My next project is to re-wiring my bilge pumps, install battery trays and just perform a little house keeping on my battery bank. It would appear that it has been DIY'ed a few times. My question to the community, especially if its similar to mine; how does you're battery bank look? Wired? currently my system is 3-Deep Cycle batteries (27, 24, 4 group). I have solar as well, not sure where it goes, i.e. which battery is being charge. I can't trace back to what battery is being used as a starter/crank. I think two batteries are wired in series. So I would like to make it nice and neat and more manageable. Thoughts?

As for my bilge pump, existing, there is NO float switches for my three engine compartment bilges. The bilges switch are manual, and located under the salon floor. So, my project is to installed three NEW bilge switch (S1, S2, S3,) some where in the salon. Install three new float switches, and I want it to be wired to one common buss that runs all the bilges. See my one line diagram. I believe its a solid layout/design. If anyone has thoughts or lessens learned, would like to know your opinions.
