Electrical System

Overload

921LL
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
194LL
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
H9
normal or the problem is fixed. This
H11
greatly reduces the chance of circuit
overload and fire caused by
194LL
electrical problems.
Fuses and circuit breakers protect
3057
power devices in the vehicle.
Replace a bad fuse with a new one
of the identical size and rating.
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.
