I have a 2010 Pleasure-Way, Ford E-350 chassis. Recently, I plugged in the shore power cable to make sure the coach battery is fully charged and left it plugged in overnight. This morning, I unplugged it, checked the battery level, and it went immediately to zero. I put a meter on the battery and it shows 11.8 volts, falling off to about 11.7. Nothing in the coach works, so I'm wondering if there is a problem with the inverter?Any information helpful before I have to take it to the local repair place and spend my life savings.

There could be a problem with the CONverter. You'd have to put a meter on that. Assuming it's a flooded battery, have you checked the water?

x2 start at the battery pull out clean check water charge over night ,should read in the high 12v range even over 13teen on a good battery.

What voltage are you getting at the batteries when plugged in to shore power It should be at least 12.9 or better if your batteries are reading that low. If your not getting this you need to find your inviter (takes 12 volts and makes 120 volts)/ charger. Or your converter(takes 120 volts and makes 12 volts)/charger. And see if it is putting out power to the Battery charge wire, it could be anything like a blown fuse on the converter or inverter. Or it could be the converter or inverter is not even getting power, breaker tripped in the rv breaker box to the converter.

Do you have a battery switch? Need to select in-use or on position to connect the battery to the charging system. I don't think the batteries charged at all. At 11.8 volts the lights should still work... unless the battery is disconnected.
