Starter help! Starter continues to turn seconds after car fires

[91stang50GT]

Like the title says, when starting the car, the car will fire fine but it seems like the starter gear stays out a few seconds to long and makes horrible noises after the car starts. I previously had a starter off a early 90s thunderbird on my car and now i just put on a starter off of a 90 towncar and both have this problem. I included a picture of how i have the solinoid that is attached to the starter bypassed.. The red line represents the starter wire that runs from that post to the firewall soliniod. The green line represents a smaller wire that runs between the two posts.

any help will be appricated

That looks like the ministarter that uses the same wiring
scheme as the 91 and later Mustangs. See the attached
diagram for proper wiring.

Have you tried replacing the solenoid?
That is what it sounds like to me.

I just had this issue and mine ended up being the gear on the starter was getting stuck in the flywheel. The way the starter works is the solenoid engages and kickes the starter gear out into the flywheel. When this happens there are contacts in there that connect and it energizes the starter motor. So if the starter gear stays out then the starter motor stays energized even if the solenoid is no longer energized. Then as soon as that starter gear gets unstuck from the flywheel it returns to its normal position and the starter disengages. I would put a small dab of grease on the flywheel and starter gear and put it back in and see what happens. Also check your voltages at your relay and solenoid and make sure your getting your 12 VDC signal when your suppose to be.

It's kinda sounding to me like a feedback issue when the starter is de-energized. Provide more info about how the fender solenoid is wired.

Good luck.
