Stator Drive End Frame
1. Using an ohmmeter (Figure 11-22, (1)) check
the continuity of the stator drive end frame
circuit. The stator circuit should have electrical
continuity between the coil leads. If continuity is
not measured, replace the drive end frame
assembly.

2. Using an ohmmeter (Figure 11-23, (1)) check
the stator for shorts to ground. The stator circuit
when measured between the coil leads and
drive end frame should have no continuity. If
continuity is measured, replace the drive end
frame assembly.

Brushes
1. Check the exposed brush length using calipers
(Figure 11-24). If the measured length is below
the specified minimum, replace the brush
holder.
Brush length:
• Brush Length (Standard) 10.5 mm (0.413 in.)
(1)
• Brush Length (Minimum) 1.5 mm (0.059 in.)
