Trouble Diagnoses
Before conducting an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and
suitable test probes are necessary for the test. The alternator can be checked easily by referring to the
Inspection Table.

Before starting, inspect the fusible link.

Use fully charged battery.

Note:

If the inspection result is OK even though the charging system is malfunctioning, check the B
terminal connection. (Check the tightening torque.)

When field circuit is open, check condition of rotor coil, rotor slip ring and brush. If necessary,
replace faulty parts with new ones.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate“CHARGE”warning lamp, if any of the following
symptoms occur while alternator is operating:

Excessive voltage is produced.

No voltage is produced.

Removal and Installation
1. Loosen lock bolt.
2. Remove RH undertray.
3. Loosen alternator mounting bolt and remove drive belt.
4. Remove lock bolt and adjust.
5. Remove harness connectors.
6. Remove alternator mounting bolt.
7. Support engine with jack, and remove front engine mounting
bolt.
8. Remove alternator.
Disassembly
REAR COVER
CAUTION:
Rear cover may be hard to remove because a ring is used
to lock outer race of rear bearing. To facilitate removal of
rear cover, heat bearing box section with a 200W soldering
iron.
Do not use a heat gun, as it can damage diode assembly.
REAR BEARING
CAUTION:

Do not reuse rear bearing after removal. Replace with a
new one.

Do not lubricate rear bearing outer race.
Inspection
ROTOR CHECK
1. Resistance test
Resistance: Refer to SDS (EL-63).

Not within the specified values ... Replace rotor.
2. Insulator test

Continuity exists ... Replace rotor.
3. Check slip ring for wear.
Slip ring minimum outer diameter:
Refer to SDS (EL-63).

Not within the specified values ... Replace rotor.
