Fuses – colours and ratings
Automotive fuse types
Identify the fuse construction before selecting a replacement. A matching colour in a different fuse family does not establish the same design.
Colour coding and ampere ratings
Use colour and ampere rating only with the table for that fuse type. This section does not reproduce fuse-box positions or consumer assignments.
Selecting the correct fuse
Use the exact vehicle manual, the position in the correct fuse box, the fuse type and the specified ampere rating.
Safe replacement
Switch off the relevant consumer and ignition as instructed. Use only the same type and rating; repeated failure requires diagnosis.
Fuse colour coding
This table applies to the common ATO/ATC family of blade fuses. It is not universal for every fuse construction. Colour alone does not confirm the correct construction type, dimensions or position in the vehicle. Always check the rating marked on the fuse and the specification for the exact vehicle.
