Hi: I have another earlier posting for the wrong item (Sierra 446). Just found that my cart may be and Indutrial 835 made in the 80' or 90'. I really need a wiring diagram to determine whether or not the wires are correctly placed since installation of new batteries give me severe sparking when trying to connect the last positice cable. Still trying to find the diagram through EZ GO and several sales dealers, but am not sucessful. If you could help certainly would be appreciated. THANKS.
