1. Control board is bad. If you cannot find the original, a later model one piece board will work.
2. The two 1/4" push on connectors on the terminal board, used to have a varistor between them.
Used for surge protection, not needed for operation.
3. If the battery pack voltage is increasing when the charger is hooked up and running, amps are flowing, so the meter movement is bad.
Chances are you won't find an exact replacement, but any 0-30A DC ammeter will work. Just find a surface mount one whose backside will fit through the hole and drill some holes for the mounting screws.
Also, if you ever blow the press-fit diodes, just drill a couple holes in the heat sink and use 1N1184 stud-mount diodes.
