Does a scooter have just one fuse ? | Scooter Shack I have a Yamaha YN50 and it´s got one fuse. The fuse is connected to the electrics surrounding the battery. I had a period where I was literally blowing fuses every day. I worked out that it was my starter motor that was knackered and NEARLY mad every time I tried to start it with the electrical starter the fuse was blowing.
