I have run power directly to the compressor and found it works. I have swaped out parts I took off another PA that was scraped with a blown engine. I know that system worked and I took all the parts and wires except struts. Still nothing. I had to put in a new battery last week. It pressured up and exausted once and has not worked since. Have not had time to try disconnecting the battery again.
