Alternator
The alternator is maintenance-free.
Nevertheless, it must be protected against dust and, above all, against moisture.
In order to avoid damage to the alternator, observe the following instructions:
While the engine is running
D
Do not de-energize the main battery switch!
D
Do not disconnect the battery or pole terminals or the cables!
D
If, durig operation, the battery charge lamp suddenly lights up, stop the engine im-
mediately and remedy the fault in the electrical system!
D
Do not run the engine unless the battery charge control is in satisfactory order!
D
Do not short-circuit the connections of the alternator with those of the regulator or said
connections with ground, not even by briefly bringing the connections into contact!
D
Do not operate the alternator without battery connection!

Temporary anti-corrosion protection according to MAN works norm M 3069 is required for
engines which are to be put out of service for fairly long periods.
