just bought an old Legend cart. Guy said it will need new batteries. It did drive forwards and back and up on a trailer. Batteries look as old as me. Bought 2 new deep cycles today and took out two old ones. really didn't make a lot of difference. Wondering if I have to replace all 6 before it will run right or maybe have an additional issure with the motor or something. Have no idea of the model and can't find a vin plate to find out the year. Any thoughts if weak drive is just in need all 6 new batteries or what. Any help would be great
