Monaco Dynasty jack issue

Valid is the JACK control system. The Jacks should be HWH. Valid is a Air/Hydraulic option control system for hi line Motorhomes with air bags and HYD jacks. Valid also makes controls for hi line Air BAG ONLY leveling and driving systems. Odds are the battery heavy cable for the HYD pump are not secure or corroded/loose connections. I don't like to hear "I just replaced the batteries a few months ago". WHO CARES? They could still be either bad or you have let them discharge to a too low rate or your Inverter/Charger is not doing its job to keep the batteries up. Use that link the other poster posted for how to gauge battery state from the battery voltage. ALWAYS use a handheld Multi-tester to take measurements. Do NOT rely on the onboard volt meters. Verify the battery cable connections at the HYD pump are secure and not loose. Same at the Batteries themselves. Doug
