Refer to joystick test procedure in section 5.
Check continuity. Replace if defective.
Check pin #5 for 12 volts. If no voltage present with
foot on footswitch check section 5 for OCM pin
voltage reference.
Check pin #10 for minimum 3.5 volts. If no voltage
present with foot on footswitch check section 5 for
OCM pin voltage reference.
Check continuity. Replace if defective.
Check for continuity between pins #15 on cable A.
Check for loose or corroded connections on cable
connectors. Replace if wire is defective.
Check continuity. Replace if defective.
Check continuity. Replace if defective.
Check continuity. Replace if defective.

Check continuity through switch while activating
the function between wires #38B and #38A.
Check continuity. Replace if defective.
Check voltage while operating telescope in. Voltage
should be between 4.75 and 5.25 volts. Refer to
