<P> A growler is an electrical device used for testing insulation of a motor for shorted coils . A growler consists of a coil of wire wrapped around an iron core and connected to a source of AC current . When placed on the armature or stator core of a motor the growler acts as the primary of a transformer and the armature coils act as the secondary . A `` feeler '' , a thin strip of steel ( hacksaw blade ) can be used as the short detector . </P>
