ACR setup question

[sailpcb]

Hello. I’m redoing the mess of an electrical system starting with battery setup. I’d like to get an opinion on how I’ve laid this out, and any improvements or cautions are appreciated. My engin is a Beta Marine 60 with the starter/Alt coming from one output bolt. Thanks!

this is what I used to do mine, it is pretty straight forward with this diagram.
Hope this helps

Welcome @sailpcb to the forum.
I like the ACR part of the above pictorial wiring diagram by @fred1diver . The ACR has to positive leads that connect to the batteries. "Automatically combines batteries during charging, isolates batteries when discharging and when starting engines".

If the switch to your house bank is off, the ACR won't work.

Thanks for the schematic, I’ve decided to replace the ALT wire so that it can go directly to my house batteries while the starter can go to the starter battery, my first sketch is bad. I’ll be able to configure a better setup with the separation of starter/alt wiring found on Beta Marine engines.

Don't forget to fuse your ACR
