Checking for loss of current
Check for loss of current before you check the rectifier regulator.
– Switch off the ignition and disconnect the ground wire from the
battery.
– Connect an ammeter between the ground wire and the negative pole
on the battery.
Set point value: max. 2 mA
– If the value is higher, look for the current consumers.
For example:
– a defective regulator/rectifier
– a defective multifunctional digital speedometer
– Creepage current in the socket connectors or in the ignition lock
NOTE: you will need to set the clock on the multifunctional digital
speedometer after the battery is connected.
Dismounting/replacing the battery

Checking the charging voltage / rectifier regulator
NOTE: the following figures only apply to fully charged batteries.
– Connect a voltmeter to both battery terminals.
– Start the engine and switch on the low beam.
– Rev the engine up to 5000 rpm and read the voltage.
Set point value: 14.0 – 15.0 V
If the measured value deviates significantly from the set point value:
– Check the socket connectors from the stator to the regulator rectifier
and from the regulator rectifier to the cable tree.
– Check the generator coils
– Replace the regulator rectifier
Checking the generator coils
– Disconnect the socket connector
(yellow) to the generator back to back for resistance.
Set point value: max 1.0 Ω at 20°C
– Check all three cables for short circuit to ground.
– Check both connectors for damage.
