|
|
Folks,
I bought an Artex 1000 ELT and just soldered the wires to the supplied D-Sub connector. Artex also supplied two sealant strips. You can see them in the bottom center of this photo that I took:
[img]cid:ii_j4rqhhg00_15d15711ee658572[/img]
The instructions read:
Quote: | 4) Install two sealant strips (850-0814) into the receptacle of the ELT. Peel the adhesive backing from the strips and stack one on top of the other. Push the pins through the strips. |
If I understand that correctly, ACR wants me to mush the sealant strips onto the male D-Sub connector on the ELT. Do you agree?
Then, after system operation is verified, ACR's instructions call for disassembling the D-Sub connector and injecting sealant (ACR recommends Dow Corning® 4 Electrical Insulating Compound) "into the back side of the plug, so that sealant surrounds all exposed electrical connections and the back of the plug." The instructions also state, "Coat the mating pins/receptacles lightly with sealant."
Is this the dielectric grease that I have seen discussed several times on this list? Why would I use this for a connector that will be inside the airplane, never exposed to weather?
Thanks,
-- Art Z.

Who knows what conditions will exist after the ELT is called upon to transmit an emergency signal? Best to follow manufacturer's directions.
