I don’t know about the particular Blue Sea switch model number, but I had an electrician install a Blue Sea system battery management switch on my previous boat (also a 34). The Blue Sea switch had three separate switches, one for the house, one for the starter, and an an emergency crossover switch to be able to use the house bank to start the engine if needed. I had two house batteries and one starter battery. Because the boat came with the old 1-2-all Perko switch, I decided to leave it in place to control the house batteries. When the Blue Sea house switch was off, there was no power to the house. When the Blue Sea house switch was on, I could then use the Perko switch to control whether to use house #1, house #2, or both. The starting battery was separately controlled by the Blue Sea starting switch. When it was on, I could start the engine. When it was off, I could not. I never needed to use the emergency crossover.
I also had battery combiners that would combine the batteries while charging, then isolate them when charging stopped. I liked the system so much that I bought the same Blue Sea switch (newer model) for my current boat. It has been sitting in a box for a couple years now, waiting for me to get to this project.

Align the engine and do the wiring. This is question about the wiring for people who have the same Blue Sea kit. To manage the batteries we are using the Blue Sea Dual Circuit Plus 5511e switch and the 7610 ACR. Although we already had the ACR these two combined are what Blue Sea call the Add A Battery Kit. Both of these are connected correctly but the behaviour seems wrong to us. When we set the 5511e to 'Off" it turns only one of the batteries off. In our case it leaves the house battery connected through the switch and disconnects the starter battery. Using and ohm meter with the batteries disconnected we have found that in the 'Off' position only one side of the switch is closed and the other open. So it is the switch doing this, not some bad wiring going to the house. This seems like a faulty switch to us. Here is the catch. We contacted the company that sold us the switch and installed it, Gartside, and they said that is the way it is supposed to work. It should only turn off the starter battery. I have looked at all the Blue Sea material and this seems wrong to me, according to the literature, but it never specifically says what is done in the 'off' position, but it certainly seems to imply that both sides should be turned on and off simultaneously. It also has a combined mode, but that is a separate thing. Does anyone else have this setup and how does yours work.
