Does anyone have any electrical information on the heater circuit? My heater does not work. I replaced the defective components on the heater amplifier circuit board without sucess. the motor flys with 12 VDC applied, but I am not sure if I have a bad heater amplifier cuircuit board or a motor, or both?
