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 decommissioning of engines
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.
The works standard can be obtained from our After-Sales Service department in Nurem-
berg.
