Electrical fuses
CAUTION
Risk of accident and injury
If you manipulate, bridge or replace a faulty fuse with a fuse of a higher amperage, the electric cables
could be overloaded. This may result in a fire.
►
Always replace faulty fuses with specified new fuses of the correct amperage.
The individual electrical circuits are protected by safety fuses or automatic circuit-breakers.
■
Blown fuses or defective automatic circuit-breakers must be replaced by equivalent fuses with the
fuse ratings recommended in the fuse allocation chart. Fuses with the same fuse rating are the
same colour. Further information is available from the engine supplier or its service support point.
■
The fuse allocation chart is vehicle-specific and is provided by the vehicle manufacturer.
"Fuses and relays" (p. 66)
■
If the newly inserted fuse also blows, have the cause traced and rectified at a qualified specialist
workshop.
■
If a circuit fails, switch off the consumer equipment and switch the ignition lock to position 0.
■
Checking and replacing a safety fuse
1.
Pull the fuse out of the module using the pliers and carry out a visual inspection.
2.
If the fuse wire has melted, replace the blown fuse with a spare fuse.
3.
Switch on consumers and check that they function correctly.
If the safety fuse burns out again, have the electrical system checked at a qualified specialist work-
shop.
