How to hook up the A/C in its simplest form?
Question for all of you ac gurus. My 72 250/8 at one time had ac. It was missing the tension pully and I was able to find one at the local boneyard. I put a new belt and started the engine. I'm sure there is no freon left and the compressor probably needs oil. I was not able to get the compressor clutch to engage, so I ran a wire from the 12v + of the battery and touched the terminals on the compressor to engage the clutch. It worked and the compressor sounded fine did not blow up. So now I am wondering, what would it take to just wire it up so that the compressor turns on and gives full ac with no temp control? Thoughts and opinions?
