinary assist whilst the stator is failing, because it gives the warning you need to avoid getting stranded. The rest of the time it have to no longer be too carefully examined. Normal voltage take a look at query by qbs thank you for an outstanding gauge piece. Could one get the equal benefit of coming near near stator doom caution by way of doing a multi meter voltage test across the battery terminals earlier than the primary journey of the day at say 3500 rpm and preserve a intellectual note of the reading for destiny comparison., Form of like checking the oil. Battery get admission to may be very clean. I realise this a truly of a nuisance and might not display problems which can appear later in the day, but stators do not appear to fail catastaphically. As a substitute, they sort of sneak away and earlier than you are aware of it they're gone. Makes experience to me with the aid of john logan i suppose your system makes sense, however it would be more than i could ever force myself to do automatically. For the 'eighty three, a voltmeter within the dash is reasonably-priced and smooth. Some fee properly under $20. For the 'eighty two, i'd advise the led kind -- it's only a little button with a sparkling bulb in it, and ought to be smooth to find a spot for. You want more than one inches of clear space below the mounting hollow. Stators cooling stators cooling via mark moreland just discovered this website. Study some dozen messages but did not see a suggestion on stator cooling. I was an rev member approximately 1990. I acquired numerous years newsletters. One had a tech tip that advised including an oil spray orifice to the bolt in the oil gallery of the stator cease of the crankshaft. I don't forget the orifice changed into drilled at ~.040" dial, and turned into counter bored larger to assist cut up a stream and make the oil sling outwards to the stator. Does all of us bear in mind this? Purple: stator cooling by way of chris arrowroot i have seen that repair too, but i cannot trust spraying warm oil at the stator might enhance its situation. Oil cooled stators with the aid of dale the imaginative and prescient's stator is already oil cooled, however the waft is simply too confined or now not even, resulting inside the over heating at excessive ramps. Growing the oil drift could help however i haven't any idea as to a way to make sure that it is flowing (in and lower back out). Viable source for this stator cooling tip with the aid of john logan i do no longer recognise whether drilling the rotor bolt facilitates the stator durability hassle, however i've a clipping from the march, 1984, issue of rider mag discussing a comparable restoration for the venture, which could be very much like a four-cylinder version of the vision: "one of the most important problems recounted with the aid of yamaha has been stator failure. The alternator has been jogging in an inadequate oil bath, which has induced the stator wires to overheat and short out. Ours failed at 11,500 miles. Most were giving up at across the 8000- to 10,000-mile mark. To be able to decrease the working temperature and increase the reliability of the ac generator, an advanced rotor bolt with a zero.7 mm [0.0276 inch -- jab] oil passage must be set up. This components extra oil to the generator vicinity to chill the rotor and stator. An improved [venture] stator has been designed for 'eighty four." I would be fascinated to understand if all people has revel in with this form of fix for the imaginative and prescient or has examined the progressed rotor bolt for the '83 venture. If the latter simply has a bore via its center, that should be easy to accomplish. Be aware that the article's bore is smaller than the value mark gave. I would be worried approximately consequences on oil pressure -- does all and sundry have records approximately this? Response via jason morris 'll need to have your bolt drilled at a machine save or do it your self with a cobalt or titanium drill bit on a drill press. Repair the hassle via jeff swan the hassle with the stators is the excess heat created by means of the corrosion on the connections. The drilled stator bolt was a stop gap measure by way of yamaha whilst stators started out burning up. I wager they thought they needed greater cooling whilst the hassle changed into the relationship and that they knew they couldn't get everybody to clean the connections. I did this mod to my imaginative and prescient, but that hole is welded up now as i have become better knowledgeable. I don't feel it'll preserve your stator from burning up however will postpone the inevitable. I say keep the oil wherein it is able to do it is task ( inside the foremost and rod bearings) and attach those connections. Use a few artificial oil for cooler running oil tamps if not anything else. Battery trivia cranking amps: cranking amps is the spec that tells you ways an awful lot cutting-edge a battery can produce for 30 seconds at a temperature of 32° f and no longer have the voltage on any of the man or woman cells drop under 1.2 volts (7.2 volts for a 6 cellular automobile battery). This could also be called mca or marine cranking amps. Bloodless cranking amps: that is the identical test as cranking amps however is accomplished at 0° f. The cca spec is especially vital if you live in a honestly cold climate. For the reason that chemical response that produces electrical modern-day inside the battery slows down as the temperature drops, the battery can produce much less cutting-edge at less warm temperatures (specifically beneath freezing). Whilst comparing the modern-day ability of batteries, make sure that you have a few standards to qualify the contemporary ratings. In case you see the cutting-edge score with out ca or cca, you don't know how the battery was tested and the cutting-edge rating is without a doubt vain. Reserve ability: the reserve capacity is the time that a battery can produce 25 amps at 80° f before the character cell voltage drops underneath 1.75 volts (10.5 volts for a 6 cell car battery). Deep cycle vs preferred battery: a everyday lead-acid battery might be damaged if it is completely tired (even though it's simplest one time). A deep cycle battery is designed to live to tell the tale being tired more than one instances. Deep cycle batteries have more reserve capability but have much less cranking amps for a given size. A fashionable battery could have greater overall floor area on its plates when in comparison to a deep cycle battery of equal length. This extra floor area gives greater place for the chemical response to take region and consequently produce a higher output present day. . They may be the motorcycle stator guru's. They bring new stators for the whole lot including the imaginative and prescient at approximately $one hundred twenty five.00us and feature a full one year warranty.
