Guys I'm new to this website and thought I'd seek advice on the electrical project on my 26' cabin cruiser that I'm planning.Here's the situation: I have a two battery system that is currently in parallel w/ a factory installed 1-2-off-both switch.
I installed a windlass and connected to the positive terminal on one of the existing batteries. I've found that I have drained the power down overnight after anchoring up, running the stereo, refrig, etc. Most of the time I remember to keep the switch on 1 or 2 and keep one battery in reserve for engine cranking in the morning.
What I want to do is install 3rd battery which powers the windlass, stays fully charged, and can be used to parallel the existing two battery system at my discretion. This way if I forget and leave the battery switch in the "both" position and draw both down then in the morning I can manually flip a switch and have 3rd battery back-up power to crank the engine.
Any good advice on: 1. Battery Selection 2. ACR 3. Switch 4. Wiring Diagram
I've looked at the BlueSea.com website, studied the info at WestMarine but am still a bit confused on how to rig this up.
Thanks,
