Hi Bill, thanks.
May I dare ask if you or anyone has a schematic / wiring diagram of the box?
My airspeed indicator has 4 wires going into it, have played with a meter on
the indicator and on the wiring, was hoping to find a pressure activated
microswitch set-up. But its not, seems to be a circuit inside. From the
aircraft, 1 connector is earth, the other 3 has dv bus voltage on. SO in
the airspeed indicator there must be some kind of circuit. A friend has
offered to bring an oscilliscope to the aerie so we can try reverse engineer
the logic and get it bypassed.
Jorgen

Jorgen,
It is located under the glare shield, left front. If you stand in your seat,
lean over the windshield, (as if looking from outside - in) it is on the
left side torwards the lower front of windshield. Yellow like a fuel
pressure sensor. I hope I remembered that correctly.
Bill

Thanks but I'm OK on that ubless you have the "Special" one.
I have spare original indicator. (but can't use it. Without the right one
with the electrical connection the hydraulics don't work.

I think I still have the stock airspeed indicator someplace in a box. If you
want it I'll send it.

We have different airspeed indicators. I only have air hoses; no electric.
