FUSE
Fuses are the most common form of circuit protection used in
vehicle wiring.
A fuse is a thin piece of wire or strip of metal encased in a
glass or plastic housing.
It is wired in series with the circuit it protects.
When there is an overload of current in a circuit, such as a
short of a ground, the wire or metal strip is designed to burn
out and interrupt the flow of current.
This prevents a surge of high current from reaching and
damaging other components in the circuit.
Determine the cause of the overloaded before replacing the
fuse.
Never replace a blown fuse with a fuse of a different amperage
specification.
Doing so can result in an electrical fire or other serious circuit
damage.
A blown fuse is easily identified.

FUSIBLE LINK
The fusible link is primarily used to protect circuits where high
amounts of current flow and where is would not be practical to
use a fuse.
For example, the starter circuit.
When a current overload occurs, the fusible link melts open
and interrupts the flow of current so as to prevent the rest of
the wiring harness from burning.
Determine the cause of the overload before replacing the
fusible link.
The replacement fusible link must have the same amperage
specification as the original fusible link.
Never replace a blown fusible link with fusible link of a different
amperage specification.
Doing so can result in an electrical fire or other serious circuit
damage.
A blown fusible link is easily identified.
