Solenoid mounting screw removal
may require the use of an impact type
driver.
(2) Install Solenoid. Refer to figure 4-22A.
Support new solenoid (3) and original spacer(s), en-
gage solenoid plunger on Iever(yoke), secure using
new screws (1).
g. Install Starter. Refer to figure 418. Slide
starter into opening in flywheel housing (17). Make
certain starter lies flat against housing. Attach starter
to housing with screws (13) and Iockwashers (14). For
Style I Starter, swing support bracket(12) into position
at back of the starter, and attach with screw (9), nut (7)
and Iockwasher (8). Tighten screw (10) and lock
washer (11) securing support bracket (12) to engine
block. Replace tagged leads per diagram, figure 418.
Remove tags.
427. BATTERY CHARGING ALTERNATOR.
a. Battery Alternator Stator (see figure 423).
On ASK equipped generators, remove ASK cover as-
sembly (para 53).
(1) Remove blower housing (see paragraph
417).
( 2 ) I n s p e c t . T h e p r e s e n c e o f t h e b l o w er
wheel limits inspection of the battery alternator to in-
specting that two leads (1) from stator (2) are free of
damage and are not rubbing against blower wheel and
are securely connected to terminal block (3) located on
engine back plate (4).
Avoid contact with blower wheel while
testing battery alternator voltage.
( 3 ) T e s t.
Do not operate unit more than 3 min-
utes with blower housing removed.
Rotate Stator so wires come off the
top. Place clamp on top of oil pump.
Run wire over top of oil pump.
(a) Tag and disconnect stator lead (1) frcm
stator at terminal block (3) Check between two stator
leads for approximately 0.6 ohms continuity. If open cr
shorted, notify higher level of maintenance. Check for
continuity between each lead and ground. If continuity
is found, notify higher level of maintenance.
(b) With the stator leads (1) disconnected,
check voltage across two leads (1) from stator. Voltage
should be in a range of 3035 volts AC with the engine
operating normally at 1800 RPM. If voltage is less than
30 volts AC, stator on magnets in rotor may be defec-
tive. Refer to higher level of maintenance for
replacement of stator or rotor. Reconnect stator leads
(1).
Avoid operation of Generator Set for
more than 3 minutes with engine
blower housing removed, as engine
will overheat.
b. Battery Charging Regulator/Rectifier Assem-
bly (see figure 4-23).
(1) Inspect. Inspect regulator/rectifier as-
sembly (5) for physical damage. Check that leads from
assembly to terminal block (3) are not damaged or
frayed. Check that assembly Is securely mounted to
engine back plate (4).
( 2 ) T e s t.
(a) Test stator as given In paragraph
427A above to see that it is operating correctly.
(b) Remove fuse (9, figure 4-23) and con-
nect a 10 amp ammeter across the fuse holder
terminals as shown in figure 424. With engine operat-
ing normally at 1800 RPM, charge rate shou!d be no
less than 6.5 amps when loaded by a discharged bat-
tery. Charge rate should taper-off as battery becomes
charged.
