Charging system issue.

So I just got a 04 raptor 660 and it won’t charge the battery. I get 11.4 volts to the battery. I run it and disconnect the battery and it dies. But if I have it slightly revved up and disconnect it it will stay running. If I disconnect the regulator and disconnect the battery it shuts off no matter what. I’ve tested the stater but got 0 resistance and volts coming out the three white wires. But if I unplug the stater it dies bc the battery dies. I’m so confused right now

It sounds to me like you need a rectifier.

I don’t know if this makes a difference but when revving the voltage basically doesn’t change. And If I unplug the regulator and disconnect the battery it dies so it’s giving some charge

Welcome to the forum!

You need to measure AC voltage (you will see 0 DC) across the three pairings of white wires from the stator.

1- charge the battery with an external charger for at least 24 hours.
2-measure across each of the 3 pairings of three stator white wires DISCONNECTED from the regulator - should be well above 15VAC each when above idle.
3-plug back into regulator - should not drop much in voltage - if it drops a lot the stator may be the problem.
4-if you have 15-20 VAC across the whites when plugged in but the battery remains in the 12V range (not up to at least 13.5VDC when above idle) then the regulator is probably bad.

BTW, the resistance across pairs of whites are a fraction of an Ohm, too low for a normal meter to measure accurately - seeing 0 Ohms or close it on a digital Ohm meter is to be expected.

So. I was an idiot and test the wrong side of the plug. Got plenty of ac volts bc I accidentally used dc last time. That’s what trying to do something in a rush gets ya. But tested the regulator and got .535 , .530 and .490 so I figure it’s the regulator. But guy I got it from is giving me a big bore kit and found out he ran it without oil so the rings are shot and it’d smoked really bad. So earlier today I tore it down to Frame and doing a top end rebuild painting the frame and some other stuff. Thanks for the help!

Good luck with the rebuild!
