Hello, I only am getting power to my servos from my left battery input. If I unplug my left battery, or turn it off with the switch, but have the right on, I get no power to the servos. I remember possibly plugging in my battery with reverse polarity once in error, and I also read that will ruin the regulator. I did not panic initially, since I'm running A123 at 6.6V and don't need the regulator, however when testing I realized I'm not getting any power at all from that battery to my servos. Does that make sense, and can I send to Powerbox USA for repair? Will the repair keep my programming intact, or would I have to re-program?
