Heh... we could do this all day. I had an airplane manual tell me one time.... "Failure of this unit is not expected/anticipated. Therefor, no provisions for replacement have been provided." Errr... thanks mr. engineer....
Or for anyone who has worked on Cat equipment one of the the last steps in diagnosing a problem with any electronic module:
The resistance is less than 5 ohms. The harness is not causing the problem. The main display module has failed.
Repair: It is unlikely that the main display module has failed. Exit this procedure and perform this procedure again.
