Europa-List: Tacho problem

[Richard Iddon <riddon@sent.com>]

The Rotax analogue tacho on my 912S started flickering about on my last
flight for no apparent reason.  I have just test run the engine again
today and it has ceased working altogether. I have checked that there is
power going to it OK. 

I looked in the archive and find that some people have swapped a couple
of wires around and solved the flickering problem but I can't work out
which wires they swapped round. 

Can anyone enlighten me or offer any other solution to a duff tacho?
