on that insulated suction line coming out of the condenser...press the shradder pin down and get some oil and freon on your finger. if it smells burnt the compressor is shot. is the contactor ark'd at all.remove the terminals off the compressor and ohm the termnal to the copper pipe....any read or audible the compressor is grouned....should have a dead short/and or resistance reading between terminals as which is normal
