Checking and Replacing Fuses
A fuse is an element for protecting the electrical system. A fuse will trip (i.e. it will blow) in the event of a failure or improper interventions in the electrical system.
If an electrical device is not working, check whether the respective fuse is blown. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Check those fuses first that protect the failed component, but check all the fuses before deciding that a blown fuse is not the cause. Replace any blown fuses with another with the same amperage (same color) and check the component’s operation.
Notice
- Never replace a broken fuse with anything other than a new fuse. Always use a fuse of the same color.
- Fit approved replacement fuses of the same rating and type, or fuses of a matching specification. Using an incorrect fuse may result in damage to the vehicle’s electrical system and can result in a fire.
- Always switch off the ignition system and the affected electrical circuit before replacing a fuse. Failure to do so could cause damage to the vehicle.
- If the replacement fuse blows after fitment, the system should be checked by a retailer/authorised repairer. Further damage could be caused to the vehicle if ignored.
Location
- Engine compartment fuse box.
- Passenger compartment fuse box.
- Tow hitch fuse box.
- 6-way satellite ATO fuse box (Armoured)
