gs650e Stator + R/R issue

[Mrtoto]

Wire your system like this, and test again. Be sure to bypass the factory wiring, other than the red wire feeding into the fuse box. And check the wire for resistance per the instructions.
If the photo shows the actual condition, with you using a FH020 R/R, you can cross off R/R failure as a possible cause. Those units are bulletproof.

Thanks for the reply, Tried that build and 0.5 volts drop between + R/R and battery. I'll try to open all my connections and clean all contact.

Some pics of my test.

R/R + go to the Factory plug
R/R - go to the battery -

Using oem stator. 80V between legs
If I disconnect the - stator output from the battery, I have my +13V bike running idle. When connected drop to 12.5v

Someone have picture of a sh775 or like me a fh020 ?

Thanks

Exactly, with a fuse between the battery and the R/R positive jumper wire.
Is that a glass fuse or a blade fuse.
As Nessism pointed out, disconnect that jumper wire at each end and ohm it.
That fuse may be dropping some voltage.

”f I disconnect from the battery the negative R/R output”
I’m not sure how much voltage that R/R would be able to put out if it was not grounded.

Take a look at Nessism’s picture. If your R/R is hooked up like that, and the bike is running, the main harness would be drawing current away from the battery AND from the R/R. The bike may be pulling more amps from the battery and regulator than they can provide when under load?

Question for the experts: Just because a R/R is producing X volts, how many amps is it providing?

Depends purely on load. Up to the maximum the stator can supply, which in these old ones isn't all that great, about 15A iirc.

That's mean I'm good ? I'll try on road.
