im swapping my trolling motor over from 12v to 24v. i know how to wire the batteries for the trolling motor (in series). My question is about the charger, i have a 3 bank 15 amp per bank charger, one battery in back for the primary motor and electronics (im all set with), and 2 up front for the tm,..do i just hook it up one lead (or bank) per battery up front? or do i have to arrange them in a different manner now that the 2 batteries up front are going to be in series? I bought this charger 15 years ago and cant find the manual,..i looked on line for the manual, found it, downloaded it on my computer,.., but now i cant find the proper way to open the file,...lol (im no computer guy by any means)  I figured that there has to be plenty of you here that have this system on your rig

Thanks for any help provided

You hook up the charger one set of leads(1 pos and 1 neg) for each battery as though they were the only battery. Charger should have three sets of leads, one set for each battery. Red lead is positive, black lead is negative for each battery. The charger has three separate circuits, each 12 volts. 

Each bank goes to a battery, doesn't matter if its rigged 12-24-36. 

Thanks guys,... thats what i figured,.. but wanted to be sure before i just went and hooked it up
