Road_Clam, Thanks for that thread, I will definitely run that test and give you guys an update today!

[DieHardBigRaw]

ok, some quick tests done at lunch today on the battery. I tested the battery with key out of the ignition at 13.2V, with the key in the ignition and turned to run (but not started) at 12.5V and finally with the engine running and revved to appx 4-5000 RPMS at 12.1V - 12.3V. So it appears that I have a charging system issue, as I suspected a long time ago. Since motorcycles dont have alternators, I am guessing its either the stator or regulator. I will do my best to check those and get back to you guys. I am NOT well versed on electronics so it may took few tries to get some accurate readings. Thanks guys, and I hope to have another update for you all in a few hours!

It really looks my situation is similar, DieHard, you explained your incidents with loss of throttle, like I should... Keep us posted what have you discovered...

Stop right there..........Oh yes they do!!!!! You obviously haven't read the manual. Most modern vehicles have an alternator, simply because it's the most efficient method of producing electricity. Rectifiers then convert it to single phase dc, with a regulator to maintain the charging voltage. As you haven't read the manual, I'm enclosing some drawings.

Alantf to the rescue. What would we do without a retired electrician on the forum? Not knocking the rest of the guys but an electrical guru is a real bonus.

Here is a picture of the multimeter I have, which setting do I need to use to test the regulator/rectifier? I drew an arrow to the one I tried, but nothing showed on the screen. Thanks guys, electrical is defintely not my thing, not even close! :??:

It's easier and more conclusive if you test the stator like I suggested, for that test set you meter to DCV 250

[DieHardBigRaw]

yeah, sorry, stator, so much reading, everything is running together, thanks for the clarification. and I have DCV 200 and DCV 500, is either ok? Thanks

NO. NO!!!
Check the output of the stator with the meter set for AC voltage!
The output of the rectifier is checked using DC voltage!
A good stator should put out AT LEAST 60 VAC.
Set your meter at 200 or 250 VAC to test this.
And the bike must be running!
Remember to test between ALL THREE leads.
Also check the stator for grounds. It is covered in the manual.
For this test, make sure the bike is NOT running!!!

The output of the rectifier should be at least 12.3 volts DC.
If the RPMs are at about 3000 or higher, you voltage
can go up to over 13.7 volts DC.
Set your meter at (can't see your pic now) 20 volts DC.
As you were told before, read the manual!!!
I have those pages burned into my memory...

OK I need further explanation. To have AC you first need INPUT voltage, then the inputted voltage is transformed to varying output voltage. A stator only has output voltage therefore it's considered DC ? Do I have this comment incorrect ? I'm no expert on the specifics of AC to DC conversions on a charge system so get me on the same page as you :2tup:
