DODGE TOWN AND COUNTRY 2003 Service Manual

STANDARD PROCEDURE - TESTING FOR A
SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
(1) Refer to the wiring diagrams and disconnect or
isolate all items on the suspected fused circuits.
(2) Replace the blown fuse.
(3) Supply power to the fuse by turning ON the
ignition switch or re-connecting the battery.
(4) Start connecting or energizing the items in the
fuse circuit one at a time. When the fuse blows the
circuit with the short to ground has been isolated.
STANDARD PROCEDURE - TESTING FOR A
VOLTAGE DROP
(1) Connect the positive lead of the voltmeter to
the side of the circuit closest to the battery (Fig. 9).
(2) Connect the other lead of the voltmeter to the
other side of the switch, component or circuit.
(3) Operate the item.
(4) The voltmeter will show the difference in volt-
age between the two points.

CONNECTOR
REMOVAL
(1) Disconnect battery.
(2) Release Connector Lock (Fig. 10).
(3) Disconnect the connector being repaired from
its mating half/component.
(4) Remove the dress cover (if applicable) (Fig. 10).
(5) Release the Secondary Terminal Lock, if
required (Fig. 11).
(6) Position the connector locking finger away from
the terminal using the proper special tool. Pull on
the wire to remove the terminal from the connector
(Fig. 12).
INSTALLATION
(1) Insert the removed terminal in the same cavity
on the repair connector.
(2) Repeat steps for each terminal in the connec-
tor, being sure that all wires are inserted into the
proper cavities. For additional connector pin-out
identification, refer to the wiring diagrams.
(3) When the connector is re-assembled, the sec-
ondary terminal lock must be placed in the locked
position to prevent terminal push out.
(4) Replace dress cover (if applicable).
(5) Connect connector to its mating half/compo-
nent.
(6) Connect battery and test all affected systems.

DIODE
REMOVAL
(1) Disconnect the battery.
(2) Locate the diode in the harness, and remove
the protective covering.
(3) Remove the diode from the harness, pay atten-
tion to the current flow direction (Fig. 13).
INSTALLATION
(1) Remove the insulation from the wires in the
harness. Only remove enough insulation to solder in
the new diode.
(2) Install the new diode in the harness, making
sure current flow is correct. If necessary, refer to the
appropriate wiring diagram for current flow (Fig. 13).
(3) Solder the connection together using rosin core
type solder only.Do not use acid core solder.
(4) Tape the diode to the harness using electrical
tape. Make sure the diode is completely sealed from
the elements.
(5) Re-connect the battery and test affected sys-
tems.
TERMINAL
REMOVAL
(1) Follow steps for removing terminals described
in the connector removal section.
(2) Cut the wire 6 inches from the back of the con-
nector.
INSTALLATION
(1) Select a wire from the terminal repair kit that
best matches the color and gage of the wire being
repaired.
(2) Cut the repair wire to the proper length and
remove one±half (1/2) inch of insulation.
(3) Splice the repair wire to the wire harness (see
wire splicing procedure).
(4) Insert the repaired wire into the connector.
(5) Install the connector locking wedge, if required,
and reconnect the connector to its mating half/compo-
nent.
(6) Re-tape the wire harness starting at 1±1/2
inches behind the connector and 2 inches past the
repair.
(7) Connect battery and test all affected systems.

WIRE
STANDARD PROCEDURE - WIRE SPLICING
When splicing a wire, it is important that the cor-
rect gage be used as shown in the wiring diagrams.
(1) Remove one-half (1/2) inch of insulation from
each wire that needs to be spliced.
(2) Place a piece of adhesive lined heat shrink tub-
ing on one side of the wire. Make sure the tubing will
be long enough to cover and seal the entire repair
area.
(3) Place the strands of wire overlapping each
other inside of the splice clip (Fig. 14).
(4) Using crimping tool, Mopar p/n 05019912AA,
crimp the splice clip and wires together (Fig. 15).(5) Solder the connection together using rosin core
type solder only (Fig. 16).
CAUTION: DO NOT USE ACID CORE SOLDER.
(6) Center the heat shrink tubing over the joint
and heat using a heat gun. Heat the joint until the
tubing is tightly sealed and sealant comes out of both
ends of the tubing (Fig. 17).
