4 hours.
Ran the twisted triple up the centerline for the AHRS and compass, made a new harness to connect them, and finished the harness for the AV2 backup instrument. The antenna inside the shop still dumps RF into the EFIS with the sensors connected, which is bad. I think it’s largely due to bounced energy off the metal stuff in the shop. Still, this solution is less wire, and therefore less weight. It also combines the AV2 sensor input with the Odyssey sensor input with no need for a Y-adapter, which has no place in an aircraft.
But at the end of the day I was utterly foiled. I don’t have a screwdriver long and thin enough to reach through the access holes to unscrew the DB9 connector on the back of the compass. So that’s going to have to wait.
