I ordered an Artex 345 ELT in December and received it in January, so I figured it was time to install it. It’s a pretty straightforward install, attached with just 4 bolts to a floor rib.
For the electrical, I ran a shielded 3-conductor wire out to the ELT as suggested in the Artex manual. I connected the wire shield to a pigtail and into the ground pin of the 15-pin connector.
The connector is the same as those used on the auto pilot servos, but not quite the same – instead of crimp-style pins, this connector uses solder lugs. The backshell is also less substantial than what Garmin provides.
