You will have to determine what wires are what by reading the wiring diagram.
You will test for 24 volts ac between the 24v common wire and other wires.
In cooling mode you will see 24 volts between :
C - R
C - Y
C - O
In heating mode YOu will see 24 volts between :
C - R
C - Y
If you get those voltages to the condenser circuit board and nothing happens..... then you may have a bad circuit board(if unit does not have a circuit board then post a photo of the unit and control section so I know what parts you do have)
IF the condenser runs in cool and not in heat , then the problem HAS to be in the condenser. look for loose connections or maybe somthing that looks burnt or damaged.
