Cougar Common Section 6 - 51
JOYSTICK TROUBLESHOOTING
Boom operation not responding to joystick movement.
Isolate hydraulic vs. electronic symptom.
Turn off electronic master switch (preventing electronic actuator on valve from attempting
to hold spool in neutral position). With tractor engine running, operate the valve section
with the manual handle. If function operates normally, continue with electronic inspection.
If function does not operate normally, continue with hydraulic inspection.
Electronic inspection.
Connect a voltmeter to the cable connector of the valve section that is not
operating. This will allow you to measure supply and signal voltage when the
joystick is operated.
Main, Secondary, and Swivel Valves – signal voltage should be 50% of supply
voltage with joystick in Neutral position, up to 75% of supply voltage in B
direction, down to 25% of supply voltage in A direction. Signal voltage should
change smoothly with lever movement.
Pin #1 – Supply Voltage
Pin #2 – Signal Voltage
Pin #gnd – ground
Deck Roll Valve or Float Valve – signal voltage should be 50% of supply
voltage with joystick in Neutral position, up to 65% of supply voltage in B
direction, down to 35% of supply voltage in A direction. Signal voltage should
change smoothly with lever movement. Signal voltage should be
approximately 75% of supply voltage when float switch is operated.
Pin #1 – Supply Voltage
Pin #2 – Signal Voltage
Pin #gnd – ground
Shield Valve or On/Off Valve – Voltage on pin #1 should be equal to supply
voltage when switch is operated in A direction. Voltage on pin #2 should be
equal to supply voltage when switch is operated in B direction.
Pin #1 – Signal Voltage
Pin #2 – Signal Voltage
Pin #gnd – ground
If none of the valve will operate with electrical signal, verify that there is oil
pressure at the valve inlet. Electrical Valves must have pilot supply oil to
move the spools.
Possible electronic problems.
Open circuit (broken wire, bad connection or loose connection in switch box).
Shorted to positive, ground, or other.
Incorrect voltage signal from joystick.
