Overload
The vehicle has fuses and circuitbreakers to protect against anelectrical system overload.
When the current electrical load istoo heavy, the circuit breaker opensand closes, protecting the circuituntil the current load returns tonormal or the problem is fixed. Thisgreatly reduces the chance of circuitoverload and fire caused byelectrical problems.
Fuses and circuit breakers protectpower devices in the vehicle.
Replace a bad fuse with a new oneof the identical size and rating.
If there is a problem on the road andafuseneedstobereplaced,thesame amperage fuse can beborrowed. Choose some feature ofthe vehicle that is not needed to useand replace it as soon as possible.
