Re: Radiator Fan
If you know what clip leads-test leads are you could hot wire the motor for a FEW seconds to see that the fan is good before you get too far down the line. Basically you unplug the fan connector and apply 12 volts to the fan. Polarity is not an issue so + and - wont matter FROM THE FANS PERSPECTIVE.
If you wanna pm me with a phone number a specific EST time, I could assist you on the phone if you like, again assuming you wanna do the clip lead tests.
Fans are basically a DC motor fed from the fan module on the driver fender which is a pwm controlled power source ranging from about 4 volts outputs to about 12 volts at MAXIMUM fan speed ( Scary fast at 12 v).
