Got in the coach today,2 full accelerator presses,turn the key and she starts up on choke perfect. Then I notice No compressor sounds! Lucky I always have my double 4x4's in place and its not on the floor. Could it be gone?Seems like fuses are good. Where is a good starting place to troubleshoot?

I would check the solenoid leading to the pump motor. Mine failed over a
winter of sitting for a while.

Get a Voltmeter or a simple test light. Start at the compressor motor and work backwards through the pressure cut-off switch, relays, main breaker control switches etc. till you find the break in your power.
I would suspect the pressure cut off switch.

Iff your airpump is in the cabinet and the fuses just above it is easy to set up a wire direkt from the fuses to the pump to see if it works

When looking for faults, always look for those faults that are easiest to get at, first
