Blue Sea Systems used to have a simpler switch to separate the house and engine batteries (or combine them if the starting battery failed to start the engine). This is the setup I had on my 34. I kept the old Perko 1-2-all switch for the two house bank batteries, although I usually kept that switch on “all.”

Is this just to prevent the good batteries from being drained by the bad one(s)? So if I had multiple house (or start) batteries, I could just additional on/off switches linked to a house or start bus, and a switch between the buses? Something to consider depending on how far I get carried away with my electrical. Currently I have 2 banks, with room for a 3rd, and just leave them combined all the time, as they are all 6V GC batteries. If I'm concerned, I could isolate one bank in case the sun stays away for too long (and we're not motoring at all), but so far that hasn't happened. And so far, the only significant load we have is the fridge, with minimal electronics. Once we add radar, that will change... -- Shawn Wright shawngwri...@gmail.com S/V Callisto, 1974 C&C 35 https://www.facebook.com/SVCallisto On Mon, Nov 18, 2019 at 1:56 PM Josh Muckley via CnC-List <cnc-list@cnc-list.com> wrote: I suggest changing to the linked setup. https://drive.google.com/file/d/1T4WnvplsWG_o9r6drc-FnhbTo0TJ4E_-/view?usp=drivesdk Take this opportunity to do away with the 1-ALL-2 switch.

Seems this is a common problem base on this forum: https://www.thehulltruth.com/boating-forum/853223-blue-sea-battery-switch-failure.html I emailed Blue Sea and await their response. Four years ago I replaced the original old Perko switch when I did a battery upgrade/rewire/shunt+monitor. Now I’m worried about simply replacing with the same one if it’s prone to failure. Luckily this happened at the dock but it could have been really bad if I’d needed power in a hurry. I’m now thinking I’ll wire up a “backup” bypass directly to the starter in case this happens again or for jump starting, etc. Any thoughts on this from the collective wisdoms of this list?
