f53 starter solenoid
i just replaced my starter solenoid for the third time in 6 1/2 years, anyone else had this problem. it just sticks and i have to bang on it to get it to work.

Insufficient current to the COIL of the solenoid turns it into an CONSTANT DUTY SOLENOID (sort of). Like comparing an 80 amp constant duty solenoid to a 400 amp intermittent duty solenoid. The difference is in the strength of the magnetic coil. Strength is amperage. For high amperage duty, those contacts have to slam together TIGHTLY. If the least bit of tension is missing, the contacts will start micro-arcing, which does not degrade the contacts in a linear age or usage factor. They go to hell in rapid fashion.
Since LBJ was in the White House, I have been utilizing FORD FENDER MOUNTED STARTER MOTOR SOLENOIDS transmitting starter solenoid power through TEN AWG wire. Diesels like 855 Cummins get 8 AWG wire. I want every last freakin' watt available to pass through that starter motor solenoid. No chatter. Replacing a flywheel or flex plate ring gear is bad enough. Doing it to a one ton Cummins engine with 1,500 lbs of Fuller Transmission hanging off the back is a real fast learning experience.
