OK, my stupid factor is in high gear today. I'm having difficulty with the flap switch wiring as shown on 6B-20. I've attached a copy. Somebody help me out, as I can't seem to get it right. I see that the black wire from the flap motor goes to the #1 lug. Red goes to number 3 lug. Ground goes to #2. Hot wire from the buss goes to 5 Beyond that I get confused. I've attached the diagram.
Thanks in advance.

Grant,
I noticed I was flying slightly nose up in cruise in my 701. I dropped the flaperons a small amount and the nose came down and I picked up about 2 mph.

OK, the note above the schematic that says “Circuit is shown for flaps up: the worm gear is in the retracted position shutting off the up limit micro sw”. But the schematic shows the up-limit switch closed, not open. So they contradict each other. I think the schematic either shows the system in the full down position or is wrong. It all depends on which way the motor turns when red is positive or black is positive. Since I only currently have the new-style sealed flap motor I can’t test this for you. But as shown if you moved the toggle to connect lugs 1-2 and lugs 4-5 nothing will happen because the “down” switch is open, breaking the circuit from lug 4. If you move the toggle to connect lugs 2-3 and 5-6 the motor will turn until the “up” switch gets hit and breaks the circuit from lug 6.
Anyway the red wire goes to lug 3 on the toggle switch AND the common lug on the “down” limit micro-switch (the one towards the rear of the plane and away from the electric motor). Likewise the black wire goes to lug 1 and the “normally closed” lug (marked “NC”) on the flap-up limit switch (towards the front of the plane and the electric motor)
In all four wires have to run from the flap actuator to the toggle switch on your panel. The remaining two wires are:
- a wire from the common lug on the “up” limit switch to lug 6 on the toggle on the panel
- a wire from the normally closed (“NC”) lug on the “down limit” switch to lug 4 on the toggle on the panel.
BE VERY CARFUL with the screw terminals on the limit switches. The plastic cases are fragile. Don’t try to bend the lugs.
Basically for either direction the toggle on the panel and the appropriate limit switch are wired in series. So the motor will only move as long as both are closed. Release the toggle or hit the limit switch and the motor stops.
Test wire half the system (like just the “moving down” direction) and try it with a car battery. You can flip the micro-switch by hand before the traveler reaches it to see if the switch will actually stop the travel.
