I have had my boat drydocked from most recent storm. House batteries drained and were dead, although I was able to start engine and use thrusts when dropped into water. Upon arriving at home pier, I connected ac power cords to boat--lights came on AC1 and AC2. Lights were on at panel inside my R-31 boat 2012. Lower bank had lights and meter read power; however upper bank shows no lights and meter reads no power. I make sure all power cords are working and they are. I make sure pro mariner is "on" position but the green lights come on for a flash and I turn it into "on" position but then it goes out with no lights at all. I've let boat sit with charge and power for past 4-5 hours but nothing happens. I am unable to use any of my electronics. Does this mean I have a defective pro mariner switch or is it that my boat had been drained so much power, that this switch will not come on until everything is fully charged and then pro-mariner switch will light up green. Remember, the power bank "2" is operational and shows "power on needle" but the ones (banks) above "2" are completely dead with no power showing on needle. Can you tell me next step?
