DC electrical failure

I am having a problem on my 2003 Monaco Signature. When I unlug from shore power, about two minutes later I lose all electrical power. I've had new house batteries installed and all the cables and connections cleaned in the battery bay. Everything seemed OK for a few days but now its doing the same thing again. Also then, even when I plug back into shore power, I cant get lights, slides, etc to work until I cycle the ignition key to run and the inverter boots up. Anyone have any ideas???

Maybe the converter is not working so batteries are not charging and now the new batteries are dead or the relay that connects alternator to house batteries not functional?

I agree, it sounds like the charger is not working.

There is a switch by your front door that turns off 12vdc. It controls a solenoid which has no other purpose. Best to locate this and bypass it. Not sure where the solenoid is in your coach. On mine it is in the front run bay but I think yours may be somewhere in the rear. There will be a large cable on each side that go to the batteries and the smaller terminals will be the control wires from the switch. If the large cables are long enough, remove one and attach it to the other terminal. Then remove the control wires and tape or insulate them from each other and anything else.

The solenoid is know to fail and is not needed except for the switch by the front door to turn off the DC. You have a battery cut-off switch that will also do that in your battery compartment.

Batteries are fully charged.....checked with the Aladin system, the inverter remote panel (moves to float charge) and by putting voltmeter on the batteries themselves. Also there is no loss of voltage at the batteries when I unhook from shore power or during or after power loss.

If you lose 12v power, lots of things that are seemingly powered by 120vac will stop working. That's because circuit boards, relays and even the thermostat for the air conditioners is driven on 12v. My best guess is that your charger is not working, or a fuse has blown that prevents the charger from replenishing the batteries. That's why it took a couple days for the problem to re-appear.

12 volt electrical problem

Just to let you all know.... I took my coach to a reputable service dealer who checked the batteries, solenoid, inverter/charger systems etc...determined that the battery cutoff switch in the battery compartment was faulty ...replaced it and everything is now ok

All I can say about that is: Man do I know that problem (I fixed mine myself though, Faster (no waiting for parts) and less costly (Total of $0.00 in this case)
