Power Converter stopped charging batteries.In the end, I went ahead and upgraded to the Progressive Dynamics model PD4635V, got a new but open box from Amazon for $120, install was very easy and straightforward. Thanks for the advice everyone!Re: Help! Power Converter stopped charging batteries.Thanks for the suggestion, I will check the back of the unit. I have two Duracell 6v golf cart batteries from Sam's Club wired in series, and the old converter worked fine for my needs. How much better will a new converter be? I also plan on adding either one or two 24v solar panels with an MPPT charge controller, as well as a pure sine inverter.. How much will I benefit from a new unit? I see a deal on a Progressive Dynamics PD4635V.Help! Power Converter stopped charging batteries.So, I just did something very stupid.. While reconnecting my RV batteries, I accidentally mixed up the positive and negative terminals and left it that way for about 5 minutes until I finally noticed and reconnected them correctly. Ever since then, whenever I'm plugged into shore power (or generator) all the outlets will work fine, and the DC powered items (lights, fan, etc) all work correctly, however the batteries no longer are charging. All the fuses and breakers seem good, and I don't see any damaged wires or anything.. and clues where I should start next? Side note, the CD/Radio player has stopped working, and that fuse also looks fine, so I'm suspecting it was damaged with the mixup, or its not getting power for some reason. I can diagnose that another time, but the battery chargers are most important! I will post a picture of the unit and diagram - I believe the power converter is the 2nd breaker as labeled.
