7. 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.
8. INSPECT FIELD COIL FOR GROUND
Using an ohmmeter, check that there is no continuity between
the field coil end and field frame.
If there is continuity, repair or replace the field frame.
9. 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.
10. INSPECT BRUSH SPRING LOAD
Take the pull scale reading the instant the brush spring sepa-
rates from the brush.
Standard spring installed load:
17.6 - 23.5 N (1.8 - 2.4 kgf, 3.9 - 5.3 lbf)
Minimum spring installed load: 11.8 N (1.2 kgf, 2.6 lbf)
If the installed load is less than minimum, replace the brush
springs.
