Reply With QuoteEasiest way to tell is to switch two of the batteries.
If 1 & 2 are green with 3 red - switch 1 with 3 on the charger leads and see if the red follows the battery (=battery bad) or if 3 stays red = charger bad.

MK 330D charger question
So, after 4 days on the charger, two banks have turned solid green (long term maintenance), but bank #2 is still flashing green (fully charged maintenance). Why is it not switching to solid? Charger issue or battery issue?

The switchover from flashing green to solid is a time function which starts when the flashing green starts. Probably what is happening is that occasionally the charger is switching out of maintenance to charge, then back to maintenance.
Could be a battery or the charger. More common is that there is a small drain on the battery causing the whole thing to recycle. If this is a TM battery, try unplugging the TM. If it's the cranking battery, it might be tougher to find if there is something like a compartment light stuck or maybe just the accumulated current of a radio and the the outboard.
All it takes is a short power demand that exceeds an amp.
Check electrolyte levels in the battery.
Do the cable swap like Clint suggested above.
Once you get through those things, it will be narrowed down.
