Alternator: Testing and Inspection
Alternator Components
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 terminals.
-
E (ground) and P terminals.
All diodes should have continuity in only one direction.
2. If any of the 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.
2. Measure the length of the brushes with a vernier caliper.
3. If the brushes are less than the service limit, replace the alternator brush assembly.
