Troubleshooting Bendix Fast Idle/Cruise Control on 89 35FC 3208 ATAAC

[Howard O. Truitt]

Scott,
My Tachometer went out last week on a trip and my CC quit at the same time. The
CC must work off the Tach. Are you having trouble with your Tach.

Is fast idle on all models handled through the CC? My fast idle
switch works fine, but my CC is inop on the road.
