Pin 23 - Reverse drive selected. Proportional output on wire 15 to reverse drive valve 3H-15.
0 volts to 7.5 volts depending on joystick position. Threshold= 1.5 volts. Test between pin 23 and 02
wire while operating reverse drive.
Pin 24 - Battery negative. Wire 02.
Pin 25 - Battery negative. Wire 02.
Pin 26 - Battery negative. Wire 02.
Pin 27 - Accelerator input. Wire D from drive joystick controller.
Neutral position= 4.2 volts to 4.8 volts. Forward function= 4.9 volts to 8.5 volts. Reverse function= 4.1
volts to .5 volts. Test between pin 27 and 02 wire.
Pin 28 - Turret rotate input. Wire X from boom joystick controller.
Neutral position= 4.2 volts to 4.8 volts. Rotate right function= 4.9 volts to 8.5 volts. Rotate left
function= 4.1 volts to .5 volts. Test between pin 28 and 02 wire.
Pin 29 - Boom elevation input. Wire Y from boom joystick controller.
Neutral position= 4.2 volts to 4.8 volts. Boom up function= 4.9 volts to 8.5 volts. Boom down function=
4.1 volts to .5 volts. Test between pin 29 and 02 wire.
Pin 30 - Accelerator input. Signal wire (green wire) from boom speed controller.
Proportional voltage. .5 volts= slow speed up to 7.5 volts= fast speed.
Test between pin 30 and 02 wire while operating telescope in/out, jib up/down or basket rotate.
Pin 31 - 12 volt input from wire 59. From LS2 boom elevation limit switch and LS3 telescope limit switch.
12 volts= full speed. 0 volts= creep speed (one or more limit switches open). Test between pin 31 and
02 wire.
Pin 32 - Telescope selected. Input from wire 38A.
Neutral position= 3.58 volts.
Telescope in function= 4.83 volts.
Telescope out function= 2.41 volts.
Test between pin 32 and 02 wire.
Pin 33 - Jib function enable. 12 volt input from wire 34A.
Test between pin 33 and 02 wire.
Pin 34 - Forward drive selected. Proportional output on wire 16 to forward drive valve 3H-16.
0 volts to 7.5 volts depending on joystick position. Threshold= 1.5 volts. Test between pin 34 and 02
wire while operating forward drive.
Pin 35 - Turret rotate right selected. Proportional output on wire 33 to turret rotate right valve 4H-33.
0 volts to 5 volts depending on position of joystick. Threshold= .5 volts. Test between pin 10 and 02
wire while operating turret rotate right.
