With the current FR wiring on the 378ts the battery on/off light is very misleading. If you operate the battery on/off switch to disconnect the battery from the load, with no 110AC shore power, the battery light goes out. However if you connect to shore power now under this situation the battery light will come on giving the impression that the batteries are connected to the load and are being charged.
The attached schematics show the current and proposed wiring.
My question, does anyone see a problem with this change ??
