TractorDude 7 #1 Posted October 27, 2019 I finally finished restoring my C-105 with a K241as engine, but noticed that if I turn on the headlights with engine running, the ammeter goes negative.

Should show charge briefly after starting up but after running for a bit it should go back to Zero. If the battery is bad it will continue to show a charge.
