house power

[madmax]

Hi,
I'd love some advice on house batteries. It's been discussed extensively, but I am new to RVing. Last night, while being plugged into AC, we lost all 12 Volt power for the 'house' (ie lights, water pump, fans etc. I didn't think it was possible while being plugged in? My RV is nine years old and who knows how old the batteries are. They are the sealed type. I am also wondering if the power loss could have something to do with the converter?
Any help or advice would be greatly appreciated.
Thanks,

We've had two class A's that have battery disconnects by the step. Off or on, the converter has powered 12v requirements....

I like my lifeline agm batteries. they have much higher capacity than other brands that would fit in my battery compartment. 300ah vs 200ah.
lifeline agm batteries are sealed and can be mounted upside down if desired. they are constructed like aircraft batteries.
i mounted mine on their sides for clearance.
i got them from bd batteries online.
my house battery switch is in the stairwell also.

madmax, it sounds like you lost the battery charging circuit and the batteries ran down. You will want to check the 120 circuit breaker feeding the battery charger and any 12 volt fuses on the output of the charger. It could be part of what is commonly called the converter where AC and DC over curent protection is housed or it could be a stand alone charger. Once you get the charger issue fixed then you should test or have the batteries tested. If you find you need batteries then we can help if we know how you use your coach most of the time. Do you boondock a lot with out power or go to campgrounds and are always plugged in?

MY guess is that it is the battery cutoff switch in the entryway. I have a 2004 Monaco Lapalma, and have had this problem three times. The dealer replaced a selinoid behind the fuse panel in the passenger side front compartment. The last time I just bypassed the selinoid and have had no more problems.

The most likely explanation is that somebody hit the Battery Disconnect Switch to OFF. Next one is that the circuit breaker to the converter/charger opened (or possibly a GFCI, if it is on a GFCI circuit) and the batteries were not able to supply enough power for your needs.

Was it a sudden loss or did the power gradually fail, i.e. lights get dimmer and dimmer?
