IMPORTANT
TESTING FUEL SOLENOID
Adjust cable as described in previous sec-
tion. This model solenoid will not engage until
engine is cranked. Disconnect shut-off ca-
ble from fuel shut-off lever and operate start
switch. After briefl y cranking the engine and
with the key switch in the run position, the
fuel solenoid should be engaged (pulled in). If
it does not engage, check for a blown in-line
fuse at the starter. If the fuse is not blown, test
the solenoid as follows.
Unplug the wires leading to the fuel solenoid.
Using an ohmmeter set on the X 1 OHM
scale, connect meter leads to solenoid wires.
Correct meter readings should be:
“Comm” wire to “Pull” wire - .25 ohms
“Comm” wire to “Hold” wire - 14 to 16
ohms
If you do not get these readings or one of the
circuits reads open, the solenoid is defective
and must be replaced.
ENGINE TROUBLESHOOTING
Should you experience trouble in starting the
engine, use the following guide to locate pos-
sible causes.
Engine will not crank:
•
Battery is discharged.
•
Blown starter fuse.
•
PTO switch is “ON”.
•
Steering levers are not out in neutral.
•
Steering lever switches are out of adjust-
ment (listen for the switch “click”).
•
A loose wire or connection.
Engine cranks, but will not start:
Determine if the fuel solenoid is stroking when
the key switch is turned to the start position. If
it is not, check for a blown fuse at the starter
(item 17, page 44). If the fuse is not blown,
check for voltage in the black wire at the fuel
solenoid plug while the engine is cranking. If
there is voltage to the solenoid while the en-
gine is cranking, go to solenoid testing in the
previous section.
If fuel shut-off solenoid is stroking but the en-
gine will not start, it is possible the fuel line has
become fi lled with air. The possible causes of
a fuel line fi lled with air are:
•
Running fuel tank empty before refueling.
•
Plugged fuel fi lter.
•
Loose or broken fuel line connection.
To bleed the air from the fuel lines follow the
procedure outlined. Refer to “Engine Manual”
for illustrations of the parts described.
•
Unplug the fuel shut-off solenoid (item 34
page 35).
•
Loosen air vent plugs on the fuel fi lter sev-
eral turns. Crank the engine until bubbles
do not come out any more. Tighten air
vent plugs.
•
Loosen air vent plug on top of the fuel injec-
tion pump. Crank the engine until bubbles
do not come out anymore. Tighten air vent
plug.
Cranking the engine for more than
15 seconds at a time can burn out
the fuel solenoid and can lead to
premature starter failure.
•
Connect the fuel shut-off solenoid.
•
If engine will not start after bleeding air
from the line, review trouble shooting sec-
tion of Engine Manual.
Engine dies when steering levers are en-
gaged:
•
If engine starts and runs but dies when
either steering lever is engaged, check the
following. Make sure the parking brake is
released. The steering levers cannot be
engaged with the parking brake on. With
the key switch “ON” and the seat switch
engaged, check for ground at the two yel-
low wires on the seat switch. If there is
ground at one wire but not the other, ei-
ther the seat switch is defective or it is not
being activated properly.
