Are all the batteries filled to the proper level ? Had a guy the other day bought some and one of the batteries did not have anything in it.
I have a Dual Pro 4 bank charger. I just bought 3 brand new group 31 batteries. I used them once, charged them and the were ok. The second time I used them, I tried to recharge them. My charger has 5 lights, showing stages of charge. After a few hours, it was still on one red light, indicating minimal charge. Then, the charger went to 2 blinking red lights on all 3 banks. This, according to my research, indicated the charger overheated and this is a safety cut off. I unplugged it, let it cool, and same result. The cranking battery charged ok. No way all three batteries are bad. Thoughts, and thanks.

I would try the others on your manual charger then...if they all charge up then your batteries are fine. in that case it would have to be either a wireing problem or connections....or something is wrong with your on board charger.

Abe, how low were your batteries. I know on most onboard chargers if they get two low they won’t charge. Put that charger on for 30 minutes then shift back to onboard and see what happens. Also do as G suggested and double check wiring set up.
