First off I don't know if it is 6 or 12 volt. I am going to assume( I know, I know) it's 6 volt cuzz it's in my 52. It has one wire coming off the motor. Touching it to a 12v battery does nothing. And if it does work, are the resistors sold by LMC made for this application, going from 6 to 12 volt, worth it or should I just spring for a new 12v heater motor?
