Alternator
The alternator installation is sensitive to incorrect connection,
therefore, always follow the instructions below:
Disconnecting
Q
Battery and alternator cables must not be disconnected while
the engine is running. A fault may then arise in the alternator
and the electronics.
Q
Disconnect and insulate the battery cables before carrying out
any work on the alternator equipment.
Battery connection
Q
The connecting terminals on the battery must under no
circumstances be confused. The respective pole studs have a
stamped-in (+) or (–) sign. If the cables are wrongly connected,
the alternator rectifier will be ruined immediately.
Q
When disconnecting batteries, first break the circuit using the
battery disconnect switch.
Alternator, belt tension
Check the condition of the belt for the first time at 250 hours
(also after replacement) and then every 2000 hours.
