Electrical System
Electrical System
Overload
The vehicle has fuses and
circuit breakers 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 and circuit breakers
protect power devices in the
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.
