2021 MG MG3

Fuse and Relays

Fuses are simple circuit breakers which protect the car’s electrical equipment by preventing the electrical circuits from being overloaded. A blown fuse may be indicated when the item of electrical equipment it protect stops working.

The mounting location and rating of each fuse is shown on the label printed on the fuse box cover.

If a fuse is suspected faulty, you may remove it from the fuse box and observe if the metal wire in the fuse is blown.

It is recommended to have spare fuses in the vehicle, which can be obtained from a local MG Authorised Repairer.

Comparison Before and After the Fuse is Blown

 

IMPORTANT
• NEVER attempt to repair a blown fuse. ALWAYS replace a fuse with one of the same rating.
• If a replaced fuse fails immediately, please contact an MG Authorised Repairer as soon as possible.

Fuse Box

The vehicle is equipped with 2 fuse boxes:
• Engine compartment fuse box (on the left of the engine compartment).
