Operational Troubleshooting
This section describes possible problems and
provides basic solutions to problems which may be
encountered during machine operation. This section is
only a guide: not all possible problems and corrections
are addressed. If a problem is not covered, or if the
problem is not corrected by the action described in
this section, refer the problem to Unit Maintenance for
resolution.

Problem 1: Starter Fails to Crank When Start
Switch Is Held in START Position
Probable Cause(s):
• Transmission not in NEUTRAL
• Main disconnect switch OFF
• Circuit breaker(s) tripped
• Batteries not providing voltage
1. Transmission not in NEUTRAL:
a. Inspect the position of the transmission control
lever. If the transmission control lever is in
NEUTRAL, go to Step 2. If the transmission
control lever is not in NEUTRAL, go to Step b.
b. Move the transmission control lever to
NEUTRAL, and attempt to start the engine
again. If the engine does not crank, go to Step
2.
2. Main disconnect switch OFF:
a. While holding the start switch in the START
position, observe the tension fail indicator, the
low brake pressure indicator, the engine oil
pressure indicator, and the hydraulic oil
temperature indicator. If any of these lamps
illuminates, go to Step 3. If none of these lamps
illuminates, go to Step b.
b. Check the position of the main disconnect
switch. If the main disconnect switch is ON, go
to Step 3. If the main disconnect switch is OFF,
go to Step c.
c. Move the main disconnect switch to ON, and
attempt to start the engine again. If the engine
will not crank, go to Step 3.
3. Circuit breaker(s) tripped:
Reset the following circuit breakers: main, start
switch, ECM, and EPTC II. Attempt to start the
engine again. If the engine will not crank, go to
Step 4.
