Because, people have SHORT memories. When the season starts back up, they sometimes forget about the 120 side of the water heater and then accidently dry fire and destroys the 120 element. ESPECIALLY if they have the water heater bypass valves where NO water goes to the water heater tank and when they open the faucets and see water out of the Hot and Cold, they assume the tank is full of water. By leaving the drain plug removed and the wire harness disconnected, they cannot dry fire without actually going to the outside of the water heater and reconnecting the harness and installing the drain plug and that is enough to make sure the tank will fill with water.

Provided they remember to swap valving on water heater so it is no longer bypassed.

The batteries stay in and it stays plugged in 24/7/365 so the Progressive Dynamics converter keeps the batteries charged. I do not disconnect the battery. I have killed chassis batteries by not doing that.

Yes, but the EASY thing to do is just disconnect the wire harness plug at the ignition/control module. That is what we do on our winterizing at the shop. Doug
