I have a problem with my '89 F250, I went to crank it and the starter stayed energized after the engine had started and I released the ignition switch to the run position. Realizing the starter was still engaged I switched the ignition off and removed the key, the engine stopped running but the starter stayed energized and engaged so the engine kept turning over until I removed the battery cables.
I originally thought it was a starter issue but the more I think about it it has to be electrical to have stayed energized. Has anyone seen this before or have an idea where i should start looking?
Cool, I've got a basicly new one on a junked '87 F150 that I can rob. Funny thing is we had the opposite problem with it, starter wouldn't work at all.
there are a few things that will cause this problem, with the primary one being a bad solenoid.
but a weak battery can cause the solenoid to stick too.
Ok so it could be either as the battery in the truck was low at the time. Lately the truck is pretty much "yard art" until I get the coin to continue this project. I was just moving it to cut the grass where it is sitting.
Just to make sure we're talking the same part, the solenoid is mounted to the fender just behind the battery correct?
Okay so I have a new question. What is the electrical connector for that comes out of the wiring harness on the back side of the rad support and is crimped in with the negative battery cable? Are they available aftermarket or am I looking for a junked truck with a good connector?
are you talking about the wire that comes out of the battery cable connection and goes to the radiator support? that is just a body ground.
you can make a small wire that goes to the bolt on the cable end and screws to the rad support.
No, this is actually 2 small wires that come out of the wiring harness and go to the negative cable with a plug together connector in it. The reason I'm asking is tha connector is brittle and broken so I was looking to replace it. Some PO did a hack job repair on the wiring aound the battery at some point and I'm trying to straighten it out and make it look better.
ok. it i still only a minor ground connection. if the connection is crusty, i would just cut it off and replace it with crimp connectors and some heat shrink tubing.
Thanks for all the help Tom. Hopefully i will have time to finish it up tomorrow evening. I think I will start a build thread on it soon as I get rolling on it good as there are a list of small fixes this truck needs and I'm not overly familiar with Fords. I am sure I will have other questions along the way.
Had the same problem on my 89 F150, solenoid stayed engaged and actually fried the starter. I replaced the solenoid and the starter...so you're lucky! Good thing is the solenoid replacement is an easy 10 minute job
And based upon recent experience, stay away from Echlin. They used to make good stuff, but apparently not anymore. I replaced the failed solenoid on my truck. The first solenoid lasted about 8-10 start attempts before sticking in the engaged position. The replacement lasted 2 attempts before sticking engaged. The new replacement (sorry, don't remember the brand, but made in Mexico instead of China) has lasted so far.
The battery was fully charged, and despite the claims of the Echlin distributor, the battery cabling is just fine. You could hear parts rattling around inside after it failed. My guess us that the springs are failing.
