Bench Testing: Rectifier: 80A/105A
WARNING: This page is about a different car, the 2003 Suzuki XL-7, 2003 Suzuki Vitara, and 2003 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.
- Positive rectifier, see Fig 1
- Using an ohmmeter, connect one tester probe to the "B" terminal (1) and the other to each rectifier terminal (2).
- Reverse the polarity of the tester probes and repeat step No. 1.
- Check that one shows continuity and the other shows no continuity. If there is continuity, replace rectifier.
- Negative rectifier
- Using an ohmmeter, connect one tester probe to each negative terminal (1) and the other to each rectifier terminal (2). See Fig 1.
- Reverse the polarity of the tester probes and repeat step No. 1.
- Check that one shows continuity and the other shows no continuity. If there is continuity, replace the rectifier.
