6.
Use ohmmeter to test stator for windings continuity by
taking three readings between pairs of the three stator
wires (29). Replace if readings are not 0.15-0.25
ohms.
7.
Use ohmmeter to test stator for shorts to frame by
touching one wire to stator frame and touching the
other to each of three stator wires (29). Readings
should be very high. If not, replace stator.

8.
Use ohmmeter to test diode assembly (28) for minus
diode test. Connect one test lead to frame (9) and the
28
29
other test lead to each of the terminals (30) on the
diode assembly (28) where the three stator wires (29)
were disconnected. Then switch the test wires from
diode assembly (28) to frame. If one high and one low
reading are not obtained, replace diode assembly (28).
9.
Test diode assembly (28) for positive diode test by
performing test the same way as minus diode test,
except connect one wire to the (B+) terminal. Results
should be the same.
10.
Test diode assembly (28) for excitation diode test by
performing test the same way as minus diode test,
except connect one test wire to (D+) terminal.
