Charging issues help and troubleshoiting

I think I covered the SPG in my Sorted post. Easy. If anything it simplifies things a bit.

stator testing is done with 3 stator wires disconnected from RR. With bike running at 5000 RPM. Check VAC an each 3 pairs of stator wires and check each leg to ground. If this show voltage, it’s bad. If this show continuity, it’s bad.

So you can test the stator that is on the bike now. You’ll want to clip the wires a bit to make sure you have clean copper.

Probably won’t need to run the bike for long but running a fan at the front of the engine is a good idea.

IMG_2688 Large.jpgAll,
here’s the stator- visually looks bad to me. Opinions?
Here’s the question:
should I pull the stator from my donor 82 to install with the new sh775 r/r or will that just continue my electrical uncertainty? No ussue buying a new one if necessary.
I’m waiting on parts to start repairing the broken and burnt wiring, I will do the voltage and ground tests after the bike wires stop smoking upon starting
the most burnt wires are in fact the blue/ white from the stator, both by fuse panel and under left front gas tank.
cheers,
John

Wires can't smoke if they're not connected to power. Again, the stator test are done with the 3 stator wires disconnected from the RR (and the headlamp loop that you will be eliminating).

Rewire the system, use the old stator, along with the SH775, and see what happens. If you don't get 14-14.5 VDC, then the stator is weak. Install the donor unit if it is and try again. If still no love, buy a new unit.

That stator is BBQ’ed…..might produce, but will fail completely.
here’s one of my stators from 2012 on its way out, struggled to produce 13 volts down a steep hill
