Not really sure where to start, need help..

Definitely go to the electrical forum. When you get to running the compression test. PLEASE pull off the rubber fuel line from the fuel pump if you have not cleaned the tank to avoid pulling garbage up into the carb and engine.

Let us know how the rust evaluation of the body goes. One thing in favor of the /6 if this moves forward: it is a fairly easy and less expensive training ground for engines IMO.
