Will this work?
I have a single battery setup. I am adding an amp (2 total) I want to have all the audio stuff on one battery and everything else on the other.
My plan: add another single battery shut off switch for the audio and put the battery doctor isolator on to help keep the audio battery up while we are out. Am I over looking something?'18 mojo

There is a ON/OFF dual bank switch that turns both banks on or off with the turn of one switch, This would replace the existing single bank ON/OFF.
A 1/2/BOTH switch is an even simpler setup, but requires some manual input from the captain, when dropping anchor and returning back to running. But it accomplishes the same thing. One bank for house loads at anchor and one bank for running.

What type of fuse should be used between the batteries and the acr? Will a 250amp fuse like the ones used between battery and amp work?

Im a breaker man, myself. Amperage needs to be based on the amp load passing through the system and the cable gauge used. Cable gauge also needs to be sufficient for the load.

I added the blue sea si acr. Can I hook a battery charger to one of the batteries with the system all hooked up? I put it all together and have the led flashing that the acc battery isn't charged enough. I'm assuming this is ok but wanted to double check since I have 2 batteries on the system now

ON = charge is passing through the ACR to the house bank
OFF = banks are isolated
Blinking slow = SI
Blinking Fast - one or both banks or VERY low, below 9.5V

The led light was blinking fast BUT it turns out I had a wire grouped incorrectly. Once I corrected my mistake the blinking stopped and everything worked correctly again.
I have a small portable car charger I use. I'm assuming that if the switch is in the off position and I hook the charger to one battery the acr will transfer the charge into the second battery as well? If this is correct are there any issue in doing this?'18 mojo

Riddle me this...
Hooked up the acr about a month ago. I hooked the boat to the fake a lake and started it in the driveway to make sure everything is working as it should b4 we get on the water.
ACR in the on position:
Turn key to acc position and the raido works
Turn key on and start boat, the raido goes off
ACR in combined position
Raido works in all key positions
ACR in combined position
Boat started then acr turned to "on" position and raido stays on.
I do have 2 different size batteries that have been recently charged
Stereo hooked to 24dc-1
Everything else hooked to factory interstate battery.
Is this a battery mismatch issue or do I have wiring screwed up somewhere? I wired it according to the illustration on the blue sea site.'18 mojo
