What is a Fuse and How Does It Work?
If there’s too much current going through the fuse, it will “blow.” When this happens, the electrical circuit breaks, which protects the electrics from further damage.
There are two main types of fuses for motorcycles:
- Blade-type fuse
- Glass fuse






What is a blade type fuse?
- A plastic case – acts as a body for the copper thread, and the metal connector
- A thin copper thread – also known as the “conductor,” the job of the copper thread is to break the circuit when the electrical current becomes too strong
- A pair of metal connector prongs – connects to the connection port inside the fuse box
The fuses sit inside the motorcycle’s fuse box, which in turn sits underneath your seat, right next to the battery.
Now that you know where the fuses are, you’re ready to replace the broken one.
But first – how can you tell what Ampere rating the replacement fuse needs?
Blade Type Fuse Color Coding



- A replacement fuse with a lower Ampere rating will have to be replaced again
- A replacement fuse with a higher Ampere rating might cause an electrical fire
Have you looked at your fuses and noticed that some have a different color than others?
That’s no coincidence – this color coding is there to tell you the Ampere rating of the fuse in question.
This means that you can determine the correct Ampere rating for the fuse just by its color.
Fuse Color Coding Chart:
Color: | Ampere: |
Violet | 3 Ampere |
Pink | 4 Ampere |
Tan/Beige | 5 Ampere |
Brown | 7,5 Ampere |
Red | 10 Ampere |
Blue | 15 Ampere |
Yellow | 20 Ampere |
Clear (transparent) | 25 Ampere |
Green | 30 Ampere |
Are car and motorcycle fuses the same?
How much does a fuse cost?
Fuses themselves aren’t expensive – using the wrong one can be though.
