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: Rotor
- Check rotor for open field windings by using an ohmmeter across slip rings. Rotor resistance should be 4.0-4.2 ohms for Tercel alternator without IC regulator and 2.8-3.0 ohms for all other models.
- Check rotor for shorts to ground by connecting ohmmeter between slip ring and rotor shaft. Ohmmeter should show no continuity. Check slip rings for wear or pitting. Turn rotor on lathe if necessary. Check bearing and replace if necessary.
