3. Anderson connectors for the battery boxes and bat-
tery chargers should have silicone grease applied to
the contacts only.
NOTE: Curing-type sealants might also be used to prevent
shorting and would be less messy, but would make
future pin removal more difficult.
When applied to electrical connections, dielectric grease
helps to prevent corrosion of electrical contacts and
improper conductivity between contacts from moisture
intrusion. Open and sealed connectors benefit from the
application of dielectric grease.
Dielectric grease shall be applied to all electrical connec-
tors at the time of connection (except those noted under
Exclusions).
Installation of Dielectric Grease
Before following these instructions, refer to excluded con-
nector types (See Exclusions below).
1. Use dielectric grease in a tube for larger connection
points or apply with a syringe for small connectors.
2. Apply dielectric grease to the female contact (fill it
approximately ½ full; see example below)
3. Leave a thin layer of dielectric grease on the face of
the connector
4. Assemble the connector system immediately to pre-
vent moisture ingress or dust contamination
5. Pierce one of the unused wire seals prior to assem-
bly if the connector system tends to trap air (i.e.
AMP Seal) and then install a seal plug.
Deutsch HD, DT, DTM, DRC Series
The Deutsch connector system is commonly used for
harsh environment interconnect. Follow the installation
instructions.
AMP Seal
The AMP Seal connector system is used on the Control
ADE Platform and Ground Modules.
Apply dielectric grease to the female contact. If trapped air
prevents the connector from latching, pierce one of the
unused wire seals. After assembly, install a seal plug (JLG
#4460905) in that location to prevent moisture ingress.
Note that seal plugs may be installed by the wire harness
manufacturer if an unused wire seal becomes compro-
mised (wire inserted in the wrong cavity during assembly
and then corrected).
