Been working on the air in the windrower. The compressor will only run for a second or two than shut off for 3 or 4 minutes. If I bypass the low pressure switch it will run steady and the lines at the expansion valve get cool. So I assume it is low on freon and add a can. No difference. Add another can with the same results. It is a R12 system converted to R134. I just used the cheap cans from bomgaars with the gauge and when the compressor would run the pressure would fall to zero. If it is leaking it all would it not loose all the vacuum in the system? What am I missing? Its been a long day so I have to be overlooking something.
