Why was the heater fan reversible?
The old forum topics seem to indicate the motor was reversible. Why was it designed that way? I guess I am just intrigued, I have not heard of a reversible heat/defrost fan motor before.....
I am running the old KB-7 cab and all the original devices on a 12 volt Chevy C-40 chassis. So I assume I will have to install resistors in my wiper and heater fan circuit so I don't burn up the 6 volt motors. I did install a resistor unit for my gauge cluster. The heater core and blower motor seem to work good. I have not tested the wiper motors yet.
