Does fan come on in outdoor just no compressor or neither?
First of all,with power off, remove the cover on compressor where wires connect and make sure all 3 compressor wires are intact (Not burned )
Do you have a volt meter for checking continuity?
I understand. If wires look good, we want to disconnect them from compressor terminals and check for continuity between all terminals on compressor.
You only have one hot wire on cap. That is the same wire that is going to fan and compressor . You will not get a reading on cap terminals.Only from the one coming to cap and other lead on opposie contactor pole.
