deff are you the one i talked to yesterday about it just being you had the turn on set to high?
If there is still a problem, first check to see if the relay is wired corectly by touching the 2 black wires at the
pressure switch. The system should then kick on. If not its the relay is wired incorectly, if so then its possable you have the wrong pins connected on the switch etc. If you would calll me we can go thru your setup and get you running.
