CHECK BATTERY CONDITION
Note
If the battery is weak or if the engine is difficult to start, perform the following procedures.
Check the battery for damage and deformation. If severe damage, deformation or leakage is found, replace the battery.
Check the electrolyte quantity of each cell.
For maintenance-free batteries:
If the electrolyte quantity is below the lower line, replace the battery.
If the electrolyte quantity 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.
Tech Tips
Before checking the battery voltage, turn off all the electrical systems (headlight, blower motor, rear defogger, etc.).
For non-maintenance-free batteries:
If the electrolyte quantity is below the lower line, add distilled water to each cell. Then, recharge the battery and check the electrolyte's specific gravity.
| Standard specific gravity |
|---|
| 1.25 to 1.29 at 20°C (68°F) |
If the electrolyte quantity 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.
Tech Tips
Before checking the battery voltage, turn off all the electrical systems (headlight, blower motor, rear defogger, etc.).
CHECK BATTERY TERMINAL AND FUSE
Check that the battery terminals are not loose or corroded.
If the terminals are corroded, clean the terminals.
Measure the resistance of the H-fuse and fuses.
| Standard resistance |
|---|
| Below 1 Ω |
If the results are not as specified, replace fuses as necessary.
CHECK DRIVE BELT
Убедитесь в отсутствии износа, трещин и других признаков повреждения.
В случае обнаружения любого из перечисленных ниже дефектов замените приводной ремень.
Ремень имеет трещины.
Ремень изношен до такой степени, что обнажились волокна
Отсутствуют элементы ребер ремня.
Убедитесь в том, что приводной ремень правильно располагается в углублениях шкива.
Tech Tips
Рукой проверьте, не выскользнул ли ремень из канавки нижней части шкива. Если ремень выскользнул из канавки шкива, замените приводной ремень. Правильно установите новый приводной ремень.
Убедитесь, что индикаторная метка натяжителя находится в диапазоне A, как показано на рисунке.
Если указатель не находится в диапазоне A, замените приводной ремень.
VISUALLY CHECK GENERATOR WIRING
Check that the wiring is in good condition.
LISTEN FOR ABNORMAL NOISES FROM GENERATOR
Check that the generator does not emit any abnormal noise while the engine is running.
CHECK CHARGE WARNING LIGHT CIRCUIT
Turn the ignition switch to ON. Check that the charge warning light turns on.
Start the engine and check that the light turns off.
If the light does not operate as specified, troubleshoot the charge warning light circuit.
CHECK CHARGING CIRCUIT WITHOUT LOAD
Connect a voltmeter and ammeter to the charging circuit as follows.
Tech Tips
If a battery/generator tester is available, connect the tester to the charging circuit according to the manufacturer's instructions.
Disconnect the wire from terminal B of the generator and connect it to the negative (-) lead of the ammeter.
Connect the ammeter's positive (+) lead to terminal B of the generator.
Connect the voltmeter's positive (+) lead to the positive (+) terminal of the battery.
Ground the voltmeter's negative (-) lead.
Check the charging circuit.
Keep the engine speed at 2000 rpm. 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.
Tech Tips
If the battery is not fully charged, the ammeter reading will sometimes be higher than the standard amperage.
CHECK CHARGING CIRCUIT WITH LOAD
With the engine running at 2000 rpm, turn on the high beam headlights and turn the heater blower switch to the HI position.
Check the reading on the ammeter.
| Standard amperage |
|---|
| 30 A or higher |
If the ammeter reading is less than the standard amperage, replace the generator.
Tech Tips
If the battery is fully charged, the charging circuit may not operate and the ammeter reading may be less than the standard amperage. If this is case, add more electrical load (operate the wipers, rear window defogger, etc.) and check the reading on the ammeter again.
