POSSIBLE CAUSE
Hydraulic oil is too cold.
Low oil level.
Wrong oil.
Tractor PTO speed too low.
Clogged suction strainer.
Plugged pressure fi lter.
Plugged suction strainer.
One or both clutches dragging.
Prolonged inching.
Low oil level.
Control lever off-center at startup.
Control module not powered.
Control lever 24 VDC - 5 VDC
converter malfunction.
Activation switch off.
Control module fault.
Coil open or shorted.
PTO stalled (0 RPM).
Worn friction discs and separator
plates.
for Electronic Control Module. The charts list the most
common troubles that may be encountered. A possible
cause and recommended corrective action are listed to
restore the winch to normal operating condition.
CORRECTION
Put the control lever in the BRAKE-OFF position.
Run the engine at 1000 RPM to warm the oil before
operating the winch.
Add hydraulic oil to the correct level.
Drain oil and replace with correct grade. Refer to
Figure 1-12, for the
Recommended
Increase tractor engine speed to at least 1000 RPM
for good performance.
Check and clean or replace suction strainer.
Replace fi lter.
Check suction strainer, clean or replace.
Check by placing control lever in BRAKE-OFF. Nor-
mally drum will rotate slowly in either direction. If the
reverse clutch is dragging, the drum will rotate in the
LINE-OUT direction. If forward clutch is dragging the
drum will rotate in the LINE-IN direction, and it will
take more than 100 lbs of line pull to prevent drum
rotation.
Avoid continuous operation in the inching zone.
Add oil.
Return control lever to neutral position and attempt
function again.
Check fuse & replace if necessary.
Replace converter if the red & green LEDs are not lit.
Check status indicator on module. Red LED should
not be illuminated. If it is, consult dealer.
1. Check module output LEDs. Flashing LED indi-
cates open or shorted circuit.
2. Check wiring harness continuity.
3. Replace faulty coil.
NOTE: A working coil will have 15 to 50Ω
resistance and will be magnetized when ener-
gized.
Increase tractor RPM.
Replace the friction discs and separator plates if too
thin, scored or distorted. Refer to Section 4.
