Bench Testing: Rotor
WARNING: This page does not describe the selected car, but rather 16 other vehicles, including the 2001 Toyota Tundra, 2001 Toyota Tacoma, 2001 Toyota Sienna, 2001 Toyota Sequoia, and 2001 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
- Check rotor for open field windings by using an ohmmeter across slip rings. Rotor resistance should be within specification. See ROTOR RESISTANCE SPECIFICATIONS table.
- Check rotor for shorts to ground by connecting ohmmeter between slip ring and rotor shaft. Ohmmeter should indicate no continuity. Check slip rings for wear or pitting. Standard slip ring diameter is .559-.567" (14.2-14.4 mm). Turn slip rings on lathe if necessary. Minimum slip ring diameter is .504" (12.8 mm).
