Re: Compressor problem

If the light goes out when you plug in the PWM and the compressor is still running you have a wiring issue. The LED off indicates that both outputs are switched to +12 and that would not run the compressor. I suspect the wiring was changed or one of the wires is pinched and is seeking return through the chassis and some other fault.
