With all the electrical issues you are having with this puppy keeps making me say - grounds. There has to be a bad or missing one somewhere. Get that wiring diagram downloaded and recheck them all. Check connectors for pulled out wires or corroded ends also.

Electrical gremlins will almost always lead you to ground. Even those that "look fine". Take them all apart and douple check to make sure they are making good contact.

On the 2 and 3 we had a lot of problems with the connectors, most all were aluminum. In Jersey it was salt, Tucson extreme dry then extreme wet during monsoon. And add 115 and aluminum electrical wiring or connectors. Normal part of annual was to take all main electrical harness apart to check connections. Anyone remember the aluminum main starter battery wire?
