Trouble Shooting
- Is battery in good condition?
- If Yes, then go to next step.
- If No, then charge or replace battery.
- Is generator drive belt in good condition?
- If Yes, then go to next step.
- If No, then adjust belt tension or replace belt.
- Does the generator malfunction light come on when the ignition switch is turned on?
- If Yes, then go to next step.
- If No:
- Check the ignition switch.
- Check for burnt-out generator malfunction light.
- Check the generator.
- Check the generator malfunction light-related circuits.
- Does the generator malfunction light go out after starting the engine?
- If Yes, then go to next step.
- If No, check the generator.
- Is an oscilloscope available?
- If Yes, then go to next step.
- If No, then go to step 7
.
- Does the oscilloscope show a normal wave pattern?
- If Yes, then go to next step.
- If No, then check the generator.
- Turn the engine on and idle at 2500 RPM. Turn the headlights on with the High Beams on. Be sure that there is voltage between generator terminal B and the positive battery terminal of 0.5V or less. Check that the voltage between the negative battery terminal and generator body is 0.5V or less. Are the generator output line and ground line in good condition?
- If Yes, then go to next step.
- If No, check the generator output line and ground line.
- Is the output current normal?
- If Yes, then go to next step.
- If No, then check the generator.
- Is the regulated voltage normal?
- If Yes, then go to next step.
- If No, then check the generator.
- Is the voltage drop in the generator output line normal?
- If Yes, then generator is normal. Check other systems.
- If No, then check the output line.
