Default Starter solenoids keep sticking and then going out. What is the cause of this?

My car keeps breaking down. It'll work fine for a bit, then one day I'll start it, the solenoid sticks and my car is running and still trying to start itself. The only way to stop it is to pull the negative battery cable.

I reconnect and my solenoid is zapped. I replace the damn thing and two days later the same exact thing happens. What is the cause of this? I have tried the 9.99 cheapie solenoids from autzone and well as what they call they "heavy-duty" 19.99 solenoids.

Who else has suffered from this?!

One thing to note...I have a 130 Watt Alternator with a 6 gauge wire that runs from the solenoid to the Alt. Just an FYI in case you think it could be a contributor to my problem.

mostlikely, your problem lies with the starter....if the starter is on its way out, it will pull too much amperage "welding" the contacts in side together...thus not releasing. have the starter checked.

Or if your car had the old style large starter, and you replaced it with one of the newer mini starters, you'll need to run a new circuit.

Maybe try a Ford Solenoid too.

Your solenoid has a bad connection, check all of your cables and connections, and make sure it is mounted firmly to the fender. If the mounting holes are stripped out this problem will continue due to the bad ground connection. (chased this problem nearly 3 months, went through nearly a dozen solenoids!) The solution for me was to drill new mounting holes for the solenoid right next to the originals, and install new sheetmetal screws, had problem-free starting for a year!

Also, charge the battery before starting it again, the solenoids on our 5.0s are pretty sensitive, especially for the first few startups, they want a fully-charged battery, even 50 CCA less than factory will often keep it from working properly on the first start and lead to another failure later on.
