The problem is that currently my solenoid appears to be releasing to much pressure (much more noise than unsual) so much that once it releases pressure the pump goes back on and this cycle continues. This seems to be a new development after recently bringing it out of storage. I have released the moisture in the system with no change in the operation. I know there is a low and high pressure switch on the wiring scheme but I'm not sure how to check for proper operation of pressure switches and solenoid? Any suggestions, Mr. D.

The air can bleed back thru the compressor when it shuts off, when the small check valve goes bad.
Replacing the check valve stops that problem.
It's a small brass check valve that can be near the compressor, or under the coach, near the air bags.
