Ok, I have this 55 series1 1/2 ton truck we are going to try and get started today after not been running for many years. The elect system is messed up so we just want to by pass all other wiring and use battery, starter& coil and distributor. whats the best way to do this without destroying the starter, it has a foot starter No linkage return spring. Ignition switch froze with key jammed in it. Looks like somebody installed a button starter on dash to bypass the foot starter. I do not trust any of the wiring inside the cab. It has also been converted to 12 volt because it has an alternator. If you can just give me a simple one line to electrically start the engine that would be great.
