Note I read this here: The RV Battery Charging Puzzle « HandyBob's Blog
just not sure where to start at all
Thursday night plugged the trailer into shore power at home. Fri around 5pm disconnected and it showed a full charge (4 lights). Note I might have looked while it was still connected. Looks like it might always show 4 lights when it is charging.
Towed the trailer 100 mi for an two night, no hookup stay. Very light use of lights, pump, ran the furnace maybe 5 minutes in the morning. We were literally out all day and didn't spend much time in the trailer.
Sat 10pm we were out out. Lights dim, pump erratic.
I have a 2012 Surveyor Sport 189 with two 70AH batteries. Where do I start, with a battery monitor?
