Thermostat Condenser wires energized when they are apart of each other
When they are join together, one does not get any reading.
Disconnected the two wires that come from the condensor - one was connected to the relay inside of the box and the other one straight to the thermostat.
It is strange, but while having the two wires disconnected at the junction after the relay box - I was getting 24v across them coming from the thermostat, when joined together, I was not reading anything at the exact junction.
Disconnected the relay and as far as I understood the schematic, I think it is fine - correct me if I am wrong:
1-3 coil ----> about 78 ohms of ressistance
5-6 -----> it read NC
2-4 -----> it read NO

Welcome to the forums.
I see the relay and wiring. Not really sure what the problem is or what the relay is for.
What is the problem you are having ?
DON'T short wires together. The two wires coming from the thermostat inside the house should have 24vAC on them if the stat is calling for cool. Shorting those wires will damage the stat or transformer.
