I have my car wired like most racers with the ford silonoid and I was cranking it the other day after chaging all my fuel filters so therefore engine had to turn over several times before getting fuel restored but during this time I noticed the starter wire end at the ford silonoid tured red and started to smoke I have never noticed this. My battery died soon after. Charged it up and it crunk fine. My question is what caused this. Is the car wired wrong? Starter going bad-would that cause it or what. My timming is locked out @ 36 degree.

Also run a ground wire from the engine to the frame somewhere, this is usually the cause on street stocks.

I have it grounded at engine and battery, also last week someone said it sounded like my starter was staying engauged but how could this be and how do u tell or what harm will that do, He said that has I was shuting it down that it sounded has if the starter was engauged but any how I dont know if that would have any effect on the problem with the wire

the only way your starter would keep going is if your push botton had a short in it that is the only source of power going to the starter as for the glowing wire check and make sure all the bolts are tight on the solenoid and you might want to shim your starter a bit might be to close and that could be the noise they are hearing if the head is getting stuck in the out position also with that continous turning may have got the starter hot and cause it to pull to many amps. next time you change filters pour a littel fuel in the carb to get it started first may take a few times before it will run on it's own but is alot easier on the starter

It's a bad or corroded connection. High resistance gets hot fast and the current draw from the battery increases quickly. When the resistance goes up the current draw goes up and the voltage goes down. It's an easy way to find a problem. Crank your car for a little bit then touch the cables and connections. The hot spots are future problems.

Good luck,

new car with new wirong but I will check all wiring again and connection. I have the engine grounded in two spots and the battery grounded also, the silonoid is mounted to the fire wall should it have a ground strap to it to or should it be ok with just the bolts that hold it up there

make sure you dont have small light guage leads they cant handle the cranking amps they are ok for normal crank. i never reccomend spinning engine over that much if you can help it hard on starter. maybe try running car a couple minutes first so its warm and will idle good carb is full of gas shut down change filtrs

An overheating electrical connection is a loose/dirty connection.And a overheated senolid connection will overheat the solinoid and cause it to stick.This will cause the starter to stay ingaged.If the started is overloaded/dragging ,the cable will get hot at the starter end first.I hope this helps.

rat with a ford solinoid it can stick all day long as long as the push button is not pushed there is no juice there to keep it running the only way for a starter to keep running with the ford setup is to have a push button stick. or if some how your body became live and the starter wire was bare spot and touched it would turn but how likley is that to happen

i had a f100 pickup that the starter would do this if the battery voltage was low.

ok here whats I came up with and it may not be the solution but I think it is for now. After charging the battery back to full power I went to check the connections at the silonoid and found the m to be a little lose. The starter wire was lose enough that I could move it just a little, I had broke a couple by overtighten them so I guess I never tighten it good enough. How ever I hit the switch and guess what It did nothing just a little thump, but when you cross out the silonoid motor turned over really great. I put a new silonoid on it and made sure it was tight and its cranking really well for now and is not getting red anymore. I have a preety big wire so I dont think thats the problem but would have been a good place to look. I am thinking loose connection and I never noticed untill I had to turn motor for so long after changing fule filters to get it to crank. Loose connection got wire hot enough to burn up silonoid, any way thats whats I hope cause Its runnin great now. thanks all

glad to see u found problem, im just posting to say i can gaurantee a ford selenoid will go bad and stick and keep cranking regaurdless of pushbutton untill u remve battery terminal or smack it with something it costed me a new starter over a cheap selenoid sticking a few times my fault for buying less expensive one.
