1973 valiant 318 car stalls when compressor comes on

These are the ohms I am getting from the compressor ran one wire to the coil and ran the other wire to the positive battery View attachment 1715615119
Sorry I have no idea what you mean, there. If you are going to check resistance of the compressor clutch, connect the meter to the two disconnected clutch wires right at the compressor. "Positive battery" is not in the mix

NEVER hook any external power in with a resistance check.
