8-1 NO AC OUTPUT
8-1-1 CHECKING STATOR
(1) Remove control panel and disconnect stator wires at the connectors.
(2) Measure the resistance between terminals
on stator leads.
Refer to Table of Section 6-3 STATOR for
normal resistance.
If stator is faulty, replace it with a new one.
(3) Check the insulation resistance between
stator core and each stator lead using a
megger tester.
If insulation is bad, replace stator with a
new one.
8-1-2 CHECKING ROTOR
1) Field coil
Remove the brush holder and measure
resistance between the slip rings. Refer to
Section 6-4 ROTOR ASSEMBLY for normal
Resistance
NOTE : If the circuit tester is not sufficiently
accurate, it may not show the values
given and may give erroneous readings.
Erroneous reading will also occur when
there is a wide variation of resistance
among coil windings or when
measurement is performed at ambient
temperatures different from from 20°C
(68°F).
