Oh, I have that Pergo switch also. It guarantees the power is off, AND it also allows you to use your trolling motor battery(s) and run them down, but still leave your starting battery fully charged so you can crank you big motor when it is time to head back to the dock. The on-board charger is mainly to SIMPLIFY charging and then assure your batteries are "topped-off" if you don't use your boat.
To test your on-board charger just hook up a voltage tester to the positive and negative leads, plug it in. If the voltage is about 13.5-14.5 v, then it shows the charger is charging. If not, then its not working. Takes only a few seconds to test.
