Compressor Question - Jumping wires to start undercharged compressor
It has been a while since I have done it but I have started the AC compressor by jumping two of the three wires in the plug on the line located on the line right near the CAUTION FAN. There is a black, red-black, and green.
Trouble is that I can not recall at this time which two you jump.
The switch measures the pressure in the system. If the system pressure is low the compressor will not start and can not be charged with freon. With the jumper wire in place the the compressor runs and it takes freon.
Does anyone recall which of the two wires are jumped to start the compressor so the system will take a shot of freon?
Thanks in advance.

I just looked at the service manual and it looks like shorting red to black will make the compressor run.
Looks like the red to black to get the comp running. Found it in a previous post.
