fully the proper connecttons. then proceed as
follows:
1. To check the stator and diodes, remove the three
nuts, the three regulator leads. the three stator
leads, the SIX diode leads, and the "R" terminal
lead from the three studs. During reassembly
place over each stud in this order the two diode
leads, the stator lead, the "R" terminal lead on
one stud only. the regulator lead, and the nut.
2. To check the field coil, disconnect the two field
coil leads from the regulator.
3. Later on, it may be necessary
to separate the
drive end frame assembly from
the rectifier end
frame assembly by removing the
shaft nut, wash-
er, pulley, fan. slinger and the
thru bolts from
the drive end
FIELD COIL CHECKS (Figure 7)
To check for grounds, connect a test lamp, or
an ohmmeter to one field coi1 lead and to the end
frame as illustrated. If the lamp lights, or if ohm-
