On board charger problem

[Ljones]

Minn Kota 315 d 3 bank charger .. #1 and 3 banks go green light saying the batteries are charged the # 2 bank stays yellow then goes to yellow with a red light .. I can then swap the charger leads with the # 1 bank and battery with the # 2 bank and battery within a few minutes the #2 and # 3 will go geen light and the #1 bank stays yellow then finally goes red and yellow this sounds confusion but the problem is changeing batteries when I swap the leads can any one make any sense of this and tell me what's going on ? It sound charger related but it's doing the same thing with 2 different chargers ,.. Batteries are about 3 years old

Is the same battery causing the charger to go yellow and red. If so I would say you've got a bad battery.

Different battery

Charger bank is bad. Call minkota and check warranty even though it might be out.

I'd disagree that the charger is bad, because the problem is moving. In scenario one, C1/B1=G...C2/B2=R...C3/B3=G and in scenario two, C1/B2=R...C2/B1=G...C3/B3=G. In both cases, only B2 is red, which means B2 is bad

Your right Vic n # 2 battery was bad
