12 Volt Electrical Switches

[Doug]

I am trying to better understand my 32+2 CB Battery switches.
Near the door there are 3 Battery switches in a vertical row. The top one is labeled "House", the center one is labeled "Bow Thruster" and the bottom one is labeled "Engine". By disconnecting each of my 5 batteries I think I have determined which one does what.

I tried to attached is a crude drawing of what I think I have, but it was to big for this site. It looks like I have 2 banks of 2 batteries each. Each switch is capable of switching to either bank. Is this the normal battery switch setup for a 32+2? It looks to me like putting any of these 3 switches in the "Both/All" position will tie all the 4 batteries together. Is this correct? Please let me know if your system is different. My fifth battery is for starting the generator.

Thanks,
Doug

3 switches! Now that is different. In the original configuragtion I had 2X3 position switches controling 3 banks of batterys. Any bank could be used independently or combinded to serve any purpose, except start the genny.

Switch 1 linked banks #1 or #2. Switch 2 linked bank #3 or #3 to what was on on switch 1.

I now have 5 batterys in that system. 2X2 in paralel for banks #1 & #2 & a single for #3.

3 of those 5 have completed 9 years of service. The other 2 are 6 years old. Still load testing strong.
