Sorry, but this is a double post in 40/55 and 60 section. 
Just installed my ARB Compressor. Testing it, the pump will not shut off until I actuate the Locker switch. The compressor will keep running with air blowing out the purge vent on the Solenoid (red arrow) ...
When I actuate the Locker switch, the Compressor will fill in 5 seconds and stop. The system will hold pressure for 15 mins without compressor cycling.
Isn't the compressor - without Locker activated - supposed to fill and stop?
I've triple-checked all wiring. Only have rear locker.
