PRECAUTIONS
1. Check that the battery cables are connected to the correct
terminals.
2. Disconnect the battery cables when the battery is given a
quick charge.
3. Do not perform tests with a high voltage insulation
resistance tester.
4. Never disconnect the battery when the engine is running.

HINT:
wºNew beltº refer to a belt which has been used 5 minutes
or less on a running engine.
wºUsed beltº refers to a belt which has been used on a running
engine for 5 minutes or more.
wAfter installing a belt, check that it fits properly in the
ribbed grooves.
wCheck by hand to confirm that the belt has not slipped out
of the groove on the bottom of the pulley.
wAfter installing a new belt, run the engine for about 5
minutes and recheck the belt tension.
4. VISUALLY CHECK ALTERNATOR WIRING AND
LISTEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the
alternator white the engine is running.
6. INSPECT CHARGING CIRCUIT WITHOUT LOAD
HINT: If a battery/alternator tester is available, connect the
tester to the charging circuit as per manufacturer's instruc-
tions.
(a) If a tester is not available, connect a voltmeter and ammeter
to the charging circuit as follows:
wDisconnect the wire from terminal B of the alternator and
connect it to the negative H probe of the ammeter.
wConnect the positive (+) probe of the ammeter to terminals
B of the alternator.
wConnect the positive (+) probe of the voltmeter to terminal
B of the alternator.
wGround the negative (±) probe of the voltmeter. 5. INSPECT CHARGE WARNING LIGHT CIRCUIT
(a) Warm up the engine and then turn it off.
(b) Turn off all accessories.
(c) Turn the ignition switch to ºONº. Check that the charge
warning light is lit.
(d) Start the engine. Check that the light goes out.
If the light does not go off as specified, troubleshoot the
charge light circuit.
