Mysterious Beep '05 Monaco Cayman
First trip in my 2005 Monaco Cayman 33' (300 Cummins). On long climbs, a beeper will start sounding without any associated warning lights. It is the same beeper that sounds when you first turn on the ignition, but goes away after engine start. I called Monaco tech support and they said that it was low hydraulic fluid in the leveling jacks reservoir. Filled reservoir, same thing. Called them back, they said if it wasn't the leveling jacks then it was probably an air leak in the suspension. No leaks detected by an RV mechanic. He said that he remembered something about a Monaco recall concerning a spurious beeper around that year that entailed disconnecting a wire to the beeper, but was not sure. It only happens on a long uphill stretch and stops when I level off or go downhill. I thought it might be the temperature, but it happened again in a cooler area when the engine temp was 20 degrees cooler on the climb. By the way, I checked the coolant reservoir too.
