4. After the installation, the pigtail of the GMU 44 should mate with the aircraft wiring that is routed
through the wing. Due to the narrow thickness of the wingtip in this location, install chafe
protection between the pigtail of the GMU 44 and all surfaces of the wingtip that may come in
contact with the pigtail.
•
When routing the GMU 44 wiring with other power sources, ensure each power source
contains an adequate return ground. It is important to route the return ground with the
power wire to help cancel stray magnetic fields.
•
Route NAV light wiring as far as practical away from the GMU 44.
5. Refrain from installing any ferrous metals near the GMU 44, including the mounting screws and
nut plates used to attach the wingtip. Stainless steel fasteners are recommended.
