70 up charging system upgrade question

I'm leaning towards switch. If I'm correct whether its "start" voltage or "run" voltage, they both go thru switch. Switch and the ballast(that I can think of) are the only 2 common pieces associated with both run and start?
Thanks

Constant volts in start circuit with key off,yet won't start on start. Sounds backwards don't it. Sounds like crossed wires... Gotta think on this...
