If anything happens
General information
The first measure to take when carrying out fault tracing of
the electrical system is to check the fuses. Both fuses and
circuit breakers are included in the bus’s electrical system.
A tripped circuit breaker can be seen by the protruding red
reset button. Remove the fuse from the holder and reset it by
inserting a pen or small screwdriver through the ”window”
on the side of the fuse.
If the same fuse blows repeatedly, the bus must be driven to
a garage for service to the electrical system.
Even an apparently intact fuse may require testing. If a fuse
is suspected of being defective, remove it from its location
and press it into the socket on the far left of the row fuses on
the main distribution box (position 24). There is a green
LED above this position that will go on if the fuse is intact.
The battery master switch must be on while performing this
test.
Starting problems
Make sure you follow the starting instructions in the chapter
”Driving”, especially in cold weather.
A number of symptoms and possible causes of engine prob-
lems can be found in the table on the next page.
Other possible causes of engine problems (starting or per-
formance) may be air in the fuel system, clogged fuel filter or
a vacuum in the fuel tank.
