i have a 1957 johnson 35 hp with generator charging system that is not working. I had generator tested and seems to be fine. Adjusted polarity, but still not charging battery. Battery shows 12.9v without engine running, and about the same when running, even at high speed.. I’m thinking it will be closer to 14v when under full throttle if it was charging. I’m suspect of the voltage regulator....is there a way to test it? Hard to find a replacement, but I think I’ve found one, but don’t want to buy one if not necessary.
