Electrical gremlin, please help!!!!!
I have a 1979 F100 302, I just put a new starter on it cuz when it gets hot it turned slow, ok, new starter is on, and I wasnt gettin anything when I tried to start it and I replaced the solenoid (its an oe lawn tractor one, with 2 top post, and 2 side post) now its still wont even click or make any noise, but when I turn the key to start position the brake light in the dash comes on, and I'm about to just rig up a push button start, but what I am askin is, what safety interlocks and whatever will make the truck not start, I know about the nuetral safety switch, but that was disconnected long ago, and what do the 2 small wires runnin to the solenoid do, I know one is for start, but is the other a ground or does it do something????????????

The S terminal - converts a small 12V electrical current through a solenoid to a terminal that allows a Large 12v higher amperage current to the starter when the key is turned to start.
The I terminal allows 12 volts of electrical current to run to the coil when the ignition key is turned to the start position,
Get the proper starter relay for that truck and get the battery checked.

Jump the battery + to the S terminal and the solenoid (relay) should activate. If it does not get another (proper) solenoid. If it does then the problem is elsewhere in the wiring. Always use the proper electrical parts for replacements unless you REALLY know what you are doing with electrical systems which does not seem to be the case here.

Yes, key to Start... Light comes on ..then goes out
If you just turn the key to Run (without going to start),the light stays on that is a problem.
My Quote:
The Brake warning light comes on automatically with the key in run, then goes out after the dedicated time.
This should have said: with key from the start then to run...the light goes out ..........

Oh well, while you are picking up the igntion switch grab the correct solenoid, make sure the battery is fully charged.
Good luck, Mike
