My 1948 Ford 8N's ammeter has shown a constant slight discharge for several months. Yesterday the battery finally died completely and I replaced it (old one was bad -- 12 years old with plates visibly corroded).
With the new battery, the engine started right up fine, but the ammeter still shows a slight discharge, even when I rev up the engine.
What is the next series of logical things to check? The voltage regulator looks ancient -- maybe orginal equipment. Can I just buy a replacement and install, or do these things need to be "set" somehow?
Maybe I also should take apart the generator and check brushes etc.?
I saw the recent post on a 4400 with discharge problems and some advice on re-polarizing the generator. Not sure how I do that (8N has a positive ground).
Any advice appreciated.
