Honda Fit: Rectifier Test

18. Check for continuity in each direction, between the B terminal and P terminals, and between the E terminal and P terminals of each diode pair. All diodes should have continuity in only one direction. Because the rectifier diodes are designed to allow current to pass in one direction, and the rectifier is made up of six diodes (six pairs), you must test each diode in both directions for continuity with an ohmmeter that has diode checking capability: a total of 24 checks:

    • If any diode failed, replace the rectifier assembly. (Diodes are not available separately.)

    • If all the diodes are OK, go to step 19.
