1. INSPECT FIELD COIL FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between
the lead wire and field coil brush lead.
If there is no continuity, replace the field frame.

Brushes
INSPECT BRUSH LENGTH
Using a vernier caliper, measure the brush length.
Standard length:
15.5 mm (0.610 in.)
Minimum length:
10.0 mm (0.394 in.)
If the length is less than minimum, replace the brush holder
and field frame.

Brush Springs
INSPECT BRUSH SPRING LOAD
Take the pull scale reading the instant the brush spring sepa-
rates from the brush.
Spring installed load:
18–24 N (1.79–2.41 kgf, 3.9–5.3 lbf)
If the installed load is not within specification, replace the
brush springs.
