Note:
- - Adjust the tester with the tuning knob while observing the signal.
- - Observations are carried out at the base engine speed.
Examples of abnormal waveforms
Note:
- − Identification of deviations from the normal form of the output voltage signal of the generator is simplified with a large output current of the generator (voltage regulator does not work; for example, you can observe the waveform of the output voltage when the headlights are on).
- Check if the battery charge indicator is on or off. Also check the entire charging system.
Note: At this time, the battery charging indicator is on
- Output voltage curve "IN" generator can change in waves, as shown in the figure. This voltage waveform occurs when the voltage regulator adjusts the generator output voltage according to the change in the generator electrical load, this is normal when the generator is running.
