Step 2.
Check transmission shift control, shift control cable, or shift control linkage
for damage, looseness, and proper adjustment.
Replace any damaged transmission shift control, shift control
cable, or shift control linkage (page 4-335). If transmission shift
cable and linkage is out of adjustment, readjust cable and
linkage (page 4-342).
Step 3.
If problem still exists, notify direct support maintenance.
POWER TAKE-OFF (PTO) CIRCUITS (ALL EXCEPT M915A2)
1. POWER TAKE-OFF (PTO) DOES NOT ENGAGE.
Step 1.
Check reservoir heater/power take-off 15A fuse.
If defective, replace 15A fuse (page 4-204).
Step 2.
Remove reservoir heater/power take-off 15A fuse. Check for +12 VDC at
fuse connector from lead 18.
If +12 VDC is present, go to step 3. If no voltage is present,
repair lead 18 (page 3-2).
Step 3.
Disconnect lead 200D from power take-off switch on dash. Check for +12
VDC at lead 200D.
If +12 VDC is present, go to step 4. If no voltage is present,
repair lead 200D (page 3-2).
Step 4.
Disconnect lead 200D and lead 200E from power take-off switch on dash.
Check for continuity between contacts at power take-off switch with switch
closed.
If continuity is indicated, go to step 5. If no continuity is
indicated, replace power take-off switch on dash (page 4-182).
Step 5.
Disconnect lead 200E from power take-off solenoid valve. Check for +12 VDC
at lead 200E with power take-off switch on dash closed.
If +12 VDC is present, go to step 6. If no voltage is present,
repair lead 200E (page 3-2).
Step 6.
Disconnect lead 200E from power take-off solenoid valve. Disconnect power
take-off solenoid ground lead from ground. Check for continuity between
power take-off 200E connector and ground lead.
If continuity is indicated, repair ground lead to ground. If no
continuity is indicated, replace power take-off solenoid valve
(page 4-768). If power take-off still will not engage, notify direct
support maintenance.
