That was a general comment on switches.  Like going from an old points ignition to an electronically switched Kettering system. The difference was as night and day.
Years ago I worked at Western Electric. We built central office switching equipment for all of the phone companies. When we tested frames with electronic cards, we removed the cards. Then the transistor and giant SCR were the most advanced pieces around. The first frame tested that had cards with chips came to us with the cards just pulled out of the connectors but not removed from the frame.
 
The shop inspectors had tested continuity with the cards close by the conductors. Continuity testing was then done with a door bell buzzer and a 4 1/2 volt battery. All of the cards were dead. Thousands down the drain. On the oscilloscope the divide by knob had to be twisted many times to find the top of those voltage spikes. Thousands of volts right next to the antennas built into each card. Mr. Tesla planned to broadcast electricity over great distances without wires. We proved he could do it at Western Electric. Even the loose tip on a soldering gun can be lethal. My point was that an unprotected switch can reprogram lots of things. Both when energized and when shut off.
 
We invented the darkness emitting diode.
Called the DED. Pronounced: Dead.
 
When I ran a crank trigger and one MSD for the front housing and a second for the rear housing, I had to run the primary wires along opposite sides of the engine to stop cross firing. Then I discovered inductive plug wires.

The thing is Lynn,  I had not changed any switches in at least 15+ min. of flight, did not even move the mixture knob, I have manual flaps, fixed landing gear & did not change the prop yet, that is what that flight was going to be for testing full cruise pitch speeds.  I have my complete schematic of the aircraft drawn out on a large poster board & will go through to look for ideas with Tracy's new info & guidelines.   David
