I have the Pro Pack IV charger that came installed on my 07 Puma, and I have been having some issues with it charging the batteries. Sometimes the lights for two of the four banks dont light up at all, and sometimes the same two banks will flash red and green. I was convinced it was a battery issue, but started testing the batteries with a digital meter, and found that there wasnt any charge going to those two banks. I removed the pro pack, and have been charging each battery with a single 12V charger, moving it from battery to battery manually. When I removed the pro pack, I found that one of the fuses on the positive lead was broken, and I am looking to test the charger while it is not installed on the boat. Has anyone tried to test the charger, and if so, did you run into any issues when you did with no load being on the charger? Thanks in advance.Allen
