Riviera dual shore power question

[SunsetSteve]

Thanks for the inputs, guys. Will be sure to follow - couldn't fill the water yesterday because no tool to open the access port. Going back tomorrow to try again.
But I am still not clear as to whether I need to have the battery switch to "1" to have the charger charge Battery 1 while away. My previous boat had an ACR so I didn't have to think about it.

No one will be able to definitively answer the battery charger question because they can all be connected differently.

Once you get the charger fired up and running, check the battery voltage (and it should be between 12.8 and 14.2 roughly, but NOT 12.6 or lower. Then turn the main switch to "OFF" and see if the battery voltage is the same, or if it dropped. If it dropped, then turn the battery switch to #1 and retest the voltage, then switch to #2 and check the voltage.

Ideally, the charger should be connected directly to the battery (ies), so that the battery switch could be in any position and the charger still would charge the batteries, but not everybody wires them that way.

Qr Bbpost..... Ideally, the charger should be connected directly to the battery (ies), so that the battery switch could be in any position and the charger still would charge the batteries.....

Ideally, the charge wires should be connected to the source side of the battery switches or direct buss bars. These are a direct path to the battery/bank and doesn't matter what position the switch is in. It's best to hook them up at the switch because it keeps the number of wires at the batteries to a minimum witch is ideal. Except for perhaps a charger's temp probe, the only wiring that should be hooked up to batteries are the primary battery cables and nothing else. These should lead to buss bars from where they branch off to everything from the house loads to engines.
