Golf Car Catalog offers a great selection of starter generator belts, for a wide variety of golf cart brands and models, including EZGO, Club Car, Yamaha, Columbia Par Car, Harley-Davidson and others.
The golf cart starter/generator belt is similar to the 'V' belts on automobile alternators. They are thinner, shorter and should not be loose or floppy. It should not have cracks or delamination either. This belt connects the starter/generator to the drive clutch on the engine. It starts the engine and then, at higher RPM, begins to recharge the battery, hence the name starter/generator.
