Testing/adjusting voltage cut-out?

Postby Dave Downs » Tue Aug 23, 2022 5:01 pm

1949 Cub, magneto ignition, generator with lights. Has a cut-out, not a voltage regulator. Generator checks out OK (will run as a motor).

It was hooked up as negative ground when I got it, did not show a charge when running. Haven’t checked the ammeter yet.

Could polarity being reversed have ‘fried’ the cut-out? Could I just re-polarize the generator (with positive ground) and cut-out and have a chance that it will charge again?
