Electrical system
The engine must be switched off and the power
disconnected using the master switch or battery
master switch before working on the electrical
system. External power supplies to extra equip-
ment on the engine must also be disconnected.
IMPORTANT!
Always use Scania spare parts for the fuel and
electrical systems. Scania spare parts are de-
signed to minimise the risk of fire and explosion.
Electric welding
IMPORTANT!
When carrying out welding work on and near the
engine, disconnect the battery and alternator
leads. Pull out the multi-pin connector for the en-
gine control unit as well.
Connect the welding clamp close to the compo-
nent to be welded. The welding clamp must not
be connected to the engine, or so that the current
can cross a bearing.
When welding is finished:
1.
Connect the alternator and control unit ca-
bles first.
2.
Then connect the batteries.
