I want to pick up the tachometer signal for another  project without affecting the current installation.  The Rotax installation  manual gives details of the pickup output, but I suspect that the 914 TCU signal  to the tacho may be a conditioned signal.  My engine is not running at the  moment so I cannot put my oscilloscope on it to test it.  I am particularly  interested in the peak voltage and whether it varies with RPM  when the TCU  is the source.

  

 Also what is the input resistance of the tacho  itself.

  

 Any electronics whizzes out there got any  ideas??

  

 regards,

  

 Mike

Hi Mike.



The tacho output is a normal pulse, about 10 V pp. It's documented in one of the manuals. I run it to the CG1 constant speed controller and the Dynon flightdeck. Both indications are exact. It's not coming from the TCU but a pickup coil like the ignition pickup coils. It's normally wired through the TCU, where one of the leads of the pickup coil is grounded. The internal resistance is low, adding more equipment does not matter.
