Fuse Replacement
  1. Turn the ignition to the OFF position.
  2. See Figure 1. The left side cover (1) provides access to the maxi-fuse holder (5), battery (6) and fuse/relay block (4). No tools are required to remove or reinstall the side cover.
  3. The left side cover is secured to the motorcycle by two upper slots that fit into upper clips (2) and a bottom slot (3) that fits into a mounting tab on the battery tray.
NOTE
The left side cover does not need to be completely removed from the vehicle to access the battery or fuses.
1. Place a shop cloth or other clean, dry cloth over rear brake master cylinder reservoir and left passenger foot peg (if equipped). This will protect left side cover from damage.
2. Grasp left side cover at upper corners and gently pull away from plastic mounting clips on frame.
3. While rotating top of cover out away from motorcycle, slide cover down slightly so mounting slot slides down from mounting tab on battery tray. Side cover will now rest on top of rear brake master cylinder reservoir and left passenger footpeg (if equipped) with slot hanging off bottom of mounting tab.
4. Locate and replace any fuse in the fuse/relay block with a burned or broken element. See Figure 2 , Figure 3 , and Table 1 to identify which fuse protects an inoperative circuit.
NOTE
Automotive type ATO fuses are used for installation and replacement.
NOTICE
Always use replacement fuses that are of the correct type and amperage rating. Use of incorrect fuses can result in damage to electrical systems. (00222a)
5. Place bottom of side cover with grommet in frame and press top of side cover into clips until snug.

Replacing the Maxi-Fuse
All Sportster models have a main fuse to protect the motorcycle wiring. This 30 amp maxi-fuse provides main battery power to the motorcycle. It is located in a rubber-coated fuse holder behind the motorcycle's left side cover.
  1. Grasp the fuse holder in one hand and the plastic body of the maxi-fuse in the other. Pull the maxi-fuse straight out of the fuse holder.
  2. Insert the prongs of the new maxi-fuse in the fuse holder slots. Push the maxi-fuse firmly down into the fuse holder.
  3. Grasp top corners of side cover. While rotating top of cover up towards motorcycle, gently pull cover up so that mounting slot slides up mounting tab.
  4. Line up top slots of side cover with mounting clips on motorcycle frame, aligning with front clip first. Press top of side cover into clips until snug.
