We put a ProMariner ProSport 20 plus 3 bank battery charger in the Beneteau in June of 2018. It worked well to keep the batteries at full charge. The only draw on the battery system is an intermittant 5a draw from the refrigerator. Back in Sept., when I was installing the new AC shore power ckt. breaker panel, I started noticing that the 30a pedestal breaker (GFI) would trip a few minutes after turning on the battery charger. I figured I had an issue with the way I wired the new panel, but that could not be...I know wiring of AC/DC power systems. Then the charger stopped turning on. The only light on was the blue AC light and no other lights would illuminate and no system check OK. It had stopped working. My AC wiring was not the problem.
I called the 800 number in their owners manual and briefly talked to the rep. He said to try removing the battery selector cap and turn back on to see if it cycles on with the Gel battery selected vs. the lead acid that I had selected and was set like that from the factory. Upon removing the selector cap and turning the charger back on, the charger cycled on and started charging in the Gel battery profile. The company fix was to cut or grind away part of the selector cap. Since they were on the phone, no visual instructions on how to modify the cap and the Battery Charger is still under warranty, I asked for them to send me the factory fixed cap, which I recieved the next day from New Hampshire. Their new battery selector cap did the trick and the charger works great again. Here are some pictures and explainations of what I see.
The charger is in Gel charge profile with the original black cap installed, lead acid cap/screw top of pic. Gel profile, green light at bottom.
The difference in the caps...The original is on the right. The new, factory fix, on left.
The charger is working again and was a very simple fix. Notice the red light where the battery type is, was green above. Putting this info. out there as I know there are other users here of these chargers. At least I did not have to take it out of the boat and send it away for warranty repair.
