Checking the lead

Unplug the connector:

Generator 2

Connect test lamp 86 11 857 between pin 1 of the female connector and a good grounding point.

Start the engine and run it at idling speed.

Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.

The test lamp should light.

Is the function correct?
