DIAGNOSIS AND TESTING
TROUBLE DIAGNOSIS GUIDE
BATTERY LOW IN CHARGE
Indications of a battery low in
charge are slow cranking, hard start-
ing, and headlights dim at engine idle
speed. Causes are:
I. The alternator belt worn, or
loose and slipping over the pulley.
2. The battery in such poor con-
dition that it will not hold or take a
charge.
3. The alternator not producing
its rated output.
4..
Regulator unit out of adjust-
ment, and excessive resistance in the
alternator-to-battery circuit or in the
battt::ry-to-ground circuit.
First chock the alternator belt ad-
justment and condition.
RECHARGE OR REPLACE
BATTERY
Perform a battery Before Charge
Test (page 13-6). Replace the bat-
tery if the test indicates it is worn
out or under capacity. If the battery
capacity is normal, proceed as fol-
lows•
TEST ALTERNATOR OUTPUT
Test the alternator output (page
13-2:
to determine if the alternator
is at fault. If the output is normal
or greater than the rating of the al-
ternator, proceed with an alternator
regulator test under the heading "Test
Alter.nator Regulator." If the output
is low proceed as follows: -
ALTERNATOR OUTPUT LOW
Connect a heavy jumper wire from
the battery ground post to the alter-
nator ground terminal. Repeat the
alternator output test. If the output
now reaches or exceeds rated output,
either the alternator or the battery is
not properly grounded to the engine
frame. Replace the battery-to-ground
cable if it is corroded or partially
broken. Clean the cable connections
at the battery and engine, and tighten
the connections. Tighten the alter-
nator mounting bolts.
If the alternator output is still less
than normal, the alternator output
could be low due to an open or short
circuit in the field, stator, brushes, or
brush holders, or the brushes can be
worn too short or may be sticking in
the brush holder and not making
good contact on the slip rings. Re-
move the alternator for repair.
