Troubleshooting Guide
The charging system troubleshooting guide is shown in the following steps.
- STEP 1.
Q: Is the battery in good condition? (Refer to BATTERY CHECK .)
YES: Go to Step 2.
NO: Charge or replace the battery.
- STEP 2.
Q: Is the generator drive belt in good condition? (Refer to DRIVE BELT (FOR GENERATOR, WATER PUMP AND POWER STEERING OIL PUMP) (CHECK CONDITION) .)
YES: Go to Step 3.
NO: Adjust the belt tension or replace the belt.
- STEP 3.
Does the generator malfunction light turn on brightly when the ignition switch is turned to the "ON" position?
YES: Go to Step 4.
NO:
- Check the ignition switch. (Refer to INSPECTION .)

- Check the generator. (Refer to INSPECTION .)
- Check the generator malfunction light-related circuits.
- STEP 4.
Q: Does the generator malfunction light go out after starting the engine?
YES: Go to Step 5.
NO: Check the generator (Refer to INSPECTION .)
- STEP 5.
Q: Is an oscilloscope available?
YES: Go to Step 6.
NO: Go to Step 7.
- STEP 6.
