Connector tags

Air Speed “AS” stamped metal tag in remote instrument box.

The remote instrument box includes three primary Telegon instruments, each with identical 5-pin AN connectors.  To avoid confusion, Link labeled them with small stamped metal tags.  “AS” air speed, “VS” vertical speed, and “ALT” altimeter.  Those little labels withstood the test of time.

We recently refurbished the turn and bank indicator regulator bellows for our Blue Boxes. The regulated vacuum output is supplied to a gyro inside the turn section of the turn and bank indicator.

Update December 1, 2020. The bellows refurbishing did the trick. The turn and bank indicator is now working. Yea!
