Electrical System
Disconnect the power
Before any work is done on the electrical system, the
engine must be stopped and the power removed by
switching off the main switch(es). Any external power
supply for engine heaters, battery chargers or other
auxiliary equipment connected to the engine must be
disconnected.
Batteries
Batteries contain a highly corrosive electrolyte. Pro-
tect your eyes, skin and clothes during charging and
other handling of batteries. Always use protective
goggles and gloves.
If acid comes into contact with your skin, wash at once
with soap and a lot of water.
If you get battery acid in your eyes, flush at once with
a lot of cold water, and get medical assistance at
once.
Electric welding
Remove the positive and negative cables from the
batteries.
Then disconnect all cables connected to the alterna-
tor. Disconnect both connectors from the engine con-
trol module.
Always connect the welder earth clamp to the com-
ponent to be welded, and as close as possible to the
weld site. The clamp must never be connected to the
engine or in such a way that current can pass through
a bearing.
When welding is completed:
Always connect the
cables to the alternator
and engine control unit con-
nector before
reconnecting the battery cables.
