Installation Of Dielectric Grease; Deutsch Hd, Dt, Dtm, Drc Series; Amp Seal - JLG 400S Service And Maintenance Manual

SECTION 7 - BASIC ELECTRICAL INFORMATION & SCHEMATICS
3. Anderson connectors for the battery boxes and battery
chargers should have silicone grease applied to the con-
tacts only.
NOTE: Curing-type sealants might also be used to prevent short-
ing 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 con-
ductivity between contacts from moisture intrusion. Open and
sealed connectors benefit from the application of dielectric
grease.
Dielectric grease shall be applied to all electrical connectors at
the time of connection (except those noted under Exclusions).

Installation of Dielectric Grease

Before following these instructions, refer to excluded connec-
tor 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 plug/male connector housing
which typically contains sockets contact/female termi-
nals (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 prevent
moisture ingress or dust contamination.
5. Pierce one of the unused wire seals prior to assembly 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 male contact. If trapped air pre-
vents the connector from latching, pierce one of the unused
wire seals. After assembly, install a seal plug (JLG #4460905) to
prevent moisture ingress.
Note that seal plugs may be installed by the wire harness man-
ufacturer if an unused wire seal becomes compromised (wire
inserted in the wrong cavity during assembly and then cor-
rected).
