The compressor will not come on with the dash rocker switch. I can make it run by pushing on the pressure switch. BUT it shuts down quickly.
MY best guess is the rocker switch? IDEAS?

I've been told to look for the simple first. Check the fuse or ckt breaker protecting the the compressor before the switch. I f you have power on both sides of the fuse or ckt breaker, time to do the same with the switch.
Enjoy your your new hobby !

Sounds like it might be a faulty pressure switch. Check to see if power is available at the pressure switch in both positions of the rocker switch. If so the rocker switch is also faulty. It should disrupt power in the off position. The pressure switch should pass power to the compressor at +/- 70 psi then disrupt power at +/- 90 psi. It will not re-enegize power until system pressure drops below the +/- 70 psi start up.

Pretty sure that pressure switch is set to start compressor at about 70 psi. Rocker switch only allows power to pressure switch which turns on compressor.
Nothing will happen till main tanks fall below 70 psi.
