Engines Dead!! Wont start

The solenoid has 2 tasks, one to pull the solenoid armature into the solenoid core thereby engaging the starter pinion with the flywheel.

The second is to close a big, high amp contact between the battery and the starter motor.

I've taken solenoids apart and turned the big contactor disc to a new position for solid power to the starter motor.

Solenoids are not sold separately.

On a 74 I would investigate the seatbelt relay that was a 74 only thing, it won't engage the starter unless the seat belts are fastened most were by passed by unplugging the seat sensors leaving the relay intact this relay does wear out and the car won't crank over. Search seatbelt interlock and you'll find a few threads on bypassing this relay for good.

Thanks guys for the input.  I think what you are saying is that perhaps the problem could recur and the things that you suggest will reduce the likelihood of that happening.  Much appreciated.

Just posted in another thread revival to show what I found in my quest for a seatbelt interlock disable.
