Wiring a modern electric cooling fan, PWM controlled - 07/13/21 11:04 PM
Hello all. I've got a question for you. I see a lot of new car/truck fans, and they no longer use just a normal 12v hot/ negative ground. They all seem to have an extra white wire, sometimes green. I know this is for PMW control. Is there an easy way to use these new style fans in a retrofit application, and how do you wire it?
I have seen the Derale controller called "pwm", but it doesn't control a pwm fan according to the instructions. It just makes a variable speed fan, with only a two wire hookup.
