So if I jumper it, and it DOES NOT turn on, then the possible culprits are fuses/relays and resistor? I just "rebuilt" the resistor, so I am fairly confident that its fine. I just had the AC recharged too, so I donít think thatís the problem either. Which relay controls the low circuit circuit? (part #, exact location, or even color will help). I know the dark green with built-in 30A fuse controls the high side.
