gmanmadera Posted February 23 Report Posted February 23 Need to know how to wire heater switch on 1948 dodge truck Quote
Los_Control Posted February 23 Report Posted February 23 Interesting question. Since the heaters were offered as a option and not shipped with the truck. They were either installed at the dealer or bought aftermarket and installed from the owner. When I went through my heater I wanted to test it to see the motor actually did work. I had no idea which wire was ground or positive. I just connected them to a 12 volt battery .... It truly did not care which wire was hot and which was ground .... it ran really fast since it was a 6 volt motor on a 12 volt battery. I'm only suggesting that this type of motor does not care, it will run and spin in the correct direction no matter which way you wire it up. I have been wrong before , I have no idea which motor you have by reading your post .... just touch the wires to a battery and watch it spin. I get it, sounds like a really stupid answer to a honest question .... Honestly the way some electric motors are made or wound .... they really do not care. The electric heater motors are one of them ..... in my experience. Quote
JBNeal Posted February 25 Report Posted February 25 Agreed, the heater wiring is very simple: voltage source (usually key:ON) to fan speed control switch to fan motor ? Quote
