Replaced all the spade connectors and the molex plug on the pigtail from the alternator.
The old connectors were fatally corroded.
Small wonder the battery wouldn't charge.
Then I installed a solid-state voltage regulator. I used a VR124 (for the '76 Porsche...)
I might clean up the mounting later, I just stuck it in there Q&D.
It works great! Thanks to everyone in the "cheap regulator" thread!
Tomorrow.....I ride!
