A review of switching systems is in order. Not only will the inductive load of the solenoid primary generate destructive voltages, as in a Kettering style field collapse, also the contactors in the solenoids can provide a dirty arcing when opening. Common switches as well may produce an electrically noisy opening. In modern electronics time periods, the operation of a common switch looks like a week long electrical storm. Diodes and capacitors across the contacts are used to silence such noise. Lynn E. Hanover In a message dated 8/22/2013 6:47:37 P.M. Eastern Daylight Time, hoursaway1@comcast.net writes:
Bobby, my map is ( was ) still set to factory with all bars in the center, after landing I thought to check EM2 screen with mapping bars & discovered half were still at center & half were all the way to the bottom/lean.

I just responded to Mark & mentioned that the only thing diff. from prev. 10 hrs. was I had both landing & taxi lights on this flight. David
