Are you talking abut the switch? I would like to get the ACR but, didn't know that automate the charging but was trying to keep things simple.@jgn1013 It only has three studs on the back of it? Mine had 4. Perhaps different model? Are you also getting the ACR with it to automate the charging of both batteries?
Do you have a wiring diagram available? I just want to be able to run stereo without worrying about not being able to start the boat later in the day.Yes. I see it is a different model than what I have.

Anyhow, you diagram appears correct for that switch. I would add buss bars, if you are so inclined to clean it all up.
Preferably though I would personally not use that switch. I would isolate my cranking and bilge on battery 1 and then house and everything else on battery 2 and use the switch and ACR that I linked. Which is what I did. I don't know your specific use case. That way I could split the draws on the batteries and combine them when needed. Different scenario's for different purposes.
Thanks again for the help. I'm OK with just moving the switch over to 2 when I dock in the cove. KISS@jgn1013 I do for my setup, I use the switch I linked. In your scenario you are drawing the stereo and other things either off of 1st battery or second battery or both, but you have to switch to make that happen. In my scenario I am always drawing engines and bilge off of First Battery, and the Stereo and other electronics are always drawing off Second Battery, The only time I would ever combine mine is in an emergency. So I turn my switch on and off I go for the day. The ACR alternates charging between the batteries. Below is what I did. You can see the busbars which clean up the positive and negative. Optimally this is the way you want to do it so you have a dedicated Starting Battery and a Dedicated House Battery, each doing their own thing, but can be combined in an emergency.

In your scenario you would have to switch it every time with that switch or leave it on combined all the time, which is not recommended. Your switch is different and can't be wired the way I use mine. Your wiring diagram for your switch works. But everything will either be pulling on Battery 1 or Battery 2 or Both in combined mode.
