7.2c Undo the two nuts and undo the screw (arrowed), then lift off the rear cover (Bosch alternator)

7.3a Undo the 5 screws (arrowed)

1 Remove the alternator (see Section 6) and place it on a clean workbench.

2 Remove the rear cover nuts, the screw and terminal insulator, and the rear cover (see illustrations).

3 Undo the 5 screws (Denso alternator) or

3 screws (Bosch alternator) and remove the brush holder and the regulator from the rear end frame (see illustrations).

4 Measure the exposed length of each brush (see illustration) and compare it to the minimum length listed in this Chapter's Specifications. If the length of either brush is less than the specified minimum, renew the brushes and brush holder assembly. Note: On some models, it may be necessary to solder the new brushes in place.

5 Make sure that each brush moves smoothly in the brush holder.

6 install the components in tne reverse order of removal, noting the following:

7 On Denso alternators, install the brush holder by depressing each brush with a small screwdriver to clear the shaft (see illustration).

8 Install the voltage regulator and brush holder screws into the rear frame.

9 Install the rear cover and tighten the nuts/ screw securely.

10 Install the terminal insulator and tighten it with the nut (where applicable).

11 Refit the alternator.

testing and overhaul jS

If the alternator is thought to be suspect, it should be removed from the vehicle and taken to an auto-electrician for testing. Most auto-electricians will be able to supply and fit brushes at a reasonable cost. However, check on the cost of repairs before proceeding as it may prove more economical to obtain a new or exchange alternator.

9 Starting system -

general information and precautions

General information

The function of the starting system is to turn over the engine quickly enough to allow it to start.

The system consists of the battery, the starter motor, the starter solenoid and the electrical circuit connecting the components. The solenoid is mounted directly on the starter motor (see illustration).

The solenoid/starter motor assembly is installed on the upper part of the engine, next to the transmission bellhousing.

When the ignition key is turned to the Start position, the starter solenoid is actuated through the starter control circuit. The starter solenoid then connects the battery to the starter. The battery supplies the electrical energy to the starter motor, which does the actual work of cranking the engine.

7.4 Measure the exposed length of each brush

The starter motor on a vehicle equipped with a manual transmission can be operated only when the clutch pedal is depressed; the starter on a vehicle equipped with an automatic transmission can be operated only when the transmission selector lever is in Park or Neutral.

Precautions

Always observe the following precautions when working on the starting system: a) Excessive cranking of the starter motor can overheat it and cause serious

7.3d Undo the 3 screws (arrowed) and remove the brush holder (Bosch alternator)

7.7 On Denso alternators, depress each brush with a small screwdriver to ease refitting damage. Never operate the starter motor for more than 15 seconds at a time without pausing to allow it to cool for at least two minutes.

b) The starter is connected directly to the battery and could arc or cause a fire if mishandled, overloaded or short-circuited.

c) Always detach the cable from the negative terminal of the battery before working on the starting system (see Section 3).

testing in vehicle ll

Note: Before diagnosing starter problems, make sure the battery is fully-charged.

1 If the starter motor does not turn at all when the switch is operated, make sure that the selector lever is in Neutral or Park (automatic transmission) or that the clutch pedal is depressed (manual transmission).

2 Make sure that the battery is charged and that all cables, both at the battery and starter solenoid terminals, are clean and secure.

3 If the starter motor spins but the engine is not cranking, the overrunning clutch in the starter motor is slipping and the starter motor must be renewed.

4 If, when the switch is actuated, the starter motor does not operate at all but the solenoid clicks, then the problem lies with either the battery, the main solenoid contacts or the starter motor itself (or the engine is seized).

5 If the solenoid plunger cannot be heard when the switch is actuated, the battery is faulty, the fusible link is burned (the circuit is open), the starter relay is defective or the starter solenoid itself is defective.

6 To check the solenoid, connect a jumper lead between the battery (+) and the ignition switch terminal (the small terminal) on the solenoid. If the starter motor now operates, the solenoid is OK and the problem is in the ignition switch, Neutral start switch or in the wiring.

7 If the starter motor still does not operate, remove the starter/solenoid assembly for disassembly, testing and repair. Take the starter motor to an auto-electrician for testing.

Most auto-electricians will be able to supply and fit brushes at a reasonable cost. However, check on the cost of repairs before proceeding as it may prove more economical to obtain a new or exchange motor. 8 If the starter motor cranks the engine at an abnormally slow speed, first make sure that the battery is charged and that all terminal connections are tight. If the engine is partially seized, or has the wrong viscosity oil in it, it will crank slowly.
