My battery will only charge when coach is running. Charges up to 13.8 volts dc. when i shut coach down the battery looses it's power rapidly within a few hours. When I plug into shore power the same issues. I don't know how to figure out if it's the battery or the converter/charger. The model is a MagneTek 900 series not sure what one. The coach battery is brand new. The secondary battery is about a year old. Any help would be greatly appreciated
Which one are you talking about?
Coach battery is the one in a compartment that the converter charges when stationery and plugged into shore power.
Chassie battery is under the hood.
Sounds like your converter is not working properly to charge it after you park and/or you have a bad coach battery.
Put a tester on the converter and hold it there for a few minutes to see if it reaches where it should be or not or exceeds it.
