I have the ProPak 3 charger on my boat and am seeing today when I plugged it in after fishing that only one light went red, the other two did not light up at all. This is both at the gauge and on the charger itself. The connections look fine at each of the batteries, so is the next thing to be is cut the shink tubing off the fuses and see that they are not popped? Using a volt meter I could see one battery was at 13.6v and the other two were at 12.6v so it doesnt look like it is still charging but not showing that it is.If it turns out the charger is dead, is installing a 4 bank in its place farly straight forward? Or am I best to get another 3 bank?
