For electrical problems, it is best to see a Harley-Davidson dealer who has the necessary parts and equipment to perform electrical services.
Accessing Fuse Blocks and Relays: All VRSC Models Except VRSCR
VRSC models (except VRSCR) have a front fuse block and rear fuse block.
  1. Make sure the ignition is turned OFF.
  2. See Figure 1 and Figure 3. To access front fuse block, remove the fastener from the front right side cover and carefully lift the side cover off the mounting tabs. The front fuse block is mounted on the top right side of the battery box.
  3. See Figure 2 and Figure 4. To access rear fuse block, open the seat. The rear fuse block is located on frame crossmember behind fuel filler cap.

Fuse Replacement: All VRSC Models Except VRSCR
Fuses do not reset. A blown fuse must be replaced.
1. For rear fuse block, slide the fuse block off the mount.
2. Remove the suspect fuse and inspect the element.
NOTICE
Be sure both vehicles have the same battery voltage when jump starting. Connecting vehicles with different system voltages can result in vehicle damage. (00220c)
3. Replace the fuse if the element is burned or broken.
NOTE
Use only automotive type ATO fuses as replacements.
4. For rear fuse block, slide the fuse block onto the mount. Close the seat.
5. For front fuse block, replace side cover on the mounting tabs. Line up the hole on the cover with the threaded hole in the frame tab and install the fastener. Tighten the fastener to 11–17 N·m (97.2–150 in-lbs).

3. Slide each fuse block assembly back into the fuse block cover. Push the fuse block assembly into the cover until the cover release tab snaps into place.
4. Replace the airbox cover. Turn the bailhead fastener 1/4 turn clockwise to secure the cover.
WARNING
Never route throttle cable over the battery. Fire due to short circuit could occur and cause death or serious injury. Throttle cables must be routed alongside battery, between hold down strap and coolant overflow bottle. (00224a)
5. Close seat.
Replacing The Maxi-Fuse: All VRSC Models
All VRSC models have a main fuse to protect the motorcycle wiring. This 40-amp maxi-fuse provides main battery power to the motorcycle. It is located in a rubber-coated fuse holder behind the motorcycle's right side cover.
1. See Figure 7. Remove the fastener, carefully lift the side cover off the mounting tabs and set it aside.
2. Grasp the fuse holder in one hand, the plastic body of the maxi-fuse in the other, and pull the maxi-fuse straight out of the fuse holder.
3. Insert the prongs of the new maxi-fuse in the fuse holder slots. Push the maxi-fuse firmly down into the fuse holder.
4. Replace the side cover on the mounting tabs, line up the hole in the cover with the threaded hole in the frame tab, and install the fastener. Tighten the fastener to 11–17 N·m (97.2–150 in-lbs).
