Hello. I think that you have just exposed the problem. A decent solenoid costs twice that much. Get the Borg/Warner and, more than likely, your problem will disappear. What it looks like you have happening is this. Dead cold the motor cranks much easier than it does hot. Cranking while hot requires more power, along with the increased demand placed on the battery by the electric fan. Low current makes the solenoid heat up a little more than it would when the motor is cold and the fan isn't running, and that is causing your cheapo starter solenoid to stick. If you go to my home page and type 'starting system' into the search thingy, a detailed description of the starting system, along with diagram, will be about half-way down the page.

Sorry I didn't jump in on this any quicker. I've been running around a lot doing all sorts of 'end of the school year' stuff with, and for, the kids.

I either pulled the batt. cable or messed with the ign. switch to get it to stop.

As Veronica stated, you do have the additional power pull from the electric fan and you said that the fan acts strange when the starter locks in and spins forever. probably would be good to figure out what is running off of what pole on the solenoid so if you need a higher rated .

Thank You for the reply Veronica. I would totally agree with you that it is a cheapo solenoid, but then why would it all of a sudden start occurring one day in the winter after it was sitting for 3 months. As i believe the first solenoid we ever had was from Napa as well as all the other replacements have been too. Yet prior to this winter my Mustang operated for 5 years with no problems on this first solenoid. I have bought the cheaper and more expensive one at Napa and both are the same problem. I also called Mustangs Plus and they said that their solenoids are bought from a local auto shop or Scott Drake and they are the same thing as getting one from Napa. Where would you suggest i get a higher rated solenoid?

I have been researching solenoid's a little online and one thing to note is that i put a rebuilt 83 Lincoln V8 5.0L in my 65 Mustang. I believe when i have been purchasing the solenoids at Napa i have been telling them its for a 65 Mustang V8. When i look at checkers auto website they have some solenoids for a 65 Mustang but also one for a 83 Lincoln V8 5.0L (the engine i have), so what one should i be purchasing? The links are below, the first two links are for the 65 Mustang solenoids (do you think there is any difference between the two) and the third link is for the 83 Lincoln solenoid:

Thanks again for all your help.

I would say to get the one for the 5.0L engine.

Okay so tonight (after having the new ignition switch has been installed) i repeated the test that we have been conducting in which it has failed the last 3 out of 3 times. However tonight with the new ignition switch installed we could not get the starter to fail by staying engaged. We did the exact same test which was to start the car, drive it for 10 minutes, come back to the garage, turn it off, start it back on and then turn it off and let it sit for 10 minutes. It is after letting it sit for these 10 minutes (after having driven it) that it failed the last 3 out of 3 times, but tonight we could not get the test to fail. I am crossing my fingers that this new ignition switch has fixed the problem. Also tonight we kept letting it sit for every other 10 minutes and even with the engine fan kicking in or when i have poor fuel pressure and have to hold the starter awhile we could not get the starter to stay stuck engaged tonight. It seems really weird that it only did it at this specific time (after having driven it and then letting it sit) and how the ignition switch MAY (crossing my fingers) have fixed the problem. More driving will be done tomorrow to continue the testing and rebuild confidence in the good old Stang. Either way i will report the good or bad news tomorrow as i know this is a pain and i want other users to be able to use this info if it ever occurs to them.

Thanks again for all your help and hopefully it continues to work.

Alright i repeated the driving and sitting test again today and no failures yet. It seems to be working ever since the new ignition switch was installed. If it fails again i will be sure to write otherwise my confidence is slowly starting to build in the Stang again after a 2 for 2 success rate on our tests that we have conducted.

Thanks again for everyone's help, about 250 bucks later i think the problem may have been solved. If this problem occurs to others make sure you read up on the issue a lot and not rule anything out. While mine appears to have been the ignition switch i have read that many other users on the web (not particularly on 65 mustang's) have had a bad starter, a bad solenoid, poor wiring, or even a bad battery. If your symptoms are exactly like mine you may start with an ignition switch to try to lower the $250 expenditure that i sunk in trying to diagnose my problem.

Good luck, and hopefully this post concludes my problems on this thread.

Hi again. Cool. Glad you got it figured out. At least now you know that you have all brand new stuff in the starting system of your car.

[pologoped2]

So after about 4 days of successful driving the starter got stuck engaged again yesterday, however this time the symptoms were different. Unlike previously, this time the engine started and was running while the starter remained engaged. Also, when i turned the key to off and took it out nothing happened, the starter and engine both kept spinning. Also, after i pulled the battery cable it killed everything but when i put it back on the starter remained disengaged, which indicated that the solenoid wasn't arc'ed together like it had been always prior to replacing the ignition switch. I don't know what happened but i can't seem to get it to fail anymore right now, so i will continue to monitor it.

After the ignition switch was replaced the problem seemed to have decreased its occurrence significantly. However it would still occur here and there. Today i replaced the voltage regulator as i was only getting about 12.8V from the battery while the car was running and i know it should be in the 14V range while running. Now with the new voltage regulator in, i am receiving 14.4V while the car is running, hopefully this corrects the problem once and for all.
