Checking the capacitor
en-circuit current
Preparatory work
-
Switch off all power consumers and switch off the engine.
-
Remove the seat.
Main work
-
Disconnect the negative cable of the battery.
-
Measure the current between battery ground (-) and the negative cable.
•
Info
I
The value of the quiescent current applies only to vehicles in the original
state, i.e. without additional power consumers.
I
Maximum open-circuit current
If the measured value is greater than the specified value:
-
Disconnect the voltage regulator from the wiring harness and perform the
measurement again.
-
Check the capacitor.
Finishing work
-
Connect the negative cable of the battery.
-
Mount the seat.
Condition
The battery is disconnected.
-
Remove the capacitor.
-
Discharge the capacitor by bridging the two contacts.
-
Connect the capacitor with a 12 V test lamp on one connector and connect it to
the battery as shown in the figure.
Info
•
I
As the charge of the capacitor increases, the test lamp becomes dimmer.
,,
The lamp lights up for: 0.5 ... 2.0 s
The capacitor is functional.

,,
The lamp lights up for: < 0.5 s
Change the capacitor.
,,
The lamp lights up for: > 2.0 s
Change the capacitor.
-
Discharge the capacitor with a 12 V test lamp as shown in the figure.
