I'm the new owner of a 1990 cbr that runs great, looks good, but needs some TLC. The biggest issue it has is the dreaded battery not charging. I have isolated the problem as the stator cover. Of course, new ones are not available from Honda which leaves you with the choice of used or finding someone who can rewind them. I'm coming up with zip for either choice. From my hours of internet research, this seems to be the achilles heel of these bikes. I really don't want to put a 20+ year old stator on...if i ever find one, but there doesn't seem to be another option.

Does anyone who has possibly been down this road before have any advice?

 

What country are you in nedc?

It will help us to help you if you give us more information.

 

I'm in the US-South Carolina to be exact.

 

Are you talking about the Alternator? I guess in 90 honda called it a generator. I don't see why you couldn't find a 1988 cbr100f alternator to put in its place. the motors are almost identical, good chance it would bolt up, looks like they share bolt pattern and shaft. the starter gear is shared between them

 

Alternator, stator, generator... unfortunately the earlier cbr (87, 88) used an air cooled alternator-the 90 on is oil cooled and a completely different design-not interchangeable. I finally found one on the West Coast from a bike with a blown up engine. I'm charging now! Have this thing on the road soon.

 

Is this what yours looks like?



See that black box looking thing? I'm willing to bet that's a diode pack. It's what controls the flow of current out of the winding. Its usually pretty rare for windings to ground out unless they've been mishandled. All those wires are insulated from each other by a thin coating of resin. Its not impossible just improbable. What is likely is that some of the diodes burned out in that pack. It would be a pain but you could possibly have someone tear into it and replace the diodes. Or use a diode pack off a car wired to the windings coming off the stator.

 

Ah cool, good luck!

 

Yes, but that black cover is only there to protect the wires coming out. There are no diodes.

 

I'd like to see the photos of this part. I have a 1990 CBR1000F so it would be good to know just in case......is it the cover, with the windings and such that goes bad?

Thanks in advance,

Warner

 

"is it the cover, with the windings and such that goes bad" Yes, that is the stator.
