Checking and replacing a fuse

Spotting a blown fuse and replacing it with one of the same rating — if it blows again, a mechanic.

This guidance is general — not checked for any one model. Your bike's exact figures and procedures are in its owner's manual or at an authorised service centre.

Basic owner maintenanceDifficulty: Easy10 minutes

When to do it

  • When several electrics stop at once
  • When nothing lights with the key on

What you need

  • A new fuse of the same amp rating
  • A fuse puller, if supplied

Step by step

  1. 1

    Keep the key off. Find the fuse box in the manual (often near the battery).

  2. 2

    Use the lid or the manual to see which fuse does what.

  3. 3

    Pull the fuse and hold it to the light — a broken wire inside or a scorch mark means it has blown.

  4. 4

    Fit a new fuse of the same amp rating (the same number and usually the same colour).

  5. 5

    Turn the key on and see whether it works.

Warnings

  • Never fit a bigger fuse, wire or foil — the wiring can overheat and catch fire.

Stop and see a mechanic if

  • The new fuse blows too — there is a short circuit somewhere
  • A burning smell or melted wiring
