Stator Test: Cs144
- Scribe end frames to facilitate reassembly. Remove through bolts and separate end frames. Remove stator lead attaching nuts and remove stator.
- With ohmmeter set to its highest range, check that coil is not grounded to stator core. See Fig 1. Ohmmeter should indicate infinite resistance. If ohmmeter does not indicate infinity, replace stator. Stator cannot be checked for opens or shorts with ohmmeter.NOTE: Manufacturer recommends installing new bearing at slip ring end whenever alternator is reassembled.
- To reassemble alternator, reverse disassembly procedure. Retain brushes with brush retaining pin during reassembly. See Figure. Remove retaining pin after tightening through bolts.
