Generator
Before removing the generator you must disconnect
the ground cable from the minus pole of the battery
while the ignition is switched off. Do not disconnect
the generator while the engine is running, because
this may cause extremely high voltage peaks in the
vehicle wiring system ("Load Dump"), which could
possibly damage control units, radios or other elec-
tronic equipment.
When disassembling the battery cable, the B+-nut un-
derneath on the generator side may also be loosened.
This nut must in this case be retightened.
When connecting e.g. the battery cable to the terminal
of the generator you must make sure that the polarity
is correct (generator B+ to the + pole of the battery).
Mixing up the polarities by mistake causes short cir-
cuit and damage to the rectifier elements - the gener-
ator will be out of function.
The generator can only be operated with the battery
connected. Under special conditions emergency op-
eration without battery is permitted, the lifetime of the
generator is in such cases especially limited.
Plus and minus cables must be disconnected during
rapid charging of the battery or electric welding on the
vehicle.
When cleaning the generator with a steam or water jet
make sure not to direct the steam or water jet directly
on or into the generator openings or ball bearings. Af-
ter cleaning the generator should be operated for
about 1 - 2 minutes to remove any deposits of water
from the generator.
Starter motor
So-called jump starting (using an additional external
battery) without the battery connected is dangerous.
When disconnecting the cables from the poles high in-
ductivities (arcs, voltage peaks) may occur and de-
stroy the electrical installation.
For purposes like e.g. purging the fuel systems, start-
ers may be operated for maximum 1 minute without
interruption. Then you should wait for at least 30 min-
utes (cooling down) until trying again. During the 1
minute starting period this process should not be inter-
rupted.
Starter motors must not be cleaned with high pressure
steam cleaning equipment.
The contacts on starter terminals 30, 45, 50 must be
protected against unintended shorting (jump protec-
tion).
When replacing the starter the ring gear on the engine
flywheel must be checked for damage and its number
of teeth - if necessary replace the ring gear.
Always disconnect the battery before starting assem-
bly work in the starter area of the engine or on the
starter itself.
