CLASSIC II
SHUNT FIELD WINDING TEST (continued)
6. Using the volt/ohmmeter set on the low
scale (X1), measure the resistance
between the blue and the brown leads.
See Figure F.5. Normal resistance is
approximately 57 ohms.
7. Also measure the resistance from either
lead (blue or brown) to ground. Set the
volt/ohmmeter on the high scale (X100,000).
This resistance should be at least 500,000
ohms.
8. If the test does not meet the resistance
specifications, then check the harness plug
and inline connectors for loose connec-
tions or shorted leads.
9. If the plug and associated leads are okay,
then the shunt field coils may be faulty.
Replace.
10. If the test does meet the resistance specifi-
cations, then the shunt coils are okay.
11. Replace plug P10, making sure the leads
and plug are secure.
12. Close and latch the right side door.
