Battery switch confusion

I just bought a new Caravelle Sea Hawk with dual batteries. The battery setup doesn't seem right to me. In my old boat with dual batteries, when the Perko battery switch was "OFF", then all boat power was off except for the bilge pump. On this new boat, I can start the motor and operate the boat motor (Yamaha) with the Perko switch in the "OFF" position. The remaing boat power (lights, elctronics, etc.) is only on when the Perko switch is in the "1", "2" or "ALL" postion. Also, there are a couple more wires attached to the battery that I don't understand. My questions to you folks are as follows: <br /><br />Does this seem right to you folks? Is this some new wiring option that prevents excessive battery draining? Could it be mis-wired? <br /><br />I'd surely appreciate your responses. <br /><br />Thanks!

Re: Battery switch confusion

Sounds like it is not wired correctly - off means off, except for bilge pump(s). The battery switch is just a collection of the positive wires from the batteries and to the starter(s) and positive bus(es). There is also a constant on terminal (if I recall correctly). Sounds like the positive wire going to your starter is wired to this terminal, or one of the input terminal from the batteries.

Hi Rocky, welcome to the board. :) <br /><br />There is no right or wrong way to wire a battery switch, lots of thoughts and opinions on how best to do it. Personally, I like the way your other boat was wired; to me “off” means “everything off”, i.e. the battery is isolated.

Re: Battery switch confusion

I'm with 18rabbit on this one. Wire it the way you want it :) <br />I prefer to have it wired like your old boat was. Off means off but keep power to the bilge pump(s) full time. I have 3 batteries; <br />#1 is my single start battery.<br />#2 is my 2 x 6v house batteries.<br />I run on both, switch to #2 when I'm anchored and save my start battery for when I need it.

Re: Battery switch confusion

I have your present set up, engine and bilge is always on. Reason being bilge pump needs to work even when no one is aboard. The engine is wired direct to the battery so you can't damage the rectifier (?) on the outboard if you switch to off by accident when your engine is running. At worst it will only give you a flat battery.

Re: Battery switch confusion

Some of the extra wires might be the engine tilt/trim, mine was hard-wired to the battery too, just followed them back to the tilt/trim motor.<br /><br />And I agree... off should mean off
