Drive belt tension: New belt 45-55 kg
Used belt 20-35 kg
If the belt tension is not as specified, adjust it.
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 while the engine is running.
5. INSPECT DISCHARGE WARNING LIGHT CIRCUIT
(a) Warm up the engine and then turn it off.

HINT: If a battery/alternator tester is available, connect
the tester to the charging circuit as per manufacturer's
instructions.
(a) If a tester is not available, connect a voltmeter and
ammeter to the charging circuit as follows:
• Disconnect the wire from terminal B of the alterna-
tor and connect it to the negative (-) lead of the
ammeter.
• Connect the positive ( + ) lead of the ammeter to
terminal B of the alternator.
• Connect the positive ( + ) lead of the voltmeter to
