Power problems

[Philwendy]

I have a 2005 25FDS my battery will not stay charged when the trailer is connected to 110 power 30AMP service unless I have a battery charger connected directly to the battery. I have a new battery installed. Any ideas or direction in wish to check all c/b are closed and all fuses are good???

Sounds like Converter is defective or has power supply 115 VAC or output 13.6 volt DC breaker open or fuse blown. What is voltage at battery with AC on and charger charger not connected? That is the add on BC. It should read 13.2-13.6 with the converter on line. If only 12.+ its not being charged.
Theres a ac circuit breaker in the main panel for the converter supply. There are fuses on the converter one end. Also there is a 12VDC in line fuse usually near the battery in wire from converter. Any open can cause this.

I agree. If there are no tripped breakers (including the inline resettable breaker between the battery positive post and the converter) and if all fuses are good, then your next best step is to check the output voltage from the converter. Your converter's manual will explain how to so that. Check the Files section above if you don't have your converter's manual. We probably have it there.
