Sorry for all the stupid questions, but I do not know how else to learn.
Believe me, no questions are “stupid”. We have all been there. Yes the generator (as well as shore power) should recharge your house batteries as long as the Use/store switch is in the Use position. In many Thor models, (those equipped with a BIRD/Trombetta or BCC), the chassis battery is charged at the same time and the coach batteries are charged by the engine alternator as you run down the road as well. I don’t know if your coach is so equipped.
When you store the coach, there is enough ambient voltage to run down your batteries even with the Use/Store in the Store position. On most (I believe all) Thor coaches there is a 50 or 100 amp circuit breaker inside the battery box which completely disconnects the coach batteries. It has a red (usually) button which, when pushed releases a red or yellow “flag” showing that the batteries have been disconnected. You push the flag back in to reconnect them. There is a similar device for the engine batteries in the engine compartment. Most do not disconnect the engine battery because it shuts down the engine computer. If you do not have one, an inexpensive voltage meter is a must for keeping up with the electrical issues you will encounter. Ed’s manual is absolutely essential (even if it is for the Axis/Vegas many of the systems and equipment is similar). And you should search out the location of all the fuse boxes, and how the electrical system operates. It will come in handy when you have electrical issues on the road.
