1975 Cub Generator

Postby Jamesk » Sat Dec 08, 2018 12:32 pm

My generator doesn’t seem to be charging. I’ve had it tested along with the voltage reg and it supposedly is working fine. But not for me.
1). I have power at both post on the ampmeter.
2). When I turn the key switch on ampmeter shows discharge.
3). When trying to polarize the generator (battery to generator at the regulator post) I get no spark.
4). So I tested voltage at the regulator. Both the battery and generator terminals show 12 volts.
SHOULD BOTH TERMINALS SHOW 12 VOLTS???

I have a new Brillman wiring harness and is wired per their instructions.

Thanks in advance.
JK

An added note, I’ve been theough the trouble shooting flow chart and it appears that the generator isn’t charging. Not good

The only time both the Bat and Gen terminals of the regulator should read the same is when the engine is running and charging. But then it should be around 13.5 volts. My thoughts are incorrect wiring, or bad generator/ regulator. Hard to tell more than that without being hands on. If you want to bring it up, it will only take about 5 hours each way as a quick estimate. Better bring/buy some long handle underwear though, we are running high temps around 30 degrees. :cry:
If you are not part of the solution,
you are part of the problem!!!

What’s weird John is the generator was checked out and showed to be working. I’m not sure I’ve got it polarized. I disconnected the wires to gen and put a jumper on the two generator post. Cranked the tractor, I don’t get a constant voltage reading. But I think the generator has to be polarized to generate power.

If I had a covered trailer I’d be on the road headed your way right now. As far as I know this is all that’s needed to complete the little tractor. You gotta love it
