I disconected my batteries over the winter. I had my marina install them a few weeks ago. My accessory battery is no longer charging and drains within a few minutes. I do not know the original set up to see if they are connected properly. Can someone explain what to look for to see if they are correctly hooked up, or is there a manual out there that will show me a diagram? Anyone tried surfing without tunes? Let me tell you, it blows!!!!
