operator ’s manual for further details.
(e) If you have no TOYOTA hand−held tester, connect the
positive (+) and negative (−) leads from the battery to the
fuel pump connector.
(See page MF−10)
(f) Check that there is pressure in the hose from the fuel filter.
HINT:
At this time, you will hear fuel return noise.
If there is no pressure, check these parts:
Fusible links (AM1 40A, AM2 30A, ALT 80A)
Fuses (EFI 15A, IGN 7.5A)
EFI main relay
Fuel pump
ECM
Wiring connections
(g) Turn the ignition switch to LOCK.
(h) Remove the TOYOTA hand−held tester.
2. CHECK FUEL PRESSURE
(a) Check that the battery voltage is above 12 volts.
(b) Disconnect the negative (−) terminal cable from the bat-
tery.
(c) Remove the union bolt and 2 gaskets, and disconnect the
fuel inlet pipe from the delivery pipe.

4. CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
(a) Check that the battery terminals are not loose or cor-
roded.
(b) Check the fusible link and fuses for continuity.
5. Delco Battery:
CHECK HYDROMETER
Green Dot visible:
Battery is adequately charged.
Dark (Green Dot not visible):
Battery must be charged.
Clear or Light Yellow:
Replace battery.
HINT:
There is no need to add water during the entire service life of
the battery.
6. INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cords
etc.
HINT:
Cracks on the ribbed side of the belt are considered acceptable.
If the belt has chunks missing from the ribs, it should be re-
placed.

When measuring the voltage, however, turn the ignition
switch OFF and turn off the electrical systems.
If the voltage is less than the specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
4. CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
(a) Check that the battery terminals are not loose or cor-
roded.
(b) Check the fusible link and fuses for continuity.
5. INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cords
etc.
HINT:
Cracks on the ribbed side of the belt are considered acceptable.
If the belt has chunks missing from the ribs, it should be re-
placed.
(b) Using a belt tension gauge, check the drive belt tension.
Belt tension gauge:
Nippondenso BTG 20 (95506−00020) or
Borroughs No. BT−33−73F
Drive belt tension:
New belt: 160 ± 20 lbf
Used belt: 100 ± 20 lbf
If necessary, adjust the drive belt tension.

HINT:
”New belt” refers to a belt which has been used less than
5 minutes on a running engine.
”Used belt” refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing the drive belt, check that it fits properly in
the ribbed grooves. Check with your hand to confirm that
the belt has not slipped out of the groove on the bottom
of the crank pulley.
After installing a new belt, run the engine for approx. 5
minutes and then recheck the tension.
6. INSPECT FUSES FOR CONTINUITY

CHARGE 7.5A
IGN 7.5A
7. VISUALLY CHECK GENERATOR WIRING AND LIS-
TEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the generator
while the engine is running.
8. CHECK CHARGING CIRCUIT WITHOUT LOAD
HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit according to the manufactuer’s instructions.
(a) If a tester is not available, connect a voltmeter and amme-
ter to the charging circuit as follows:
Disconnect the wire from terminal B of the generator
and connect the wire to the negative (−) terminal of
the ammeter.
Connect the test lead from the positive (+) terminal
of the ammeter to terminal B of the generator.
Connect the positive (+) lead of the voltmeter to ter-
minal B of the generator.
Ground the negative (−) lead of the voltmeter.
(b) Check the charging circuit as follows:
With the engine running from idling to 2,000 rpm, check
the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage:
At 25 °C (77 °F): 14.0 − 15.0 V
At 115 °C (239 °F): 13.5 − 14.3 V
If the voltage reading is greater than the standard voltage, re-
place the voltage regulator.
