    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...

    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.

This is driving me nuts...
From a brand new battery that reads 12.7V cold, a replaced stator, and replaced R/R (both used), I still have absolutely NO increase in voltage while the bike is running, either at idle or 5000 rpms.

The voltage reads about 12.00 - 12.01 while it's running (that's an improvement since I replaced the RR and stator) which jumps up to 12.12 or so when I take out the signal light fuse (is that significant or just common sense?).

When I measure resistance across the 3 leads from the stator, I get a nice consistent 1.4ohm, just like it says you should in the stator papers - but when the bike is running, when I should be getting 80V AC acrsoss the pairs of leads, I'm only reading 2-3?!?!

I bypassed the wiring harness by connecting the 3 leads from the stator directly to the R/R plug, but that doesn't seem to have made any difference...

I love my GS but I'm ready to go JP (justifiably postal). Can anyone shed some light?

if your not getting the ac volts at the stator then you still have a bad stator. used electrics are a bad deal in most cases!
 
Yup, the stator is poo.

My condolences.

If the R/R is from the same donor bike, it's probably also poo, but do the diode checks to see.

It's up to you whether Electrex is too expensive or you want to try again with used parts.
 
Re: More Charging Woes

Well Yes. You replaced a faulty stator and R/R with a faulty stator and R/R.
Sometimes, you get a little "free" milage by going with used electricals, but the downside is when they do die, youre usually 60 miles out in the country at 2 am. I would replace them both with new parts. Electrex isnt cheap, but I dont like hiking through 60 miles of cornfields in the dark either.

Measure the stator wires to ground you should get an open/no reading
if you get a reading you may have pinched a wire when installing the stator cover Like I did :oops: It's hard working in the dark :roll:
 
Thanks for all the replies - don't worry, I know what I'm getting into with used electricals...! Thing is, I figured I had a good stator when I got those nice consistent resistance readings across the pairs of leads.

So I should get no reading btwn each stator wire and ground? I'll try that one.

Speaking of grounds, I measured resistance btwn my battery -ve terminal and a bare spot on the frame and got zero. Well, 0.7 but pretty close to zero. Is that the right way to check that the ground is okay, and in this case, does that sound okay?
 
It depends on your meter, it should be fine. Disconnect the stator wires and recheck the AC voltage between the wires Not from ground
