Buick Enclave: High Voltage Devices and Wiring. Electrical System Overload. Fuses and Circuit Breakers
High voltage components are identified by labels. Do not remove, open, take apart,
or modify these components. High voltage cable or wiring has orange covering. Do not probe, tamper with,
cut, or modify high voltage cable or wiring. 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. 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. Headlamp Wiring An electrical overload may cause the lamps to go on and off, or in some cases
to remain off. Have the headlamp wiring checked right away if the lamps go on and
off or remain off. Windshield Wipers If the wiper motor overheats due to heavy snow or ice, the windshield wipers
will stop until the motor cools and will then restart. Although the circuit is protected from electrical overload, overload due to heavy
snow or ice may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield
wipers. If the overload is caused by an electrical problem and not snow or ice, be sure
to get it fixed. The wiring circuits in your vehicle are protected from short circuits by a combination
of fuses, circuit breakers and fusible thermal links. This greatly reduces the chance of fires caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted,
replace the fuse. Be sure you replace a bad fuse with a new one of the identical
size and rating. Fuses of the same amperage can be temporarily borrowed from another fuse location,
if a fuse goes out. Replace the fuse as soon as you can.High Voltage Devices and Wiring
WARNING
Exposure to high voltage can cause shock, burns, and even death. The high voltage
components in the vehicle can only be serviced by technicians with special training.Electrical System Overload
