I used to run a 12/24 volt trolling motor using my 3 bank charger. (the charger came with my Ranger boat, the charger is made by "Charging Systems International".) I have now switched to a 24 volt trolling motor. So, now that I've switched to 24 volt, do I keep a pos and neg charging cable on both TM batteries, or, put connect to the positive terminal on one, neg on the other, and leave my third bank free?
