im gonna be honest with ya without looking at it i cant help but i would look for something grounding out which would cause the circuit breaker to trip. and on the switchbox check the switch for the compressor i think there is gonna be three wires connected to it a power, one to the compressor, and one to the switch box just hook the wire for the box to the battery with a fuse that way it will work at any time. and for the pressure switch just run your main power to one side of the switch and run your compressor to the other side. i hope this helps ya
