Rotor Slip Ring

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2004 Acura 3.5RL, 2003 Acura 3.5RL, 2002 Acura 3.5RL, 2001 Acura 3.5RL, and 2000 Acura 3.5RL. However, it is still accessible from the selected car via links, so may be relevant.
  1. Check the resistance between the slip rings. There should be 2.9 ohms. If resistance meets the specification, go to next step. If resistance does not meet the specification, replace the alternator.
  2. Check that there is no continuity between the slip rings and the rotor or rotor shaft. See Fig 1.
  3. If the rotor fails either continuity check, replace the alternator.
