Well Jim, since ya don't have any year, make or model of your truck listed I have to assume that we're talkin’ bout two different animals. This is for a 1950 delux heater, two speed.
The paddle switch only has OFF-HI-LO positions on it. As I said in the original post, "I thought that the wire wound resistor on the back of the AD paddle switch was a voltage-dropping resistor to slow the motor down in the LO speed setting. I just assumed that the motor was a 6v motor and on high speed was wired direct and took the full 6v".
Meaning that the wire wound should only be in the circuit in the LO position.
The point of the post is that it is hot even in the HI position.
It’s a simple matter of pulling the switch out and checking the circuit, I just have to get time to do it, kind of busy this time of year. Just thought someone here might have analyzed it before me.
