starter motor not working
 

Since I bought my car I had a bit of an issue with the starter. If it got hot, either from sitting in traffic or having a little fun, the starter motor itself wouldn't turn for 20min to an hour. Basically once it cooled off it would be fine. Until a couple weekends ago that is. As usual you could hear the solenoid engaging but the motor wasn't doing anything. This time it never went back to normal. So I got a new starter and installed it and it's still doing the same thing. I decided to see if the old starter would turn if I jumped it to a battery out of the car and the motor turns. I jumped the new starter and same thing. However when I do that to either starter there's no solenoid engagement. I turned the crank with a ratchet so I at least know for a fact the engine isn't seized. Could there be something I'm not seeing or did I manage to buy a bad starter motor? I should also mention the old starter smells like the internals are burnt. In fact the night it stopped working you could smell the starter from about 10ft behind the car. Any help is appreciated.

Have to have power to the starter solenoid terminal to activate it; only putting power on the motor terminal only gets motor spin as you got
