If everything is working properly, leaving your coach plugged in should be no problem. But that’s a big “IF” in the Axis and Ace. The converter/charger that Thor installs is not reliable. If you get a good one, it seems to work. If you get a bad one, it doesn’t. I have had two “bad” ones in my Vegas and Axis and have replaced one. It is easy to check. Run the batteries down below 11.6v. Then plug in the coach and read the voltage. It should read around 14v, give or take a tenth. It is on high charge. After a day, it should read around 13.5V (normal Charge. After the coach has been plugged in for a few days, check the voltage on the batteries again - they should read around 13.1V (to keep the batteries topped off). If the charger does not go down to 13.1, you have a bad one and leaving it plugged in continuously could boil or dry out your batteries and shorten their life or even kill them. Also Your Ace should charge both sets of batteries (coach and chassis) on generator, shore power or engine. If not you have a problem with your BCC ( battery control center) or BIRD/Trombetta, whichever you have.
