Mike,
Comco Ikarus ( <http://www.comco-ikarus.de/index_english.html>
http://www.comco-ikarus.de/index_english.html, I have no commercial
relations to them, but can recommend their excellent customer support)
sells
an electronic filter produced by Utz Schicke (producer of the Schicke
GR6
regulator for Rotax engines) which hooks directly to the AC wires of the
alternator. Whenever the alternator is in action (even with the
regulator
shut off), the Hobbs (or an other brand of hour meter) gets DC power and
is
active too. It costs 65 Euros.

What are chaps using to switch their hobbs timer on with engine start?
Is
there an alternative to the n/o oil pressure switch? - perhaps sensing
alternator output.
Thanks
