Checking the charging voltage
NOTE: the following figures only apply to fully charged batteries
(charging condition at least 90 %).
– Connect a voltmeter to both battery terminals.
– Start the engine.
– Rev the engine up to 5000 rpm and read the voltage.
14.5 V
If the measured value deviates significantly from the setpoint value:
– Check the socket connectors from the stator to the voltage regulator
and from the voltage regulator to the wiring harness.
– Check the stator.
– Replace the voltage regulator.
Checking for loss of current
Check for loss of current before you check the voltage regulator.
– Disconnect the ground wire from the battery.
– Connect an ammeter between the ground wire and the negative
terminal on the battery.
– If this value is higher than specified, look for the power consumers.
