'04 Wing, multiple alternator failures

Postby bob-c » Wed Jun 24, 2015 10:33 pm



I'm working on a friends GL1800. It has now had 4 alternators fail within 2500 miles. Upon disassembly, it has been broken wires in the armature. This latest one was a new alternator with about 1800 miles on it. A wire broke, flung out and contacted the stationary and promptly killed the voltage regulator as well. Each has been the same. Any ideas anyone ?

Sounds like a bad batch of alternators, are these OEM or aftermarket units that are failing?
Can you get Compufire alternators in Canada? I ask you this because they have an upgrade unit for the GL1800.

Four within 2500 miles is insane. I'd start looking for a common cause.

First off I would try a different regulator, from a different manufacturer, to rule out a bad batch - and my recommendation would also be a Compufire.

I'd also check for unusual vibration once installed, that might be causing the problem. Have you also changed the alternator damper?

Thanks for the Compufire suggestion. That is certainly worth a try. As for the Alternator Damper, there is no indication of a problem in that area...no unusual noises or vibrations and no excessive oil seepage from the output splines/seal when the alternator is first removed. It really could be just a bad batch of alternators...but it's getting expensive and annoying.

No warranty on any of them?

I would change parts sources fast.

Were any of the 'new' alternators a Honda OEM alternator for the 1800?

CompuFire has had mixed reviews in the past couple of years.
Enough so, that I will NOT be buying one ever.

All that said though, I did a poll a couple months ago on 1800 alternator failures and the results were almost nil. Enough so, that I canceled my plans to carry a spare one on my big trip this summer.
That and my bike has 98,000 miles on it. (lord don't jinx me for this statement)

There were no markings on any of the replacement alternators, leading one to believe they were not OEM. The last one was a Mitsubishi. Your bike has 98K on it, the bike I'm working on with the problem has 68K on it and my own has 125K on it (Touch wood, no problems with mine).
Compu-fire could not answer direct questions, so no, I wouldn't buy one of them either.

Are these units brand new or rebuilt?

I think they were new, but they had no numbers or markings on them to indicate their origin. This next one will be from Honda so we'll see if it has markings of any kind. I'll get it tomorrow.

The latest alternator is an OEM. It is quite different from each of the previous alternators, indicating that all previous ones were aftermarket. The new one is about 1 lb heavier, has a better finish on it and has a Honda sticker shellacced to it. It now has 1500 miles on it and, touch wood, is still going. Maybe it was just a really bad batch of alternators. Thanks everyone.
