Stator Ground Test

1998 Mercury Villager GS, Van CargoSECTION Stator Ground Test
  1. Inspect stator laminations closely for signs of overheating. A burnt spot usually indicates shorted stator windings. Remove stator from generator. Set ohmmeter to X1000 scale. Connect one ohmmeter probe to one stator lead. Connect other probe to stator core. Ohmmeter should indicate infinite ohms.
  2. If meter indicates any continuity, stator winding is shorted to core and must be replaced. Repeat test for each stator lead. DO NOT  touch probes or stator leads, or an incorrect reading will result.
