| Subject: | Wig wag revisited |
Working on the wig wag system using the B+C flasher.
What is going on inside that flasher?
I set it up on the bench with a DPDT switch. one side powers the flasher , the
other the right and left landing lights.
the set up works as is, and the bench ohm meter read 4.5 Kohm between the two
terminals.
The switched side of the flasher sees 14 volts when the landing lights are on,
but I don't think that can present a problem. Based on this I this I don't think
I need to set up the steering diode bridge, but thinking is not the same
as knowing.
Also an unsolicited plug: I bought the Dynon installation kit over a year ago.
This week when I actually wanted to use it, I found the D-sub crimper wouldn't
retract two of the pins. A call to B+C sent a new one out. I was actually
looking for advice, as the tool is over a year old, although never used, but they
went out of there way to help. ( do you think Rotax is going to extend there
warranty on the 912S even though it is still in the shipping box?)

The proof of the pudding is the repeatable
experiment. Give it a try and see what happens.
The schematic on page 3.0 of the suite of drawings
http://www.aeroelectric.com/PPS/Lighting/WigWag.pdf
. . . was developed to have a single switch where
down is OFF, mid is Wig-Wag and up is BOTH ON.
If you don't mind full down not being an off
position, then what you propose may be operationally
fine. It would help if you would post a schematic.

The blue tool is a universal 4-quadrant crimper
for machined pins. The knob on the handle sets
the crimp depth for various sizes of pins. You're
mission the suite of positioners that hold the
pin in the right location for applying the crimp.
Each style of pin has its own positioner.
The 59239 tool is for yellow PIDG terminals
and splices for 10-12 AWG wire.
The 59245 tool is for installing the center conductor
pin of some coax connector.
I don't recognize the parts in the other photo.
