hmmm, bad brushes on an electric motor will cause it to slow down and draw more amps. I have two M103's and they run at the same temp based on measuring with a $95 IR thermometer, but they read about 10-15 different at the dash guage. I don't have much of a solution, but the IR thermo is fantastic at diagnosing cooling system problems. You can point it at the inlet and outlet at the radiator and determine how much cooling is happening, you can also determine if the thermostat is opening, if a cylinder is running hot, the temperature of the fan clutch, the temperature at the temp sensors, etc, etc.
