battery disconnect switch and ac power

i hope this is not a new one for anyone! i have a 2008 four winds chateau model 31f. when i am parked for extended periods i flip the rocker switch that disconnects the deep cycle batteries. i do this to not overcharge them. just left on a trip and flipped the switch back to connected and all was ok. drove 1500 miles, parked , plugged in the 30 amp ac, flipped the switch to disconnect and guess what? no ac power. kept flipping the switch and finally got ac power. then later it seems to go out again. even the converter will not supply the dc powered items. flip the switch back to connected and all is well. been good for a week now. thing is, i am parked for 2 month's and don't want the batteries cooking away. why is this dc connected to the ac? been a mechanic all my life but this is a new one for me...... help! thanks, gary

If the batteries get too low on charge the switch will not change over

If your converter is smart it wont cook your batteries therefore flipping the disconnect is unnecessary.

i did have that problem 2 years ago with the batt volt too low and not switching..... guess my convertor is not too smart as the battery voltage is 13.8 volts batteries are cool still but that is too high i believe. thanks for the help so far, gary

My 02

In my rig the battery disconnect is purely DC and has no connection to AC power - can't see any reason why the two should interface - think you have a different problem than your battery disconnect switch.

Your not cooking your batteries when your hooked into shore power. Older converters simply put out a constant voltage which overtime would result in lowering the water in the batteries - so long as you occasionally added water your batteries did OK. Newer converters are considered "smart" and the voltage will be higher on the front end (quicker charging) and once the battery has been adequately charged the voltage drops to mitigate loss of water.

When AC goes out I first check the circuit breakers - then the campground pedestal. Most rigs have at least two GFI circuit breakers (bathroom and kitchen) which should be checked (anything on that circuit will go out when the breaker triggers).
Loose wire etc?

Lastly - if by AC you mean air conditioner then you should note that the air conditioner won't work unless the thermostat is being supplied DC - depending on how your rigs wired disconnecting the batteries would disable the air conditioner.

Hope this helps.
