I have been wracking my brain, looking over wiring diagrams, testing different connections, and generally losing it since Monday. Today, I solved it. One of my positive battery cables was contacting the fender where the wire is bare near the terminal. That’s all. It has all of the electricity now. Tons of it. No electrical woes to speak of.
Now I just need to get thread sealant for the regulator fittings, and I can tune it better and finally drive it with the new Weber.
But tonight, Thai food, and beer.
