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.

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.

I have spare original indicator. (but can't use it. Without the right one with the electrical connection the hydraulics don't work. -----Original Message----- From: owner-l29-list-server@matronics.com [mailto:owner-l29-list-server@matronics.com] On Behalf Of Bill Sent: 19 February 2006 04:02 AM Subject: Re: RE: L29-List: Help - airspeed sensor --> L29-List message posted by: "Bill" I think I still have the stock airspeed indicator someplace in a box. If you want it I'll send it. ----- Original Message ----- From: "Jorgen Nielsen" Sent: Saturday, February 18, 2006 4:53 PM Subject: RE: L29-List: Help - airspeed sensor > --> L29-List message posted by: "Jorgen Nielsen" > > > So folks, no replies on this.

I only have air hoses; no electric. ________________________________ Message 4 _____________________________________ Time: 06:03:31 PM PST US From: "Roma L.
