Regulator and Charging

[Guest]

So, I know I have a charging problem as the battery is only getting 13v at 4000rpms. I've performed the initial "passive resistance or continuity tests" and everything seems fine. Then I tested the regulator via the service manual instructions (see attachment) and I get no readings on my meter. So, I'm assuming the regulator is bad.

Now for my question, "Would a bad regulator possibly limit the voltage to the battery?". That would explain the 13v max going to the battery.

Can anyone recommend some good replacements (regulators) for my '81 GS650G?

Thanks again.

Shendingen are good, there are some series rectifier/regulators out now that are much more efficient. One series rectfier/regulator from some Polaris snowmobile model goes really cheap on ebay.

There is a lot of info in a lot of different threads about this.

Do a quick test

Lots of posts on charging problems. Yeah, a bad R/R could limit voltage, but so could other things, so it's best to pinpoint the problem- no sense putting on new R/R and still have a problem.
I just put a series style SH 775 on my 650 - for the $65 price, I think this is the best way to go,BUT your stator and wiring must be OK or the R/R won't work right, so do some testing.
