First off welcome to BGW, The issues you are having could be any number of things, more input will be required. For starters, on the frame toward the rear of the cart is a plate that hold the mystery information required to know your year and model of your cart. Its on the cross member, right next to the rear tire on the drivers side (usually ) I have attached a pic to show where it should be. Also link with the info that should help you with the identification.
We'll be looking forward to more input and pics, Many other knowledgeable members of BGW will chime, and are willing to help. Good Luck
