Can anyone tell me why the compressor works when I connect it to an outside battery but I can't get it to run any other way? (using jumper wires)
It's not the thermal switch or the pressure switch. Anyone?

Are you using the eas connector to jumper it or relay 20?

I tried both ways and can't get either to work.
