Starting System & Charging System (2.0L): Generator: Inspection: Diode
CAUTION:
There is the possibility of damaging the diodes if a mega-tester (used to measure high voltages) or a similar measuring instrument is used. Never use a mega tester or equivalent for this test.
- Check for continuity between the diode lead and terminal E or B. If continuity is not as shown in the table, replace the rectifier.
