Testing motor and esc?

[nastety92]

I have a Stampede with a MM esc and MM 5700 motor in it. I was using the truck last week and it just stopped running. Everything was pretty hot, motor, batteries and esc. I was running a 6-cell 4200 battery pack at the time. When I plug the esc into the computer the lights on the esc will light up. How can I start testing the motor and esc? Does the MM esc have a shut off if it gets to hot?
Any and all help would be greatly appreciated.

Thanks,
Nick
