WARNING: This page is about a different car, the 2001 Lexus RX 300, 2001 Lexus LS 430, 2001 Lexus IS 300, and 2001 Lexus GS 430. However, it is still accessible from the selected car via links, so may be relevant.
- Place diode (rectifier) assembly on bench. Connect ohmmeter positive lead to positive (+) terminal and negative lead to each rectifier terminal. See Fig 1. Reverse ohmmeter leads and check again. Continuity should exist in only one direction.
- Connect ohmmeter positive lead to each rectifier terminal and negative lead to each negative (-) terminal. Reverse ohmmeter leads and check again. Continuity should exist in only one direction. If continuity is not as specified, replace diode assembly.
