Replacing the Main Fuse
All Sportster models have a main fuse to protect the motorcycle wiring. This 30 amp main fuse provides main battery power to the motorcycle. It is located in a rubber-coated fuse holder behind the motorcycle's left side cover.
To remove, grasp the fuse holder in one hand and the plastic body of the main fuse in the other. Pull the main fuse straight out of the fuse holder.
Insert the prongs of the new main fuse in the fuse holder slots. Push the main fuse firmly down into the fuse holder.
