3 Bank charger issues

[Big Kahunaz]

Red and green light are lit on my battery 2 and only red light is lit on my battery 3....both are my trolling batteries. Red light says check connection. I've checked all my inline fuses....and terminal connections...everything looks good. Anyone have any suggestions on what could be the issue? I'm not getting any power to my trolling motor either.

Just a guess.....

Could you have a bad cell in battery # 3.

Maybe if you disconect the batteries and try connecting a charger to just 1 battery at a time. The charger may tell you that one battery is bad.

Also......you might still have a "bad" connection on one of the batteries. Take the wires off and clean each connection with sand paper or wire brush.

Good luck finding your problem. An auto parts store could maybe test your batteries. You can buy a simple "eye dropper" looking tester to check the acid in each cell to see if it is charged up.....they only cost a couple of $$$.

I could....not sure why all of a sudden ....batteries are less than 1 year and maintained. I'm gonna test it tomorrow. All my terminals are shiny clean.

I have seen this several times with the minn kota chargers. If the batterys drop below 12 volts the minn kota charger cant bring them back up. Try putting a regular trickle charger on them for a little while then plug the minn kota charger back in and see if that works.

That is correct with just about any of the new chargers, if one of those batteries is dead it won't charge it. It has to have a little charge already in it for them to charge.

bad cells in batteries go out like a switch in my experience dude

Ok fellas...got all the kinks worked out...batteries were drained and so i guess as stated earlier the 3 bank wouldn't charge them.....tested them out all is good to go after individually charging. think i left my trolling motor just barely on and it ran my batter down.
