You can also consult the manual to confirm the fuse. Once you have identified the fuse, confirm it by connecting it to the multimeter.

Connect one end of the multimeter with fuse one end and the next wire end to the other end. If you see the voltage passing, the fuse is okay. Otherwise, it needs replacement.

Cut the faulty wire and then repair it with a new wire. If you see the wire is damaged badly, it is better to replace it.
