I have a 92 cbr that i have tested with a multi meter. I just replaced the reg. went for about 150 mile. Then i beleive my battery started to make a high pitch noise. Tested the reg when i got home it was pushing way to much around 14-15 volts sitting there. Reved it up the it jumped between 17-19 volts going to the battery. Why i replaced it in the first place was because my original reg. wasn't charging it enough. Now this one is over charger. So now i have a new one, tested that right of the box. pluged it in turned the bike on tested it and seem to be working fine. Then about3 min of test the reg was supper hot. The more i would play with it the higher the volts the reg. would let pass throughbut no madder how high i reved it, it would keep it under 15v. I read the trouble shoot that i had and it said at 2500 rpm it should be at 13.5 volts and at 5000 rpm it should be at 14.5v. Right now at 2500 rpm i am right around 14.3 and at 5000rpm i am at 14.8. So then i tested The + Of the multi meter to the - of the battery then the - of the multi meter to the + of the reg. Said it should have been 0.2volts and it read 0.4v. But i am not sure what to do? Any help, Please?

I am no expert on the electrical system, but have you removed the stator cover and tested how much power the stator is generating...I am thinking maybe it is more than the RR can disipate as heat?!? Other than that I am not sure, 17-19 volts going into the RR seems reasonable, 17-19 coming out is way too high...should be 13.5-14.5...

 

I Have tested the stator and that tested out fine. I think there maybe a wiring issue. NOT sure any els.
