October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Bench Testing: Diode
- Adjust ohmmeter to the x1 scale. Remove rectifier assembly from alternator. Place ohmmeter probe on terminal bolt. Touch remaining probe on each of 3 stator lead terminals. Note ohmmeter reading. Reverse probes and repeat test.
- Diodes should show a reading of approximately 6 ohms in one direction, and infinite readings with probes reversed. Repeat test for remaining set of diodes using other terminal bolt. Replace rectifier assembly if readings are not within specification.
