Don says it is not the right one for an A-4. [9/19/2019] Disassembled it, removing the portion which senses atmospheric pressure. On the face, there is a small motor and flag which says “Code Off.” With trial and error, discovered it will move by applying 12VDC directly, drawing about 47 mA. It won't move at less voltage, tested with 5V and 9V. text/html 2020-02-22T17:07:18+00:00 Anonymous (anonymous@undisclosed.example.com) http://stopstogo.com/dokuwiki/doku.php?id=projects:a4sim:componentinventory:aoa&rev=1582391238&do=diff Angle of Attack Indicator Disassembled the A-4 Angle of Attack indicator. It appears to be the real gauge from an A-4. It was quite complex. Keeping * Main dial, scale is 0 to 30 (units, not degrees, per Navy info) * “OFF” indicator. The Off indicator measures about 60 ohms. This can be indicated by apply 5V through a 220 Ohm Resistor.
