REFLECTOR: Progress

[Jack Prock]

Hi John,

This is the same that I have... I will have to look at the Rose EI schematic.

Maybe my problem is not a problem at all and it’s all in my head.... so many things running around
in there, and so few brain cells to handle them!!

Thanks

Jack

I have one Rose EI and the "mag" switch is wired identical to a regular mag switch.  When I turn the switch off, fancy electronics that I don't understand cut power to the EI.  Don't know if this will help.

  Hi,

  I am working on the final design of my electrical system and was wondering if anyone has used a standard 
  keyed ignition (OFF-Left-Right-BOTH) when set up with one mag and one electronic ignition system?

  Up until today, I was thinking that I could use a standard aircraft keyed switch, but I didn’t realize that the mag is shut off by
  grounding out one of the leads. This means that when the keyed switch is in the off position, the two terminals and the center
  post are actually connected. And when in the BOTH position, the two terminals and the center post are not connected. 

  I can think of a way to use the keyed switch... but the motion of the key turns from right to left, not left to right. I would just need
  to create a new label and use a relay for the Mag connection. This would have the added benefit of not having the mag wire
  anywhere near the radios to cut down on e-noise. I just don’t like the opposite key rotation.


  Are people with electronic ignitions using a two simple switches?  1) Elec-IGN   2) MAG   
  Do you have a key/lockset at all?

  Any input would be helpful.

  Thanks,

  Jack
