Damn. Your setup is impressive. I don’t have the knowledge to do all of that. I just wanted a cleaner install. Both of my batteries were just laying there right in the middle of the storage compartment, no battery boxes or anything. Now I’ll have a bit more storage space

I didn't know much about a week or so ago, but I scoured the threads here, asked a few questions and did a bunch of reading. Once it all clicked it really turned out quite simple. It was the initial layout and design that wasn't simple going into it. Then I drew a schematic and sourced the parts.

The design is not mine, it is a copy of those on here who are far smarter than I.

I took the majority of my inspiration from this post and diagram, which really made it much clearer by @0627Devildog Then I did a diagram to suit my needs and accessories.

Looks like everything is working now. The way I had it originally wired was good. The reason why I was having issues starting the engines were some disconnected wires behind the helm. Everything works now. Thank you to everything that helped me with this issue.

@Av8tor07 On mine I have a bilge wire which is always hot so that goes on my starting battery post. Also if you are using the ACR you need to add the ground wire with a 10 amp fuse as recommend to the connector at the bottom front of the ACR.

I have two bilge pumps and I wire those directly to the batteries. I keep them separate.

@Av8tor07 I didn't wire anything right down on the battery, just the four cables, 2 positive and 2 negative for them. But by putting them on the same post on the switch, it is just the same thing. The cleaner way is to use another Buss Bar, but I ran out of room. Plus it feels cleaner if my starting battery goes down that by combining on the switch will fire up the bilge pumps. Although in theory I guess it would work the same if on the battery terminal, just feels a bit more convoluted to me. Plus it is something that doesn't need to be remember when switching or pulling batteries.

You really aren't keeping them separate in the system, just the location of tie is separate.

@Av8tor07 I just got off the phone with Blue Seas Tech support, was asking some questions and validating something. With respect to the ground fuse, he indicated that they DO NOW RECOMMEND 1 amp fuses. The documentation that I linked is no longer current. He predicts that typical voltage going through the wire will be 20 milliamps. He also said for those that do have the 10 amp breaker it is not a big deal but if you can change it do so, which I will be doing.

How are you charging the additional batteries once installed, or is that current setup include that?

I placed a 10 amp fuse but I’ll replace it with a 1 amp. Thank you.

I do have a smart 2 bank charger attached to both batteries. I can’t plug in the boat at the place where I dry dock. So the point of the ACR was to charge both batteries simultaneously while the engines are running.

For the trolling motor, they are isolated from this and not tied in. NOCOgen5 4 bank charger, one for each battery. So all 4 batteries can be shore charged. 10 amps per bank

Got it...same for the tabs?
