3 marine batteries on a dual charger

An older type of breaker or you have a total of to many amps being drawn. try a differnt plug or the charger is the problem.

first of all do you have 3 or 4 batteries your cranking battery is not to be wired into this 36 volt if you have 4 batteries you have 3 for trolling motor and 1 cranking battery look on your charger see if the banks or numbered 1 2 3 4 .... you got to find what battery is # 1 depends on how they hooked in series if you hook charger on wrong battery most the time a red light comes on telling you wrong battery move wires till green lights come on all batteries.# 4 goes to cranking battery if you only have 3 batteries you don't have 36 volts you have 24 volts and a cranking battery if so # 3 goes to cranking battery

no.. you have the wrong wire going to wrong battery swap them around before you burn charger up or battery

It sounds to me like you have an Ad-A-Battery system or something similar. Your dual battery charger has two sets of output leads. Those leads should be connected DIRECTLY as one set of leads to battery #1 and one set of leads to battery #2. Your 1-2-both switch should be OFF when you are charging. You will, I suspect, be supplying current to your motor and other boat circuits by having the switch on and running your charger through that switch. Adding two more batteries could be accomplished by buying a four battery charger (four sets of output leads) or buying a second dual battery charger. When you only want one AC plug-in you connect both charger AC inputs to a small junction box that is fed current by the AC plug-in. That will be nice and simple and safe. Of course, you need to check wire size to make sure you have proper size for the length of your wire runs.

no problem put neg on neg pos on pos on each battery but make sure you have charger on the battery it goes too look on your charger see if the banks are numbered 1 2 3 4 put 1 on # 1 and so forth # 4 goes on your cranking battery if you get a red light on charger then you have wrong wire on wrong battery and yes it will make you pull your hair out till you get it right . . .lol

if you are trying to wire the batteries for teh 24 volt motor then you need to connect the positive of one battery to the negative of the other battery. then connect the trolling motor to the remaining two terminal of the batteries.

if you are trying to connect the charger to the batteries then each battery should have its own set of wire coming from the charger.these wires should be connected to the batteries in a set not crossed between batteries.
