I installed a Tiny Tach on my A65 w/Slick mags and initially I couldn't
understand how a coil of a few turns of wire wrapped around a shielded plug
wire was going to pick up a signal, but I followed the instructions anyway.
Well, it didn't, so I opened the shielding up with a scribe just enough
Maybe I suffer from dumb luck or perhaps my memory isn't so good, but I don't
recall having any issues with the one I had, although I did think the battery
was a bit short lived. When the battery dies, the accumulated engine time
resets to -0-, but otherwise was simple enough to remedy with a f
Don't waste your money on the Tiny Tach. I bought three or four of them and
finally gave up. I still have one in the box that displays something, but
it never showed a thing when hooked to an engine. Even if you finally get it
going, it won't last long, and may give you double or triple (or ha

When I read the reply from Jeff I remembered I the one on my Windless Trike.
In November I had an accident with my trike. Some of the stuff that was left
over from the wreck included a TinyTack. It worked well on the Rotax 503. I
removed it today but wonder what needs to be done to make
Hi Willie,
The Tiny Tach tacheometer has worked very well for me.It also records hours.The
end of a lead is simply wrapped around the nearest plug wire for about four
turns.Some have had poor results but remember when ordering to state whether

Tiny Tach makes a digital tach that uses induced voltage from a wire wrapped
around a spark plug lead as it's pick up. I used one on a Slick mag on a VW
with good results. I think you'll find a write up on Mark L's web pages about
him using a Tiny Tach on his Corvair as well. He had some issu
Not an expert on these things but it sounds like the little VDO was loading
the mag down, probably a low resistance movement or breaking down. 4 options
are to
1. try adding an in-line resistor of increasing value. If you get to the
stage where the engine is smooth and the tacho is still accurate y
I used a VDO rev counter with the pickup on the deadcut point of one Slick
Magneto. There are two on the Limbach. Since I removed the wire from the
Magneto the engine is running much smoother.
Now how can I measure the engine revs? There is no alternator on the motor.
Any ideas? Please help.
