Most of the power supply circuits of the vehicle's electrical equipment are protected by fuses

The battery charging circuit, engine starting circuits, and generator are not protected by fuses.

Replacing Fuses and Relays

Before replacing a blown fuse, find out the reason for its combustion and eliminate it.

Always have a set of spare fuses with you.

Do not replace fuses with jumpers and fuses rated for a different amperage, or with a homemade jumper.

This can cause damage to electrical appliances and even a fire.
