Alternator: Testing and Inspection
Alternator Components Tests and Inspections
Rectifier Test
NOTE: The diodes are designed to allow current to pass in one direction while blocking it in the opposite direction. Since the alternator rectifier is
made up of eight diodes (four pairs), each diode must be tested for continuity in both directions with an ohmmeter that has diode checking capability; a
total of 16 checks.
1. Check for continuity in each direction, between the B and P, and between the E (ground) and P terminals of each diode pair. All diodes should
have continuity in only one direction.
2. If any of the eight diodes fails, replace the rectifier assembly. (Diodes are not available separately.)
Alternator Brush Inspection
1. Remove the end cover, then take out the brush holder by removing its two screws.
