solenoid problems
Having ongoing problems with solenoid switchs sticking in the on position causing the starter to not dis-engage. Have seen several posts advising to use a stock ford part. I have been using aftermarket switchs with no success, does it really make a difference or is there another problem. Any advice would be appreciated !!!

Just a thought some of those starter solenoids are only good for 50-60 amp's & good battery can put out a lot more than that. So if the starter is getting old or worn it maybe pulling A excess amount of amps and welding the solenoid contacts. Maybe pull the starter and have it tested: Napa/pepboys/AutoZone etc. etc.& if its good they should be able to tell you what amp solenoid you need.

What I posted in similar post.... did you ever find the problem/fix?
My 91 F150 302 auto has an intermittent starter staying engaged once I go to start it, it will stay engaged once the engine starts/runs, also stays engaged once I turn off the key (even pulling it out). So I would jump out of the truck, grab my hammer (only because it is in reach each time), open the hood and tap the fender mounted solenoid which in turn will immediately stop the starter from continuous cranking. I can usually go inside the truck and start it back up without it happening again. This happens every 2 or 3 times I go to start it. I've read some people say it's because of the bolts on the starter are not shimmed correctly, and others say the back of the solenoid on the inner fender is not grounded to the fender. I have yet to go out and try cleaning the back of the solenoid to fender for a better ground, but has anyone else had this issue? Yes, tapped the solenoid with hammer lightly stopped it and can drive on is only a temp fix for now.
