Harness ELT D-Sub Plug Sealing
1)
After system operation is verified, with no errors displayed, it is suggested that the harness connector to the
ELT be sealed against moisture. This is best accomplished by encapsulating the exposed connections in
silicone sealant. ACR recommends Dow Corning® 4 Electrical Insulating Compound or an equivalent meeting
SAE AS-8660 (MIL-S8660C)
a)
Disconnect the remote switch harness D-Sub plug from the ELT.
b)
Separate the D-Sub housing halves.
c)
Inject sealant into the back side of the plug, so that sealant surrounds all exposed electrical connections
and the back of the plug.
d)
Reinstall the housing halves.
e)
Coat the mating pins/receptacles lightly with sealant.
f)
Re-connect the harness plug to the ELT.
C.
