You may have given me some thought on why I cant find a heater switch for my '55 3100. I have tried several with no luck. The last from a Volvo rheostat type but started smoking. Now I think I may have a 6v heater motor in the truck. Is there any way of finding out? Perhaps some way of knocking down the voltage to the motor?
After all the work on re-coring the heater itself I cant control the motor.
