Thanks everyone, it's been helpful. I think something in the computer is bad. Can trip the compressor by using a light tester connected to a ground and then tested it at the connector, and at the soldered pin in the circuit board it self. System pumps up fine but but does seem to leak and won't trip on its own. Could it be a bad ground somewhere or do i need to try and find a new computer? or could it be that the reed is stuck somehow and the computer not getting a proper return signal?
