The center support is located at the center of the
housing and provides a means of lifting the genera-
tor set by use of a clevis located on each side of
the top of the center support. The start aid as-
sembly mounted on the center support, is used as
an aid in starting the engine at temperatures below
40° F. This system is controlled by the ENGINE
PRIMER switch on the control cubicle panel when
the engine is being cranked aml the START-RUN-
STOP switch is in the START position. Each time
the ENGINE PRIMER switch is momentarily actu-
ated, under these conditions, one metered shot of
ether is injected into the engine air intake system.
This section also contains information for main-
tenance of the electric fuel transfer pumps which
are utilized to transfer fuel from the main fuel
tank to the day tank.

(2) Crank the engine and momentarily actuate
and release the ENGINE PRIMER switch, while an ob-
server watches the solenoid valve (4) opening. If no
spray of ether is observed, perform step (3).
(3) Listen for audible evidence of solenoid
valve (4) operation while the ENGINE PRIMER
switch is repeatedly actuated.
(4) If solenoid valve (4), operation is veri-
fied in step (3), replace ether tank (8) as follows:
(~) Open bracket (7).
@) Unscrew ether tank (8) from solenoid
valve (4) and remove ether tank.

solenoid valve (4).
(5) If solenoid valve (4) operation was not
verified in step (3), disconnect solenoid connector
and check for 24 volts dc at the pins of its mating
connector each time the ENGINE PRIMER switch is
actuated with the engine cranked.
(6) If 24 volts dc is measured in step (5), re-
place the solenoid valve (4) as follows:
(~) Remove two screws (9) and nuts (10)
which secure the solenoid valve (4) to the frame-

open bracket (7) and remove the tank and attached
solenoid valve as an assembly.
(c) Remove adapter (3) and install in a
new solen~id valve.
(~) Install the new solenoid valve (4) with
adapter using two screws (9) and nuts (10). Do not
tighten screws (9) securely.
(g) Connect tube (1) to adapter (3) on
solenoid valve (4) and tighten the solenoid valve
mounting screws (9) securely.
(f) Screw a new ether tank (8) into the
solenoid ~itlve (4).
(g) Close bracket (7) to secure ether tank
