Starting System
Starter Test (cont'dl
Check lor Wear and D8mage
The starter should crank the engine smoothly and
steadily. lf the staner engages, but cranks the engine
erratically, remove it, and inspect the starter drive gear
and torque converter ring gear or flywheel ring gear for
oamage.
Check the drive gear overrunning clutch for binding or
slipping when the armature is rotated with the drive
gear held. lf damaged, replace the gears.
Check Cranking Voltage and Current Draw
Cranking voltage should be no less than 8.7 volts on Ay'T
models, and 8.0 volts on M/T moders.
Current draw should be no more than 230 amperes on
A,/T models, and 200 amperes on M/T models.
lf cranking voltage is too low, or current draw too high,
check for:
. dead or low battery.
a open circuit in starter armature commutator seg,
ments.
. starter armature dragging.
. shorted armature winding.
. excessive drag in engine.
Check Cranking rpm
Engine speed during cranking should be above 100 rpm.
lf speed is too low, check for:
a loose baftery or starter terminals.
. excesslvely worn staner brushes
. open circuit in commutator segments.
. dirty or damaged helical splines or drive gear.
a defective drive gear overrunning clutch.
Check Starter Disengagement
With the shift lever in @ or @ position (A,iT) or with the
clutch pedal depressed {M/T). turn the ignition switch to
START (lll). and release to ON (ll).
The starter drive gear should disengage from the torque
converter ring gear or flywheel ring gear when you
release the key.
lf the drive gear hangs up on the torque converter ring
gear or flywheel ring gear, check for
. solenoid plunger and switch malfunction.
. dirty drive gear assembly or damaged overrunning
clutch.
Starter Solenoid Test
1. Check the hold-in coil for continuity between the S
terminal and lhe armature housing (ground). The
coil is OK if there is continuity.
