Stator Coil Grounded Test
- Remove and disassemble alternator. This test determines if stator coil is properly insulated. Remove stator from alternator. Set ohmmeter in "x1000" range.
- Connect one ohmmeter probe to one stator lead and other probe to stator laminated core. Ohmmeter reading should be infinity.
- If meter needle moves, stator winding is shorted to core and stator must be replaced. Repeat test for each stator lead.
NOTE:
DO NOT touch metal probes of ohmmeter or stator leads during resistance test. Incorrect reading will result.
