I am finally ready to start hooking up wires on my Zenith 801 with Lycoming O-360a1a.  I have a Aveo E-1 and MaxFlight on my panel and need an electronic RPM pickup for the Lycoming.  My ultralight (Quicksilver GT400) was very simple to wire up as it had a pulse wire from the electronic ignition already.  No electronic ignition on this old Lycoming (Bendix mags).  Any suggestions?

  You can read rpm from across the p-lead connections of an

  operating magneto. When you say 'electronic RPM pickup' I

  would hope that your instrument defines what that means.



  Many electronic tachs have been built and marketed that

  will read RPM from a magneto. Others depend on "real"

  5 or 12v square waves from a hall effect device (some will

  read the spinning magneto magnet right through the housing).

  Still others may be unique pick-up technologies that expected

  something way out of the mainstream.



  What do the instructions for your instrument say?

Jay,

Advanced Flight Systems has a tach sensor that screws into the mag.  Another way is to purchase a tach drive sensor that screws into the tach drive on the engine.  Check Aircraft Spruce or Wicks for this.  Don

 Hi Jay-



 >... need an electronic RPM pickup for the Lycoming...



 Westach makes a unit that screws right on to the tach drive and (I

believe) outputs a 5V pulse train.
