Default Issues unfortunately :(

well, i dont have much time to look at it until next weekend as i am over my head with stuff to do atm, but this is what happened. its a 77 BBC 486 nova, battery in the trunk, 0 guage wire, to the jegs mini starter. the battery was dead, so i had the bright idea of jump starting the car to get it going, first tap the battery was weak and partially turned over, tried it again about 5-10 minutes later and the car tried starting very quickly and effortlessly, but it continued to turn over even after i removed the key from the ignition and got out of the car when i noticed the jumper cables were melting. after pulling the jumpers off the car continued to turn over until i got the terminal off the battery. there was no smoke, no rubber smell, no nothing except from the jumper cables. but now when i try to hook up the battery the car tries to turn over even with out the key in it. what could cause this?

a stuck starter solenoid or starter slave solenoid, or possibly a faulty ignition switch.
most likely have just a solenoid on the starter, try tapping that with a hammer. If there's a remote or slave solenoid, depending how the car is wired, give that a tap with the hammer. But don't tap across the studs with the wires on it, hit the body of it, to unstick it.



remote starter solenoid looks something like this if you have one, would be on the fenderwell near the battery, follow the large cable from battery + post to it.

It's not a problem. Under normal operation the flyweel/flexplate kicks the starter gear back when the engine starts. If it doesn't start and it's set up a little tight on the block the gear will stay there.
Now take an old starter apart and look at how it works, the solenoid pushes the gear out and connects battery power to the starter motor.
If you put power to a starter on the bench, and pull the gear out with a screwdriver (instead of letting the solenoid push it out) it will power itself as soon as the disc in the solenoid makes the connection between the two terminals.

Instead of beating **** with a hammer, I suggest hand turning the engine 1/4 to 1/2 turn clockwise to unmesh the gears.

definitely the solenoid on the starter. replace it and you'll be fine. the solenoid is the part that the wires hook to, when they go bad they are just bad so replace it and be done with it.

Replacing parts is a waste of time and money. Get a strong battery in it and make it start. Once the engine starts I guarantee the starter will kick the gear off, the gear is on the same lever as the solenoid disc. When the gear kicks off it moves the lever, the lever lifts the disc off the electrical contacts and kills the starter motor.


Do you want to hear do this do that, it'll fix it? Beat the **** out of it. Or would you rather hear why it's doing what it's doing?
Any monkey with a toolbox can replace **** until it starts working. If you know how stuff works, you can solve problems the smart way.
Figure out who you want to be and do what you want.
