Electrical System
Electrical System Overload
The vehicle has fuses to protect against an
electrical system overload.
When the current electrical load is too
heavy, the circuit breaker opens and closes,
protecting the circuit until the current load
returns to normal or the problem is fixed.
This greatly reduces the chance of circuit
overload and fire caused by electrical
problems.
Fuses protect the wires that provide the
power to the devices in your vehicle.
If there is a problem on the road and a fuse
needs to be replaced, the same amperage
fuse can be borrowed. Choose some feature
of the vehicle that is not needed to use and
replace it as soon as possible. To check a fuse, look at the band inside the
fuse. If the band is broken or melted,
replace the fuse. Be sure to replace a bad
fuse with a fuse of the identical size and
rating.
