Repair and Service Manual
Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings
Vehicle Moves When Selector Is Turned On
Cold temperatures also will diminish performance, by
reducing the power and efficiency of the batteries.

BATTERY CHARGER
The following tests are arranged sequentially according
to relative failure rate. If any test indicates a failed com-
ponent, replace that component and retest before pro-
ceeding to any later test procedure.
Make sure the charger is
turned off before work-
ing near capacitor termi-
nals. With the charger on, the transformer capacitor
terminals carry a very high voltage, which may cause
severe electrical shock.
Since each component can be tested individually, trou-
bleshooting is a simple task. The following is a list of
symptoms with their associated test procedures and
remedies:
Transformer Hums, But Batteries Will Not
Take A Charge
1. Check to insure that the batteries are properly con-
nected.
DO NOT allow the dis-
connected leads to come
in contact with battery
terminals during service procedures. Severe injury
due to electrical shock may result.
DC Circuit Continuity Test
1. Disconnect the AC supply cord from the wall outlet
and the DC output leads from the batteries. Remove
the charger from the vehicle.
2. Check the fuses on the charger front panel. If one or
more fuses have blown, refer to “Charger Fuse
Blows” for further tests. If the fuses are good, go to
next step.
3. Use a low voltage test light or Ohmmeter. Connect
the tester leads to the charger output leads and note
the reading.
4. Reverse the tester leads and check the output leads
again. The circuit should be complete in only one
direction.
5. If the circuit does not conduct in either direction and
fuses are good, individually check the DC output
leads, ammeter, diodes, and fuse connections (Each
may be checked with a continuity tester). If the Circuit
conducts in both directions, a short exists in the DC
circuit. Go to next step.
6. Check DC output leads for a short between the two
wires. If the problem still has not been located, proba-
bly one or more diodes has (have) shorted. Refer to
“Charger DC fuse Blows”, part (b), for continuity test-
ing procedures for diodes.
If the test shows that the DC circuit is good, a check
of the capacitor is necessary.
NEVER touch capacitor
terminals with uninsulat-
ed tools or probes, or
with any part of your body, because the high voltage
in the capacitor coil can cause serious injury due to
electrical shock.
Possible Causes
Remedy
Failed solenoid
Test, replace
Incorrect solenoid
Ensure proper replacement
parts are used. Consult a
part manual
Incorrect wiring
Consult proper wiring dia-
gram
Possible Causes
Remedy
Battery run down
Charge battery
Defective battery
Test battery, Replace as
needed.
Circuit breaker opens
Check current draw, rem-
edy as needed
Motor draw excessive
Check for drag, eliminate
friction.
Brake drag
Adjust brake
Possible Causes
Remedy
Improperly installed sole-
noid
Replace, install properly
Incorrect wiring
Rewire (consult proper wir-
ing diagram).
Incorrect solenoid
Ensure proper original
equipment replacement
parts are used. Consult a
current parts manual.
