3 bank charger wiring diagram

Wondering if any one knows where I can look at a wiring diagram for hooking up a 3 bank charger to my cranking battery & to my 24volt deep cycles?

The two 12 volt deep cycles are wired together but I cant leave the charging wires connected to the batteries unless I remove the wire connecting the two batteries, something is wired wrong. Thank you.

All you need to do is hook up a + and - from each bank to each battery. No matter if you have a 12v,24v or 36v it doesnt change how you hook up the charger. Make sure you have your 24v system correct...Hope this helps.

Thanks skeeter.

I know the charging system should be connected to the batteries at all times, but, like you say- my deep cycles must be hooked up wrong. As it sits now, I cant have the charging wires connected while the batteries are wired together, I get red blinking lights on 2 of the charger banks. I've looked at a wiring diagram for connecting two 12v batteries & mine are connected the way it shows, doesnt make sense. I have a lead going to a negative terminal on 1 battery, a lead going to the positive on the other battery & a wire connecting the two going from pos to neg. But, I cant hook the charging wires up without removing that connecting wire.

Huh is there anything that says on the charger that it cant be hooked up when the batteries are hooked up together? I have never seen it but just a thought.

Like on my 24v system I got the troller wires + on one batt and - on the other and then the jumper between the 2. Then I run 2- 12v for my starting/electronics hooked up parallel. I have a 4 bank minnkota with each bank going to each batt.

No there isnt- It's wired exactly how its shown here except I have a 3 bank & have a cranking battery wired to it also, dont have a switch.

Problem is I bought new batteries 2 yrs ago & had a friend help install while I replaced the trolling motor at the same time, didnt see exactly what he did but it isnt right.

Thanks for the input, gunna go through it tonight. I just may tell the wife it's time for a new 621 & sell this 521 comanche, want a boat more suited for big water.
