5 DAYS TO FIX - electrical gremlins - HELP!!!

Exactly why i said to do the stator check first to eliminate that. Then you move on to other things if all 3 legs are within the service manuals perameters.

Will do tonight, buddy took my damn voltmeter.

To test the stator you set the volt meter on AC VOLTS..simply unplug the 3 leads where they hook into the harness. start he bike and put the NEG into one of the plugs and the the POS into each of the others and run the RPMS up to around 4500 and see what the two legs with the POS lead are putting out. Switch the NEG to the next lead in line and repeat the process till youve move thru all 3 leads.


Record what your getting from all 3 leads and report back.

Charge the battery before starting so theres some power to keep it running when you unplug the stator leads.

I hit up Steve with a few questions and I'll probably be calling him tonight. It's funny, I've completely gone from frame up on this entire bike (bought used and had issues) rebuilt everything but electrical is getting the better of me.


Buddy of mine has my voltmetere (i forgot). So tonight I'm getting it back and going from the stator back and testing everything. I will have everything tested prior to purchasing anything for sure. That much I'm sure of and like most have made that mistake before.

Somethign I told steve.

Low and behold battery that I have WAS new as I thought from Advanced Auto when I bought in March. Took it in to them today and they replaced it for free because it was a 3 year old battery!!!!! SO.... .now I have a perfect and brand new battery. Would that have been the issue to begin with?

Man wish I one of you guys that lives near wilmington, NC to come go through this crap with me.

Don't wanna hijack thread but I have a 78 GS750 that I just recently bought,
It has a new battery, a new Mosfet R/R but the original Stator. I'm still waiting for my Dyna S in the mail,
Do the original stators have a shelf life? I'm in the middle of getting the bike up and going and am wondering if I should replace the original Stator just so I know that everything has been covered for the charging system, including all the bullet connections.

Think of it this way...
The original stator is 36 years old. That's 36 years of being exposed to acids, corrosives, heat, oil, vibration, mechanical shock, and electrical misadventure. That's a lot to ask of the varnish/insulation of the 1970s.
Which is why I'll be replacing mine with new ones, made with 21st century varnish/insulation. I'll get what I can out of the old ones, but I suspect their end will come sooner rather than later, and if left on the shelf, they'll just deteriorate eventually.

I wouldn't count on it being the issue...but it probably wasn't helping.

Test, test, test...

Donot use a MOSFET R/R, see GS Stator in my signature

Yes,but let's hope that the "21st century varnish insulation" was not supplied by the low bidder from you know where! Quality magnet wire ain't cheap!

I can boil down some bones and make my own varnish. Only way to trust it nowadays.

That is the same one ; there are three links in one line that can look like one I guess.

If you aren't signed in, they are same; but if I sign in that link takes me to tkent02 's temp probing. It gets confusing-

Really? that is very strange.


Can anybody else confirm that when you click on GS Stator in my signature that you go to a tkent link instead of this one?

That's a lot of reading! The Mosfet R/R was already installed before I bought the bike. I've read most of the stator pages but in a nutshell, what's the best stator for a 78 GS 750?
