Starter Run on
I tried to start my 67 mustang (289) and the starter would not disengage and kept turning over after the key was turned to the regular (running) or off position. Smoke started to appear as theRED TOP continued to fuel the starter.It an old starter. Is the started jacked or is it the solenoid? The solenoid is newer... (2 months)

RE: Starter Run on
Could be that God was feeling mischivious too--Any more guesses?"
Now lear how the system works--When the key is in the start position the wire attached to the small terminal on thebattery side of the relay energizes the solonoid. Inside the soloniod a round, flat copper disc is magnatically sucked up to contact a flat area on the inside of both the terminal on the Battery Side and on the starter side. Current then flows to the starter until the switch is released. The other small terminal if so equipped send full battery voltage to the coil while the starter is engaged.
When the starter is engaged it also engages a drive unit which forces a small gear into the engine ring gear hopfully the engine will then start.
Apparently all of these events are happening. So now what is supposed to happen? You release the start switch which SHOULD cut the current to the energizing terminal. The current being off should deenergize the relay. The internal spring SHOULD push the copper disc back down. The starter mothor SHOULD stop turning and the return spring for the starter drive SHOULD pull the drive gear back.
You don't say what happened before the problem started. Could it be that you tightened the nuts on one side or the other of the starter relay? That would be my first guess. Suggestion try it again. with the hood up. Key off. Energize the relaywith a screw driver across the battery terminal and the energizing terminal- Crank for a few seconds then release--If it keeps cranking beat the realywith a rubbermallet or hammer. If that stops the problem replace the relay, carefully. As simple as the appear to be relays are hard to fix.
If that doesn't work use the other info I gave you and use it to diagnose the problem.
