2128 The Left Stabilizer joystick is
not centered or one of the
joystick directional switches
is closed during system
startup. N Center joystick and normal operation
should resume. If not, check that the
command is 0% and the neutral switch
state is In-Neutral under Diagnostics/Mini
Joystick/Left Stabilizer Joystick on the
Analyzer when the joystick is centered. A
command = -100% and signal voltage =
0.0V indicates that the Joystick Power or
Signal wire has an open circuit. A
command = 100% and signal voltage >
4.75V indicates the Joystick Ground wire
has an open circuit. If the Neutral state
always indicates Neutral, then either the
directional switch or the Joystick Switch
Power wire has an open circuit.
If neutral voltage is near 2.4V or 2.5V
when centered, check that the joystick
voltage is still within the allowed deadband
detailed in the Personalities section. If
outside the deadband, adjust the
Personality setting for the Deadband.
If not, swap connector between Left
Stablilizer joystick and an adjacent Mini
Joystick to determine whether the Left
Stablilizer joystick is faulty. If the joystick is
fine, focus troubleshooting efforts on the
connector and wiring. If this is fine and the
Joystick Interface Module is suspected to
be faulty, verify by temporarily
interchanging wiring on the Joystick
Interface Module between joysticks for
troubleshooting purposes.
