just installed a new mini starter. starts the car great, but it seems to keep spinning for about 3 seconds after the car cranks. any one know why?

got it from mustangs unlimited. procomp - pc2107

 

I don't know much about mini starters, but obviously it is defective. Send it back to Mustangs Unlimited and either ask for a refund or have them send you another starter. I understand that Mustangs Unlimited is not the best of companies to deal with. You might want to mention that you are a member here, and that if they don't want their name tainted further to take good care of you.

 

thanks, i will.

 

Here's a thread on another board regarding a similar run on problem with PMGR starters.

Buckle your seat belt,,I've had nothing but trouble on shipping issues with them, including a couple times I HAD TO PAY TO CORRECT THIER SCREW UP,,, seems their fast on getting product out the door ,,but slow on the exchange /reship thing and guess who ultimately eats it

 

Read the link James W gave above...
How do you have it wired? If you wired it incorrectly, it will "run on" for a couple seconds.
