disconnect the 2 wire at the furnace and at the condenser leave them hanging in the air. Take an OHM reading between the 2 wires . you should get no resisatance of any kind . then check each wire to a good ground. again you should get nothing . Tie one end of the wires together. take a reading . it should be very low resistance (less than 10) .
If those check out then the problem is in the condenser most likely.
Check for resistance to ground on the wires going into the condenser control circuit . there should be none.
