Electrical equipment
Alternator
The alternator is fitted with integral silicon rectifiers.
A transistorized regulator mounted on the alternator limits the alternator voltage. The al-
ternator should not be operated except with the regulator and battery connected in circuit
to avoid damage to the rectifier and regulator.
The alternator is maintenance-free. Nevertheless, it must be protected against dust and,
above all, against moisture.
Operate the alternator according to the instructions given in the chapter “Commis-
sioning and operation”.
Starter motor
The sliding-gear starter motor is flanged to the rear of the flywheel housing on the right-
hand side.
As part of every engine overhaul, the starter pinion and ring gear should be cleaned with
a brush dipped in fuel and then a coat of grease should be applied again.
Always protect starter motor against moisture.
Warning:
Always disconnect the battery earth cable before starting work on the electrical sys-
tem. Connect up the earth cable last, as there is otherwise a risk of short-circuits.
