Air pressure switch adjustment
The 110v air compressor in my coach would come on at 70psi and cut off at 100psi. I thought this was too low since the door, generator slide, etc. were slow to operate. Today I adjusted the pressure switch to come on at 90psi and cut off at 118psi. I made an adapter with a piece of 1/4" air line and added a quick connect on the other end. I dumped all of the air out of the coach system and removed the air line from the pressure switch. I attached the adapter then plugged the other end into my portable shop compressor. I was then able to use the regulator to see where the start/cut off settings were while I adjusted the 2 screws on the pressure switch. Worked out pretty good.
