Thor Tellaro Batteries not Charging
Hello - I have a 2021 Tellaro KT with the standard AGM batteries. We are on a 2 week trip through the southwest and the batteries have stopped charging via the engine alternator and generator. I do get a slow trickle charge via the solar panels. With just the frig running the mornings start off with about 12.1v and below about 10ah. By late in the day (if sunny all day) will be at about 12.6v and around 60ah. Thatís after driving all day thus I know it should be much better than that. With the engine running I do see the chassis battery is charging as the battery voltage is around 14.2v, but the couch battery remains at around 12.5v. With the generator running I can bump the coach battery up to around 13.3v but several hours of it running does not boost the available amp hours. Based on all this it appears only the juice from the solar panel is actually making it to the batteries.
Does anybody have any idea what is going on? I suspect there is a bad gizmo somewhere that is keeping power from making it from the alternator or generator to the batteries. Iíve checked all the fuses and have done a complete shut down and restart but still having the problem.
