Place armature in growler and hold a thin steel blade parallel to the core and just above it. Slowly ro-
tate armature in growler. If blade vibrates and is attracted to core, replace armature.
Connect test lamp probes to armature and each commutator riser bar. If test lights come on, armature
is grounded and needs to be replaced.
Inspect end cap assembly for cracks, breaks in brush wires, and loose brush wire-mounting screws.
Measure brush length. If brushes are 1/8 in. (1/3 cm) or less in length, replace them.
