All voltages given are with the SCM controller at maximum % adjustable settings.
All voltages should be tested with the key on and the foot switch depressed.
All tests should be performed with the platform over the drive axle, the boom fully stowed, and on flat level surface.
Pin 1 - 12 volt input from wire 4.
Test between pin 1 and 02 wire.
Pin 2 - 12 volt input from wire 4.
Test between pin 2 and 02 wire.
Pin 3 - 8 volt output from wire L to boom speed controller.
7.5 volts= speed controller in circuit.
Test between pin 3 and 02 wire.
Pin 4 - 12 Volt output on wire 30B to motor controller. Riser active signal. Gravity down.
Test between pin 4 and 02 wire.
Pin 5 - 12 volt output on wire 35 to jib up valve 4H-35.
Test between pin 5 and 02 wire while operating jib up.
Pin 6 - 12 volt output on wire 40B to platform level switch S12 (no output if operating another boom function).
Test between pin 6 and 02 wire.
Pin 7 - 12 volt output on wire 34 to jib down valve 4H-34.
Test between pin 7 and 02 wire while operating jib down.
Pin 8 - Boom down selected. Proportional output on wire 13 to boom down valve 4H-13.
0 volts to 11.1 volts depending on position of joystick. Threshold= 5.5 volt.
Test between pin 8 and 02 wire while operating boom down.
Pin 9 - Not used.
Pin 10 - Riser up selected. Proportional output on wire 31 to riser up valve 4H-31.
0 volts to 11.2 volts depending on position of joystick. Threshold= 4.5 volts.
Test between pin 10 and 02 wire while operating boom down.
