seems to run perfectly once cranked with the exception of the electrical system. when running, all electrical dims or brightens the same as the rpm. it also is not charging the battery once i start it. im new to these macheens so take it easy on me. could this be a voltage regulator?? or somethin else??

It's an easy thing to test so why just bother throwing parts at it and possibly wasting money. Any hot wire on that machine should be under 14 v (not sure on the exact value but around there) when it is revved up so you can test for a regulator with a basic multimeter. Easy spots to test would be accessory plugs, taillight power wire, possibly the gauge backlights, etc.

If the regulator was bad wouldn't you see the voltage up in the 18 v range when the machine is revved up? Maybe the battery is bad and just isn't taking a charge. That would explain the lights brightening up when the machine is revved up. If the regulator was bad all of the light bulbs (and hand warmers if so equipped) would burn out when the throttle is put to the bars.

thx for the quick replies guys.

i tested VDC when off, at idle, and when revved... voltage at the battery post stayed at 12.4 VDC for each condition. i have yet to receive my owners manual in the mail, but from other sources it appears that the charging voltage should be anywhere from 13.2 to 14.4 volts.

oh, and the guy i bought it from just installed the new battery about two weeks ago... evidently throwing parts at the problem without finding the cause first, lol, sorry drake, had to throw that in there tongue.gif

one thing that confuses me though: if im actually not charging this battery, how is it constantly at 12.4 VDC??? ive got the body completely removed now, checked my grounds, wire condition inside looms... everything looks good and clean. (i plan on removing the grounds, scratching with a wire brush, and adding di-electric grease b4 im done)

so ive narrowed my search to these possibilities:

-voltage regulator
-stator
-cdi
-wiring itself

does this sound like ive got all possible bases covered??? or should i include/not include or look for something else completely?

Try checking for the voltage elsewhere in the system, like pierce through one of the taillight wires to check for voltage. It sounds to me like you are just measuring the battery voltage and thats why you aren't seeing the change. Since the lights are responding to engine speed you will definitely see a difference there.

$60 sounds great! my local dealer wants $110 for a regulator.... from some of the research ive done, the electronics on these machines is nowhere near perfect.

im sure you get stuff for cost if you need drake, but where would you guys recommend a regular fella buy these parts??

Try a salvage yard...you'll probably only end up paying around $35 or so. I've bought a good number of parts from salvage yards and have never had a problem. Beats paying 3 times the amount for new parts...

well, apparently the voltage reg and the ignition switch are faulty. the root cause may be the 20 amp breaker i found coming off of the battery. the pouch that it was sealed inside was full of water, and the breaker almost rusted in twain. im guessing with no breaker and conducting through water was enough to fry the regulator and switch. im hoping these are the only two parts in the electrical system that have been damaged....

jeebus cristo!

well, evidently the person who wired the starter solenoid up the last time it was worked on before i got it placed the hot on hte wrong side blink.gif .... wire switched, everything runs perfect.

Good to hear you got it running again. I bet that was a lot cheaper than throwing parts at it. wink.gif Sorry to poke fun but I just have to.
