my starter circuit has constant power to it have to unplug it at the starter to keep it from running on any suggestions?

 

Shorted starter relay.

 

it is very possibly the starter relay as suggested above.
Could also be switch or less likely the solenoid binding.

I would suggest that since you had to ask, the smart thing would be to take it to a shop that is smart about electricity...but first;

Replacing the starter relay is easy, you could take yours to CDN tire or any auto parts store and they could get you a match for under $20

You should post your city, in case one of the other forum members has a shop to recommend or warn against.
