terminals. See Fig. 1. Select 10-amp scale.
3) Turn off all electrical accessories. Turn off interior
lights, underhood lamp, trunk light, illuminated entry, etc. To avoid
damaging ammeter or obtaining a false meter reading, all accessories
must be off before turning test switch knob to OFF position.
4) Turn test switch knob to OFF position to allow current to
flow through ammeter. If meter reads wrong polarity, turn test switch
to ON position and reverse leads. Turn test switch to OFF position.
Observe current reading. If reading is less than 2 amps, turn test
switch to ON position to keep electrical circuits powered-up.
5) Select low amp scale. Switch lead to the correct meter
position. Turn test switch to OFF position and compare results to
normal current draw. See the GENERAL MOTORS PARASITIC LOAD TABLE . If
current draw is unusually high for the vehicle's overall electrical
system, remove system fuses one at a time until current draw returns
to normal.
6) Turn test switch to ON position each time door is opened
or fuse is removed. Turn switch to OFF position to read current draw
value through meter. When the cause of excessive current drain has
been located and repaired, remove test switch and reconnect negative
battery cable to the negative battery terminal.

ON-VEHICLE TESTING
CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
DISABLING/ENABLING IGNITION & FUEL SYSTEMS
WARNING: To prevent engine from starting while performing tests,
always disable ignition and fuel systems.
Disabling Ignition & Fuel Systems
Remove Automatic Shutdown Relay (ASD) located in Power
Distribution Center (PDC). Refer to PDC cover for proper relay
location. PDC is located in engine compartment. On 5.9L diesel
engines, also disconnect fuel shutdown solenoid connector. Solenoid is
located behind upper intake manifold. See appropriate SYSTEM &
COMPONENT TESTING article in ENGINE PERFORMANCE section.
Enabling Ignition & Fuel Systems
When testing and/or repairs have been completed, verify
battery condition. Recharge battery as necessary, after starter tests
have been completed. Disconnect all test equipment. Install ASD relay.
On 5.9L diesel engines, reconnect fuel shutdown relay connector. On
all models, start engine several times to verify malfunction has been
corrected.
CRANKING TEST
NOTE: Ensure engine is at normal operating temperature. High
viscosity oil, extreme cold temperatures, or tight engine
will increase amperage draw.
1) Using a battery load tester, connect positive and negative
leads to battery. Connect inductive ammeter pick-up to positive
battery cable. Disable ignition and fuel systems. See
DISABLING/ENABLING IGNITION & FUEL SYSTEMS.
2) Ensure all lights and accessories are off. Place A/T in
Park position or M/T in Neutral position. Apply parking brake. Crank
engine and observe voltmeter reading. If voltage is more than 9.6
volts and cranking amperage draw is more than specified amps, proceed
to CIRCUIT RESISTANCE TESTS. See STARTER SPECIFICATIONS - CARS or
STARTER SPECIFICATIONS - TRUCKS.
3) If voltage is 12.5 volts or more and cranking amperage
draw is less than specified, check starter circuit components in the
following order:
starter solenoid, starter relay, starter relay circuit, park/neutral
position switch or transmission range sensor (A/T), clutch pedal
position switch (M/T), ignition switch, wiring harness and
connections.
CIRCUIT RESISTANCE TESTS
NOTE: If excessive resistance is not found in circuits being
tested, remove starter and proceed to BENCH TESTING.
Battery Connection Resistance Test
1) Disable vehicle ignition and fuel systems. See
DISABLING/ENABLING IGNITION & FUEL SYSTEMS. A voltmeter accurate to
one tenth of a volt will be needed for the following tests.

Dakota, Durango & Ram Pickup
WARNING: Deactivate air bag system before performing any service
operation involving steering column components. See
appropriate AIR BAG RESTRAINT SYSTEMS article. DO NOT apply
electrical power to any component on steering column without
first disconnecting air bag module. Air bag may deploy. Wait
at least 2 minutes after disconnecting negative battery cable
before servicing air bag system. System reserve capacitor,
integral to ACM, maintains air bag system voltage for about 2
minutes after battery is disconnected. Servicing air bag
system before 2-minute period may cause accidental air bag
deployment and possible personal injury.
DESCRIPTION
Turn signal, hazard flasher, headlight beam selector,
headlight flash-to-pass, windshield wipe, pulse wipe and windshield
wash systems use a common switch assembly (multifunction switch)
mounted within upper steering column housing.
Ignition switch and lock cylinder are incorporated into an
assembly attached to side of steering column. Ignition switch assembly
can be serviced as a separate unit, but requires removal of lock
cylinder.

until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
NOTE: For additional testing procedures, see appropriate CRUISE
CONTROL SYSTEMS and WIPER/WASHER SYSTEMS articles.
NOTE: For component locations, see COMPONENT LOCATIONS.
HORN RELAY
1) Remove horn relay from Power Distribution Center (PDC).
Use label on PDC cover to identify and locate relay. Check continuity
between relay terminals No. 87A and 30. See Fig. 1. If continuity does
not exist, replace relay. If continuity exists, go to next step.
2) Check continuity between relay terminals No. 30 and 87. If
continuity exists, replace relay. If continuity does not exist, check
resistance between relay terminals No. 85 and 86. If resistance is not
70-80 ohms, replace relay. If resistance is 70-80 ohms, go to next
step.
3) Using jumper wires, connect positive battery voltage to
