Hey all. I know this has been done to death. But I've got an 85 Aspencade, that just wont charge. To keep this short and sweet, I've put in a new battery (the other was about two years old), it's had the the stator wire fix done (not by me, but done), ithad thestator replaced about 15K miles ago (the gasket on the stator cover looks like a recent replacement). I've been checking the wiring.When i got to the voltage regulator,I noticed the connector was plugged at a bit of an angle and theend with the red wires was burnt (as if from arcing). Before i juststart throwing parts at the problem. What's the likelyhoodtheregulators toast?

I appreciate any suggestions.

thanks again

your gonna have to do the stator checks, looking for around 70v AC across pr's from the 3 alternator wires, (plug disconnected) and check no ccts to ground on any of those 3 wires also. Just because it's had a new stator, you can't assume it hasn't failed again- hence the popularity of the external alternator conversion. Any wires suspect in the area you say can also give problems, as can the regulator- but I'd check the stator first..Steve

Is there a place i can check the stator wires, if they've been soldered. Can I check them while there connected to the rest of the system, or do I need to cut them to test?

They need to be cut. You could disconnect the connection at the rectifier to avoid desoldering the joints.....Steve

thanks Steve, I'll check'em tonight. I sure hope it's not the stator.

If it is your stator I would consider the conversion. I bought my wing on July 3rd and it quit charging on July 5th. I did the conversion and LOVE it. If you use new alt your looking at approx $500. It's not an easy task, but if I can do it anyone can. I'm showing over 13 volts at idle. Hope stator checks out OK. Also if you haven't done so replace dogbone fuse with blade type.

I'd certainly fix those burnt plugs before I called the system dead. That may be the whole problem.

If your stator was replaced with an OEM unit, the newer ones are pretty tough. If it's aftermarket...well.

I just finished today replacing the starter relay, and the voltage regulator on the 2nd 85 ltd and now the system at 1200 rpms, is showing 14.5-6 at the battery, will stay there until, whereas before the new stuff, it would start off at 13.5 and after 5-7 minutes drop to 12.8, and continue down, this is the second 85 ltd that I have done this process with and I am convinced that voltage regulators are as big a culprit as any of the other issues. I did spend $113.00 for the v/r, and $40.00 FOR THE TWO PARTS, PLUS THE SOLDERING and the clean up , but if that will prolong the stator so what.

thanks for all the input. The alternator option is definately on the table. But I'm going to give it a good going over, first. I replaced the burnt connector, but havn't checked the stator yet. I did notice over the last month or so. voltage running higher than normal, arounf 16v. I just thought it was my battery going bad, guess not.Anyway, DVM across the battery shows about 12.5v, revved to 3100rpm, gets close to 13v. I'll report back as i find out more info.

thanks again, and keep any advice coming.

tomslyk, The stator will show some charge if faulty as long as the lights are off. The 16v problem possibly points to a regulator issue or the bad connections to it. Good luck....Steve

well i finally got around to checking the stator. I cut the wires to be sure it was isolated. looks like its got a dead leg, dangit. so now begs the question. do i pull the engine, and replace the stator or, alternator conversion kit. sound like a full weekend project either way.

question? What's the physical size of the geo alternators? I've got a practically new alternator on my sons maxima, onwhich he shelled the transaxle. Is this a viable donor? As it would cut down my costs considerably.

also, I used to be a parts mgr, at my local John Deere dealership. I'm assuming if i do the conversion size matters in the amount of alteration to the fairing, fan/radiator palcement, etc.. Some of the equipment alternators aren't much bigger than the pulleys that are on them, that is to say small, and produce a regulated 12v @ 40amps. Any thoughts?

I imagine 40 amps is more than the original stator and as the unit is small then that would simplify installation...Steve
