Code # 41

Code #41 overtemp error. I am getting this on a truck that is not hot. Maybe one hour off of a charge and this code appears.
Where is the temp sensor on this unit?

To expand on the last response:

The graphite/copper dust from the commutators gets inside the plugs and conducts enough current to make the system think that the motor is over temp.
The same problem exists for the brush-wear wiring

If the motor checks out fine, ( and this is not the proper fix ) remove the temp wires and tape them off

temp sensors are inside the motors. check that the airways are clear.front band on the drive motors get blocked with crap nd roast the motor very quickly
