–
Close the cover of the fuse box.
–
Install the front cover. (
–
Turn the key in the ignition switch to the position
–
Remove the rear fender. (
–
Connect the measuring leads of the multimeter to the battery terminals.
–
Measure the voltage while unloaded (no electrical consumer is switched on).
Battery voltage
unloaded:
»
If the displayed value does not meet specifications:
–
Recharge the battery.
600405-01
Condition
All plug-in contacts must be free of corrosion and firmly connected.
The battery must be ready to start but should not be fully charged. If the battery is fully
charged, start a number of times.
–
Remove the rear fender. (
–
Connect the multimeter. The black measuring lead is connected to the negative
terminal (ground) of the battery. Connect the red measuring lead to the positive
terminal.
–
Measurement while loaded (light switched on, brakes activated)

If the value displayed does not meet specifications:
–
Check the alternator. (

»
If the alternator is working properly:
–
Change the voltage regulator.
–
Switch off all power consumers and switch off the engine.
–
Remove the rear fender. (
–
Disconnect the negative (minus) cable of the battery.
–
Connect the multimeter between the negative cable and negative terminal of the
battery. Check the quiescent current.
Maximum quiescent current
»
If the measured value exceeds the specified value:
–
Check the plug-in connections and wiring harness.
–
To identify the power consumer, disconnect and reconnect the power con-
sumers from the wiring harness one by one while observing the quiescent
