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.
