    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Caltric Stator-no coating on stator windings?

So the stator does need a coating of this substance on it?

If so awesome! I think this may have just solved my charging issues. I didn't even think about it when I put my new stator in. I also bought the lower cost stator. It had good ratings and was comparable to the other stators I could find if not the exact same. It didn't have the coating so it is shorting and is not charging my bike. You guys are great! I have been stumped on this for a while...
 
If you r3move and decrease with alcohol you might be able to revarnish it. You need to make it dry and clean. I opted for another with epoxy coating, electrosport.

A caltric stator failed in my 650 because the lacquer came off the windings. The oil shorted it. I measured the resistance with it dry on the bench and when I poured oil on it a short developed.

Just to be clear, you measured resistance with a VOM? What was the resistance range if you recall?
 
Huh? Motor oil is a good insulator.

This bench test is really odd but I'd expect it to be the weight of the oil making the short connect...the worn unvarnished crossed wires would be very nearly touching or touching in any case. Maybe the heat of the short might burn the oil leaving carbon and more as a buildup to conduct...?

Perhaps another example of CCC; Confusing Correlation and Causation.
 
Well that's how it behaved. The insulation was not sticking to the windings, probably due to poor prep on the wire or the lacquer was thin.
 
Oh! for sure ! It seems an oddity is all so it invites speculation. I've tried to cut up old ones to find shorts as a curiousity but It's too crude to really see much beyond guessing.

I would speculate that principles of physics is still involved :)
