the solenoid on the old starter went and I put a rebuilt starter on on 1996 Buick Regal

and now the starter stays rotating weather the engine is running or not I have to disconnect the negative to get the armature to stop spinning.
The solenoid function like it should so I figure that some how there is still power going to the starter even when the ingnition switch is off and the steering wheel is in the lock position. any idea of how to correct this situation

It seems like it is wired wrong...the solenoid is "ON" all the time.
