Starting System
Starter Test (cont'dl
Check Cranking rpmr
Engine speed during cranking should be above 1OO rpm.
lJ speed is too low, check for:
a Loose batlery or starter terminals
a Excessively worn starter brushes
a Open circuit in commutator segments
a Dirty or damaged helical spline or drive gear
a Defective drive gear overrunning clutch
Check Starter Disengagement:
Press the clutch pedal all the way in (M/T), turn rhe igni
tion switch to "lll" and release to "11".
The starter drive gear should disengage from the flywheel
or torque converter ring gear when you release the key.
It the drive gear hangs up on the flywheel or torque con-
verter ring gear, check for:
a Solenoid plunger and switch mallunction
a Dirty drive gear assembly or damaged overrunning
clutch
5. Check for an open in the BLK/WHT wire circuit be
tween the starter and ignition switch, and con-
necrors,
6. Check the ignition switch (see page 23-71).
7. On cars with automatic transmission, check the A/Tgear position switch (neutral position switch) and
connector. On cars with manualtransmission, check
the starter cut relay, clutch interlock switch, and
connectors.
NOTE: Check the No. 42 (40 A) fuse in the under,hoodfuse/relay box for the starter cut relay.
Check Jor Wear and Damage:
The starter should crank the engine smoothly and stead,ily. lf the starter engages, but cranks the engine errati
cally, remove it. Inspect the starter, drive gear, andllywheel or torque converter ring gear lor damage.
a Check the drive gear overrunning clutch for binding
or slipping when the armature is rotated with the drivegear held. Replace the gears i{ damaged.
Check CJanking Voltage and Current Draw:
Cranking voltage should be no less than 8.O volts.
Current draw should be no more than * amperes.* 1.2 kW: 27O A
1 .4 kW: 360 A
It cranking voltage is too low, or current draw too high,check for:
a Dead or low charged batterya Open circuit in starter armature commutator segmentsa Starter armalure dragging
a Shorted armature windinga Excessive drag in engine
