Tom, Marty I am not sure that there is a low pressure safety switch to jump. I have never seen one on an AMC A/C unit. I only have data on AMC A/C up through 1980. I would imagine 1983 is the same although I do not know when the rotary A/C compressor was first used although I have one in my parts stash along with the hardware to mount it on my Spirit if I ever need it. I think I can locate an A/C wiring diagram as a J-Peg if needed that can be e-mailed to someone if they think they need it. (no promises but I will look if asked) John On Mon, 14 Aug 2006, Marty Bricker wrote: > compressor cycling on.

Assuming there is nothing else wrong, you might need to jumper the low-pressure safety switch to get the compressor to pump the freon into the system. Once you get it close to right you can remove the jumper. I assume you have the right oil charge and all that. _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
