Charging voltage / checking the voltage regulator-rectifier
NOTE: The values stated below apply only to fully charged batteries
(minimum charging level 90 %).
– Start the engine and switch on the low beam.
– Connect a voltmeter to both battery connections.
– Accelerate the engine to a speed of 5000 rpm and read off the
voltage.
Nominal value: 14.0 - 15.0 V
In the case of a significant deviation from the nominal value:
– Check the connector between the stator and the voltage regulator-
rectifier and the connector between the voltage regulator-rectifier
and the cable tree.
– Check the stator.
– Replace the voltage regulator-rectifier.
Removing the battery
– Remove the seat.
– Disconnect first the negative and then the positive pole of the
battery.
– Remove the bolts
1
and swing the battery support with the voltage
regulator-rectifier sideways.
– Remove the battery.
– When reinstalling the battery, connect the negative pole last.

Charging the battery
– Remove the battery and check the charging level. Use a voltmeter to
measure the voltage between the battery poles (off-load voltage).
– Accurate results can only be obtained if the battery has neither been
charged nor discharged during a period of 30 minutes preceding the
measuring.
– If the battery is empty, it can be recharged for a maximum period of
10 hours at 0.8 A and a maximum of 14.4 V.
