Test Armature for Shorted Winding: When the armature is rotated in the growler with steel strip (hacksaw blade) held above it, the strip will vibrate over that area of the armature which has short circuitReplace armature if so1

Check the dynamic brake winding for open circuit by placing one test probe on the positive brush and the other probe on the negative brushIf growler lamp does not turn on, the winding circuit is open-circuit and the yoke has to be repaired or replaced
Test the Armature for Open Circuit: Use growler test probesPlace one test probe on commutator bar and the other test probe on the neighboring barRepeat this operation for all bars, moving one test probe at timeIf the growler lamp does not turn on, the armature circuit between these bars is openedThe armature should be replaced or repaired; open circuits most often occur at the commutator riser where coils are soldered(Burnt commutator bars are usually an indication of an open-circuit armature coil)
