Stator Windings Grounded Test
NOTE:
To perform the following test, disassembly of the alternator is required. The rectifier assembly must be disconnected from the stator prior to performing tests to either unit.
- Inspect stator laminations closely for signs of overheating. A burnt spot usually indicates shorted stator winding. Remove stator from alternator. Set ohmmeter on "x1000" scale. 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 must be replaced. Repeat test for each stator lead. DO NOT touch probes or stator leads, or an incorrect reading will result.
