Incident Overview
While troubleshooting a fire warning indication with company maintenance control using the #2 VHF transceiver, the crew experienced several uncommanded 'kicks' of the yaw damper. The crew turned off the upper yaw damper, but did not turn off the lower yaw damper. They continued to experience 'kicks' although not as severe.
Flight and Landing
The flight departed and proceeded to Minneapolis, where it landed uneventfully.
Post-Incident Inspection
Inspection of the airplane after the incident revealed an open shield at the #2 VHF coax connector, which is located near the yaw damper control box. The connector was replaced and the airplane was returned to service.
