Testing & Repair: Stator

  1. Place ohmmeter on lowest scale. Connect ohmmeter across stator leads. Resistance between leads should be .14-.15 ohms for 55-amp alternator and .09-.10 ohms for 65 through 90-amp alternators. If resistance is incorrect, stator has open or shorted windings and must be replaced.
  2. Place ohmmeter on x1000 scale. Connect ohmmeter between stator core and stator lead. No continuity should exist. If continuity exists, stator is grounded and must be replaced.
