does the charger check out? use a volt ohm meter to check the chargers output. when you charge all four batteries us the meter to check the batteries charge. this should give you an idea where the problem is.

It sounds like you need a new charger I'm afraid. If you want to double check though, take the housing apart (4x security torx screws in the underside corners) and check the little glass fuse on the pcb. If either main fuse or glass one is blown you have a problem with the board and it's not worth repairing. If both fuses are ok I would suggest you might have a dry solder or broken leg on one of the pcb components. You could possibly resolder it if you can find it and it has enough contact left.
