Thanks Richard,
That's what I needed to know. The tach works with an input pulse down
to 6 volts, then quits, so I'm going to need a little amplification to
get it to work properly.

Bob,
the coil trigger signal is supposed to be a square pulse of 5V amplitude and 2ms duration. I used this on the single rotor at one time, and it worked great.
FWIW.
