three bank charger

[countrybraves]

if a three bank charger is only charging two batteries is there a way to fix the unit or do I have to buy a new one? the unit looks sealed any help.

No need to use the 3rd lead (until you add a batt)

If you are going to stick around here, you will need to add more stuff which will require a 3rd batt

how about a starting battery, two trolling batteries

I think the original question meant that only 2 of the 3 batteries are charging and it needs "fixing". If it is sealed and out of warranty you are up fish creek. Give us the brand and model, perhaps someone who has had the same problem can help.
