I am having a problem with my 12 volt system. Rignt now it uses battery life and when the battery gets down to 25% or so only 1/2 half of the ceiling lights work. The coach is plugged into a 30 amp plug with only one AC working due to lack of 50 amp at the campground. Per techs at Lazy Days and Ocean Grove RV, I checked the power input, pole out put, shore cable, all fuzes, including all fuzed in the front compartment. All voltage was OK. I inadvertedly turned off the main power switch and turned it back on again and everything worked OK. However, it keeps occuring and I am having to "reset" the main power switch about every 8 hours. Any ideas?? Tried calling Crossroads and was on hold for 2 1/2 hours on 5 July, left 2 messages, and have not yet received a call back. Any recommendations would be helpful
Thanks
John

By "main power switch" I assume you are referring to the main AC breaker in the coach? If so it might be a bad AC breaker, however the resetting is confusing as to why that works for a while.

I am resetting the main battery on/off switch located below all the hydraulic cables and adjacent to the batteries

Yes and that seems to reset something and all works well for 6 to 8 hours then I have to reset again.

Don't understand why that would make a difference. If the gage for the battery is going to 25% when plugged into shore power, then the converter is not supplying 12 volts to battery. The battery usually shows full charge when plugged into shore power.In normal operation, you should be able to have 12 volts from the converter to coach lights and etc. even when the battery switch is off. it just won't charge the batteries. Just went down to the RV, checked mine, and sure enough the lights work with the battery switch off. Maybe something wrong with the converter or a resettable breaker somewhere.

By the way, you don't remember me but we met in Sioux Falls, SD last spring at the KOA. We were there parked by you in our Montana and being Redwood wantabees we hung around until you and Sam graciously gave us a tour. Thanks again.

If that is so maybe theres not enough power. Check one of your outlets to see what the voltage is. Meaning that the AC is sucking up most of the power and the converter is not able to keep up with the charging of the batteries with the all the 12 volt lights on. Have you tried to turn off most of the 12 volt lights and run the 110 lights to let the batteries charge up? Really sounds like your converter is not keeping up? Just a thought.

John, just curious, but have you checked the water levels in your batteries? They might be low.

Just check mine and it is the same as your’s. So that means that it runs off the inverter when plug into shore power. I have 12v batteries that are "maintenance free" so you cant check the water level. Have you checked you fuse panels?

Folks we checked all fuze panels, fuzes, breakers, ran continuity test on shore power cable, etc. I am kinda thinking that Bruce might have a point that the when the single AC is running at full blast there is not enough juice to support battery charge. That however brings up another thought as to why that would occur as I have had this coach in my driveway with only 110V for normal cleaning etc and the battery charged and all other stuff (did not turn on any AC) worked fine. Also wondering if converter is going bad and how in the hell do I check that??
