ABNORMAL WAVE-FORMS EXAMPLES
NOTE
1. The size of the wave-form patterns differs largely depending on the adjustment of the variable knob
on the analyzer.
2. Identification of abnormal wave-forms is easier when there is a large output current (regulator is not
operating). (Wave-forms can be observed when the headlights are illuminated.)
3. Check the conditions of the charge light (illuminated/not illuminated) also, and carry out a total check.
