Unscrew screws. Take off microswitch. | |
Installation: Adjusting Microswitch: Press lever (4) -> lock in middle position. Release lever (4). | |
Measure resistance between pin 2 and pin 3. | |
Move microswitch up in direction of lever (5) until the microswitch switches continuity between pin 2 and pin 3. Resistance: approx. 0.1 to 0.2 ohm. Tighten switch and lock with a bolt cement*. Important! Never move the switch further up, since this would switch the second stage. * Source of Supply: BMW Parts | |
Function Test: Press lever (4) against the stop. Measure resistance between pin 3 and pin 1. Microswitch must have switched to continuity. Resistance: approx. 0.1 to 0.2 ohm. | |
Note: A damaged microswitch could result from excessive bearing play of lever (5) in the lock. Check bearing play of lever (5) and bearing play of the hollow-drilled shaft end, replacing the lock if necessary. |
