DESCRIPTION
Bosch, Melco and Mitsubishi starters use a planetary gear
train that transmits power from starter motor to pinion shaft. Six
permanent magnets (Bosch and Melco starters) or 4 permanent magnets
(Mitsubishi starters) are used, eliminating potential field wire-to-
frame short circuits.
Nippondenso starter is a 4-field, 4-brush, 12-volt motor with
a solenoid mounted within the housing. The unit has a 2-to-1 reduction
gear set in a die cast aluminum housing. Starter has serviceable gear
and clutch assembly only. If starter solenoid fails, entire starter
motor must be replaced.
All models use a starter relay in starter circuit between the
battery and starter solenoid terminal. Automatic Transmission (A/T)
equipped vehicles use a Park/Neutral Position (PNP) switch or a
Transmission Range (TR) sensor to provide ground path for the starter
relay. Manual Transmission (M/T) equipped vehicles use a clutch pedal
position switch to provide battery voltage from ignition switch to the
starter relay. See WIRING DIAGRAMS.

TROUBLE SHOOTING
NOTE: See TROUBLE SHOOTING article in GENERAL INFORMATION.

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.

STARTER RELAY CIRCUIT TEST
NOTE: Perform STARTER RELAY TEST before testing starter relay
circuit.
1) Ensure battery is fully charged. Remove starter relay from
Power Distribution Center (PDC). Refer to PDC cover for proper relay
location. PDC is located in engine compartment.
2) Connect a jumper wire between starter relay socket
terminal No. 30 and terminal No. 87. See Fig. 1 or 2. If engine does
not crank, go to SOLENOID TEST under BENCH TESTING. If engine cranks,
go to next step.
3) Turn ignition on. Check voltage between ground and starter
relay socket terminal No. 30. If battery voltage is not present,
repair open in circuit between starter relay socket and battery. If
battery voltage is present, go to next step.
4) Check voltage between ground and starter relay socket
terminal No. 86 with ignition switch in START position and clutch
pedal depressed (if equipped with M/T). If battery voltage is present,\
circuit is okay. Go to step 6) if equipped with M/T or step 7) if
equipped with A/T. If battery voltage is not present, repair open in
circuit between ignition switch and starter relay socket (A/T) or go
to next step (M/T).
5) Unplug wiring connector from clutch position switch
mounted on clutch pedal bracket. Connect jumper wire between clutch
position switch connector terminals. Recheck for voltage at starter
relay socket terminal No. 86 with ignition switch in START position.
If battery voltage is present, check clutch position switch adjustment
(if applicable). Adjust switch as necessary. If switch adjustment is
okay, check clutch position switch. See CLUTCH POSITION SWITCH TEST.
If battery voltage is not present, repair wiring between ignition
switch and starter relay socket as necessary.
6) On M/T models, connect voltmeter negative lead to starter
relay socket terminal No. 85 and positive lead to terminal No. 86.
Turn ignition switch to START position and depress clutch pedal. If
battery voltage is present, starter relay socket ground circuit is
good. Replace faulty starter relay. If battery voltage is not present,
repair ground wire circuit.
7) On A/T models, connect voltmeter negative lead to starter
relay socket terminal No. 85 and positive lead to terminal No. 86.
Ensure transmission gear selector is in Park or Neutral position.
Ground circuit runs through Park/Neutral Position (PNP) switch or
Transmission Range (TR) sensor on transmission. Turn ignition switch
to START position. If battery voltage is present, starter relay socket
ground circuit is good. Replace faulty starter relay.
8) If battery voltage is not present, check PNP switch or TR
sensor for loose or damaged connections. Also, check ground to PNP
switch or TR sensor. Repair as necessary. If connections and ground
are okay, check PNP switch or TR sensor. See PARK/NEUTRAL POSITION
(PNP) SWITCH & TRANSMISSION RANGE (TR) SENSOR TEST.
PARK/NEUTRAL POSITION (PNP) SWITCH & TRANSMISSION RANGE (TR)
SENSOR TEST
NOTE: Transmission Range (TR) sensor may be also known as
Park/Neutral Position (PNP) switch or Park/Neutral switch.
NOTE: The following test is for Caravan, Ram Van, Ram Wagon and
Voyager with 3-speed transmission. All other models are
equipped with a Transmission Range (TR) sensor. If TR sensor
or sensor circuit is defective, see appropriate NTC test in
appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE
section.
