Not sure my ammeter is working, Luke.I have a '53 Cub and '53 Super H (both 6 volt, pos ground, with generators) , and have been through similar issues. 6.31 volts is a good reading for a battery at rest. You should see around 6.7 volts at the battery with the engine running and a good charging system. The ammeter (the only gage on the Cub dashboard) should move left of center when you turn on the ignition (prior to engine start). After engine start the ammeter should move to the right side of center, settling to just right of center once the engine has been running for a few minutes.
I had a bear of a time getting my charging systems to work properly. Turns out the cheap voltage regulators I bought at Tractor Supply, CaseIH dealer, auto part store were junk. I ended up going to Brillman.com for USA-made units at 2-3 times the price. But they work.
Thanks for the good info.
I'm going to see if I can learn how to test this stuff.
Not terribly clever in figuring this stuff out
