When trouble shooting your system when it is acting irratically but mainly not at all. Follow Equalizer Systems trouble shooting instructions but one thing you can add is proper grounding.
Once you are under the coach Clean all connections and check each one, I used electrical contact cleaner from NAPA and air blow each one dry. You will also notice that all the system ground wires ground to the pump. Pump then becomes the chassis ground when bolted to the frame.
Tighten the two bolts to ensure a good ground. Loosenes the nuts and use de-greeser under the pump to remove oil and ensure a good ground.
This solved my problem of intermittent opperation and strange things happening with the system. Keep this in mind next time you have Equalizer System problems.
