Alternator Overhaul
NOTE: Do not remove the pulley unless the front bear-
ing needs replacement.
To loosen the pulley locknut, use the tools as shown. lf
necessary, use an impact wrench.

IRectifier Test
NOTE: The diodes are designed to allow current to pass
in one direction while blocking it in the opposite direc
tion. Since the alternator rectifier is made up of eight
diodes (four pairs), each diode must be tested for continuity in both directions with an ohmmeter that has diode
checking capability; a total of 16 checks.
'l. Check for continuity in each direction between- the B and P terminals.- E (ground) and P terminals.
All diodes should have continuity in only one direc-
tion.
2. lf any of the diodes fails, replace the rectifier assem-
bly. (Diodes are not available separatelv.)

Alternator Brush Inspection
2.
Remove the end cover, then take out the brush holder
by removing its two screws.
Measure the length of the brushes with a vernier
calrper.
Alternator Brush Length:
Standard (Newl:10.5 mm 10.41 inl
Service Limit: 1.5 mm {0.06 in)
lf the brushes are less than the service limit, replace
the alternator brush assemblv.

Rotor Slip Ring Test
1. Check the resistance between the slip rings.
There should be 1.8 - 3.0 ohms.
. lf resistance meets the specification, go to step 2
. lf resistance does not meet the specification,
replace the alternator.
SLIP RINGS
Check that there is no continuity between the slip
rings and the rotor or rotor shaft.
lf the rotor fails either continuity check, replace the
alternator.
ROTOR SHAFT

Stator Test
1. Check that there is continuity between each pair of
leads.
Check that there is no continuity between each lead
and the coil core.
It the coil fails either continuity check, replace the
alternator.

Alternator Belt Inspection and Adjustment
NOTE: When using a new belt, first adjust the deflectionor tension to the values for the new belt, then readjustthe deflection or tension to the values for the used beltafter running engine for five minutes.
Deflection methodi
Apply a force of 98 N (10 kgt,22lbll, and measure thedeflection between the alternator and crankshaft pulley.
Detlection:
Used Belt:8.5 - 11.5 mm (0.33 - 0.45 inlNew Beft: 5.5 - 8.0 mm 10.22 - 0.31 inl
NOTEr lf the belt is worn or damaged, replace it.
Measure here

Belt tension gauge m6thod:
Attach the belt tension gauge to the belt and measure thetension. Follow the gauge manufacturer's instructions.
Tension:
Used Belt:340 - /€0 N (35 - 50 kgf, 77 - 1r0 tbf)New Belt: 690 - 880 N (70 - 90 kgf, 150 - 200 tbt)
NOTE: lfthe belt is worn or damaged, replace it.

lf adjustment is necessary:
1. Loosen the mounting nut and the locknut.
2. Move the alternator to obtain the proper belt ten-
sion, then retighten the nuts.

Control Unit Input Test
SRS components are located in this area. Review the SRS component locations. precautions, and procedures in the SRS
section (241 before performing repairs or seryice.
'1. Remove the driver's dashboard lower cover and knee bolster {see section 20).
2. Disconnect the 'l4P connector from the control unit.
3. Inspect the connector and socket terminals to be sure they are all making good contact
lf the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
lf the terminals look OK, make the following input tests at the connector.- lf any test indicates a problem. find and correct the cause, then recheck the system.
- lf all the input tests prove OK, the control unit must be faulty; replace it.
