is it doing anything? 1st make certain the battery is good and ends are very clean and put on tight, open the small black box ( well not that small ) has just a screw in the middle......there is a fuse block in there chances are only one fuse in there its a 10 amp red fuse make sure its good, if not replace it cart might just start turning over, if fuse is good jack rear wheels off ground or put cart in maintence mode, ( by the way make sure its not in maintence mode now)........put cart in nueltral if it turns over put knob in right place........if its none of that get a peice of 6 gage cable....about 8 inches is more than enough, jump the large post on solenoid and try and start cart if it turns over replace soleniod.............start with these things and i,m sure some other members should have some ideas to add but this is a start..............................
