If this is the switch you have: https://www.bluesea.com/products/5511e/e-Series_Dual_Circuit_Plus_Battery_Switch
then Off - should disconnect both battery ( banks ) ie no starter to engine and no house to boat On - should connect starter to engine, house to boat but keep the separate Combine - should combine the starter and house battery and connect them both to the engine and boat > It should only turn off the starter battery. No, the documentation clearly states "Simultaneously switches two isolated battery banks". It is strange to have a defective switch and an installer that thinks it suppose to work that way. Michael Brown Windburn C&C 30-1 Date: Sun, 8 Apr 2018 10:40:49 -0600 (MDT) From: DON JONSSON <dbjons...@shaw.ca> Hello Last year when we installed a new engine we had the local mechanic do two things. 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. Thanks Don Andante, C&C 34 Victoria, BC
