(78), if necessary.
TESTING
1.
Using 110 volt test lamp or ohmmeter, test stator
(72, Figure 4-11) for ground. Connect one test
wire to stator (72) frame and the other test wire
to each of three stator (72) wires. Replace stator
(72) if lamp lights or meter reading is low.
2.
Using 110 volt test lamp or ohmmeter, test stator
(72) for opens. Perform at least three tests,
switching test wires between any two of the
stator (72) wires. Replace stator (72) if lamp
does not light or meter reading is high.
3.
Using test lamp or ohmmeter, test field coil (75,
Figure 4-12) for ground. Connect one test wire to
field coil (75) housing and the other to each of
the field coil (75) wires. Replace field coil (75) if
lamp lights or ohmmeter reading is low.
4.
Using test lamp or ohmmeter, test field coil (75)
for opens. Connect both test wires to both field
coil (75) wires. Replace field coil (75) if lamp
does not light or meter reading is high.
