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.

 Sorry for the delay.  I attempted to learn the express  software  for this, and simply could not get it off my clipboard.  so here is the  free hand version.  Sorry about the quality but I think it tells the  basics

Understand. What you've shown should function just fine.
