NISSAN PRIMERA 1999 Electronic Repair Manual

YOKE CHECK
Magnet is secured to yoke by bonding agent. Check magnet to
see that it is secured to yoke and for any cracks. Replace mal-
functioning parts as an assembly.
Holder may move slightly as it is only inserted and not bonded.
CAUTION:
Do not clamp yoke in a vice or strike it with a hammer.
ARMATURE CHECK
1. Continuity test (between two segments side by side).

No continuity ... Replace.
2. Insulation test (between each commutator bar and shaft).

Continuity exists. ... Replace.
3. Check commutator surface.

Rough ... Sand lightly with No. 500 - 600 emery paper.
4. Check diameter of commutator.
Commutator minimum diameter:
Refer to SDS (EL-52).

Less than specified value ... Replace.

Assembly
Apply high-temperature grease to lubricate the bearing, gears
and frictional surface when assembling the starter.
Carefully observe the following instructions.
PINION PROTRUSION LENGTH ADJUSTMENT
Clearance“l”
With pinion driven out by magnetic switch, push pinion back to
remove slack and measure clearance“l”between the front edge
of the pinion and the pinion stopper.

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.
