Re: Electric fan conversion

Spal doesnt make their fan controllers anymore. Theirs can run the fairly cheap, low amp drawing fan motors but they never could handle high output factory fans-they had at least 3 "latest versions" of their PWM controllers with the last one having features like under and over current protection where they would just shut off if the fan motor pulled more than 25A and crap like that. Tried and true relays with temp switches is the way to go.
