Hello All! I haven't had chance to do much to my truck yet, because I don't really have a garage at our new (100-year-old) place yet, and there's 30" of snow here. And it's cold. haha.
But; I did get a new battery in it so I could fire her up and start to get a baseline.
For background; this is a '34 Chevy pickup. A previous owner converted it to 12v. It had a dead battery and, even with a jump was barely-running when it arrived to me a few weeks ago.
So now with the new battery in it, I fired it up and was trying to dial-in the ignition timing when I noticed the battery was spraying out both weep holes. I threw a multimeter on it and it's pegging >17v. !!!!!
There's an old voltage regulator on the firewall. No markings, but 3 terminals on the bottom of it. Can somebody teach me how that regulator works, so I can understand how to test it? I mean, it's got to have a reference-voltage applied, right?
I recommend that you return your truck to its original 6 Volt configuration. Your life will be much simpler and there will be real wiring diagrams to follow. It's not hard or expensive to find an original style generator.
