Hello. All my batteries froze in my cart this winter and I had to replace them. When I put the new batteries in I put all the batteries facing away from me. I looked at a friends cart and all the batteries faced me. Did I do something to the cart, or any of its parts by hooking it up backwards at first. The backup beeper doesnt work or anything. Does not move forwards or reverse. All connections are clean and tight. It is a 1999 ezgo. It has the box with the run/tow toggle switch. I thought maybe the batteries were dead but the dealer advised me that the batteries come 80% charged. I tried hooking up the charger and it didnt even kick in to start charging. The outlet works because i tried plugging something else in. Is it some sort of fuse that has blown or what. Please help
