Also turn on the Battery Merge switch on the driver panel - this can be left while plugged in to connect the house/coach batteries together but should be turned OFF while driving so the engine alternator is not trying to charge all of the batteries - the alternator should only charge the engine batteries. Ours has a 3-position switch - the middle selection is OFF and UP connects the coach/house batteries. The generator will charge the batteries but it is slow as there is usually only a small alternator as far as I know but maybe some of the others can chime in on generator function. You might want to check the voltage in EACH of the batteries by disconnecting them (I know, it’s a pain). If you find one that is under voltage or dead then you should probably replace the whole BANK of batteries so the old ones don’t kill the new one…
