Answer
Carl, you need to check all of your wiring and your grounds. IF you painted the frame and other parts, you may have lost the ground path to some components. You may also have grounded a hot wire inadvertently. By 1976, most Ground wires were GREEN and switched HOT wires were black.
Go over the harness connections and inspect each one carefully. Check where the ground wires go and be sure that that area of the frame is scraped off so the ground wires are connected to clean METAL.

I would NOT recommend trying to start the bike from a charger or a car battery. I would unplug all the lights first and see if your problem ceases, then plug in one at a time until you discover the problem.

A wiring diagram from an owner's manual or shop manual will be of great assistance to you.
