PWI, Inc. KAR 200 Dimming Issue Service Bulletin
Issued: January 2017
Effectivity: King Air 90, 100, and 200 series
Compliance – Optional: This change is not required as it is a purely aesthetic change.
Reason: This Service Bulletin is being issued to address the concerns of some customers that the KAR 200 dimmer switch does not produce a noticeable change.
Description: This Service Bulletin provides instructions and diagrams that show how to make the KAR 200 dimmer switch create a more noticeable dimming effect. The problem is that, for some customers, the dimmer switch is set at too low of a setting and this can be solved by using a soldering iron to move the wire attached to the middle of the resistor to the far right connector.
Warranty: There is no warranty associated with this Service Bulletin as it is a non-mandated change.
