2.Check that the battery cables are connected to the correct terminals.
3.Disconnect the battery cables when the battery is given a quick charge.
4.Never disconnect the battery while the engine is running.
5.Check that the charging cable nut is tightly installed on terminal B of the generator.

CHARGING SYSTEM (for DENSO Made) > ON-VEHICLE INSPECTION
CAUTION:
If the battery is weak or if the engine is difficult to start, recharge the battery and perform inspections again before returning the vehicle to the customer.
1. CHECK BATTERY CONDITION
1.Check the battery for damage and deformation. If severe damage, deformation or
leakage is found, replace the battery.
2.Check the volume of electrolyte in each cell.
1.For batteries that are maintenance-free:
?If the electrolyte volume is below the lower line, replace the
battery.
?If the electrolyte volume is above the lower line, check the battery
voltage when cranking the engine.
?If the voltage is less than 9.6 V, recharge or replace the battery.
HINT:
Before checking the battery voltage, turn off all the electrical systems (headlights, blower motor, etc.).
2.For batteries that are not maintenance-free:
?If the electrolyte volume is below the lower line, add distilled
water to each cell. Then, recharge the battery and check the
electrolyte specific gravity.
Standard specific gravity:
1.25 to 1.29 at 20 °C (68°F)
If the electrolyte volume is above the lower line, check the battery voltage
when cranking the engine. If the voltage is less than 9.6 V, recharge or
replace the battery.
HINT:
Before checking the battery voltage, turn off all the electrical systems (headlights, blower motor, rear defogger, etc.).
2. CHECK BATTERY TERMINAL AND FUSE
1.Check that the battery terminals are not loose or corroded.
If the terminals are corroded, clean the terminals.
2.Measure the resistance of the H-fuse and fuses.
Standard resistance:
Below 1 ?
If the results are not as specified, replace the fuses as necessary.
3. CHECK V-RIBBED BELT
1.Check the belt for wear, cracks and other signs of damage.
If any defects are found, replace the V-ribbed belt.
HINT:
Replace the drive belt if any of the following defects are found: ?The belt is worn out and the wire is exposed.
?The cracks reach the wire in more than one place.
?The belt has pieces missing from the ribs.
2.Check that the belt fits properly into the ribbed grooves.
HINT:
With your hand, confirm that the belt has not slipped out of the grooves on the
bottom of the pulley.
4. VISUALLY CHECK GENERATOR WIRING
1.Check that the wiring is in good condition.
5. LISTEN FOR ABNORMAL NOISE FROM GENERATOR
1.Check that the generator does not emit any abnormal noise while the engine is
running.
6. CHECK CHARGE WARNING LIGHT CIRCUIT
1.Turn the ignition switch on (IG). Check that the charge warning light turns on.
2.Start the engine and check that the light turns off. If the light does not operate as
specified, troubleshoot the charge warning light circuit.
7. CHECK CHARGING CIRCUIT WITHOUT LOAD
1.Connect a voltmeter and an ammeter to the charging circuit as follows.
HINT:
If a battery/generator tester is available, connect the tester to the charging circuit in accordance with the manufacturer's instructions.
1.Disconnect the wire from terminal B of the generator and connect it to the
negative (-) lead of the ammeter.
2.Connect the ammeter positive (+) lead to terminal B of the generator.
3.Connect the voltmeter positive (+) lead to positive (+) terminal of the
battery.
4.Ground the voltmeter negative (-) lead.
2.Check the charging circuit.
1.Keep the engine speed at 2000 rpm and check the reading on the ammeter
and voltmeter.
Standard amperage:
10 A or less
Standard voltage:
13.2 to 14.8 V
If the result is not as specified, replace the generator.
HINT:
If the battery is not fully charged, the ammeter reading will sometimes be more
than the standard amperage.
8. CHECK CHARGING CIRCUIT WITH LOAD
1.With the engine running at 2,000 rpm, turn on the high beam headlights and turn
the heater blower switch to the HI position.
2.Check the reading on the ammeter.
Standard amperage:
30 A or more
If the ammeter reading is less than the standard amperage, replace the generator.
HINT:
If the battery is fully charged, the ammeter reading will sometimes be less than
the standard amperage. In this case, operate the wiper motor and the window
defogger to increase the load and then check the charging circuit again.
