48—ELECTRICAL
SYSTEM
CHRYSLER
SERVICE MANUAL
b.
Clean and tighten cable connections.
c. Check solenoid switch for closing (con-
tacts jumper).
d. Adjust pinion clearance with plunger ad-
justing screw, with starter on bench.
e. Repair starter.
82.
STARTER FAILS
AND
LIGHTS
DIM
a.
Recharge or replace battery.
b.
Clean and tighten cable connections.
c. Check brush pigtails and coil leads for
grounds.
d. Replace grounded starter fields.
e. Check for armature rubbing on field poles.
83.
STARTER ARMATURE ROTATES BUT
PINION DOES NOT ENGAGE
a. Check arm shaft for rusting.
b.
Replace starter drive and adjust pinion
clearance.
c. Check solenoid plunger linkage.
d. Replace engine flywheel ring gear if bad.
84.
STARTER PINION JAMS IN RING GEAR
a. Replace drive. Replace flywheel ring gear.
Tighten starter mounting bolts securely when
replacing starter.
b.
Armature shaft bent. Replace armature
and check pinion and flywheel teeth.
GENERATORS
85.
GENERATOR FAILS TO CHARGE
a. Ground generator field terminal with en-
gine running at 1500 R.P.M. If it still fails to
charge, remove generator and repair. If gen-
erator charges with field grounded, remove
regulator, clean and adjust contacts or replace
regulator.
b.
Test for open circuit in field lead from
generator to regulator.
c. Test for grounded armature lead from
generator to regulator.
86.
LOW UNSTEADY CHARGING RATE
a. Adjust or replace drive belt.
b.
Test charging circuit resistance, cleaning
and tightening all loose connections.
c. Inspect generator brushes and commuta-
tor for wear, grease or commutator out of
round.
d. Test car ammeter.
87.
EXCESSIVE CHARGING RATE
a. Check regulator contacts for sticking and
for high setting of voltage regulator.
b.
Check for grounded field lead between
generator and regulator or for grounded field
terminal post by disconnecting field lead at
regulator with engine running at 1200 R.P.M.
This should cause generator to quit charging
if it does, regulator field circuit is grounded or
contacts stuck. If charge stops with field open,
disconnect field lead at generator. If charge
stops,
field lead is grounded, if not, remove gen-
erator and repair ground in generator field
terminal post or field lead to post.
88.
NOISY GENERATOR
a. Check pulley alignment.
b.
Check for electrical noise by grounding
armature terminal; if noise stops remove gen-
erator and inspect commutator and brushes.
c. Inspect bearing for wear or roughness.
d. Tighten pole shoe screws.
89.
PREMATURE FAILURE OF ARMATURE
a. Test regulator.
b.
Test for shorted cell in battery by using
capacity test.
REGULATORS
90.
REGULATOR CONTACTS OXIDIZED
a. Check resistance of ground circuit.
b.
Check field coils for short circuit.
c. Check for misalignment or improper air
gap adjustment of regulator contacts.
