CONTACTOR DRIVER 
PERMANENTLY ON

The power modules line contac-
tor drive circuitry failed to de-
energize when requested. Drive, 
steer and lift up prevented.

Check continuity between contactor connector pin 1 and ground board
socket J1-19.

Check continuity between contactor connector pin 2 and power module
12 position connector terminal 8.

Replace power module.

331

BRAKE SHORT TO BAT-
TERY

The ground board detected 
voltage while the brake sole-
noid was commanded off.

Ensure ANALYZER -> MACHINE SETUP -> ELEV PROX is set to NOT
INSTALLED.

332

BRAKE OPEN CIRCUIT

The ground board did not 
detect current flow to the brake 
solenoid during normal opera-
tion.

Ensure ANALYZER -> MACHINE SETUP -> ELEV PROX is set to NOT
INSTALLED.

333

LIFT UP SHORT TO BAT-
TERY

The ground board detected 
voltage while the lift up sole-
noid was commanded off at 
power up.

Check for continuity through this circuit. The lift up solenoid resistance
should measure about 30 Ohms. The lift up solenoid is powered with 24V
from ground board J1-25, and its ground is to ground board J1-30, 37.

Inspect the wiring for physical damage.

Replace ground board.

334

LIFT UP OPEN CIRCUIT

The ground board did not 
detect current flow to the lift up 
solenoid during power up.

Check for continuity through this circuit. The lift up solenoid resistance
should measure about 30 Ohms. The lift up solenoid is powered with 24V
from ground board J1-25, and its ground is to ground board J1-30, 37.

Inspect the wiring for physical damage.

Replace ground board.

335

LIFT DN SHORT TO BAT-
TERY

The ground board detected 
voltage while the lift down sole-
noid was commanded off.

Check ANALYZER -> MACHINE SETUP ->  ELEV  PROX  is  set  to  NOT
INSTALLED

Check for continuity through this circuit. The lift down solenoid resistance
should measure about 20 Ohms. The lift down solenoid is powered
(PWM) by ground board J1-26, and its ground is to ground board J1-27.

Inspect the wiring for physical damage.

Replace ground board.

336

LIFT DN OPEN CIRCUIT

The ground board did not 
detect current flow to the lift 
down solenoid during normal 
operation.

Check for continuity through this circuit. The lift down solenoid resistance
should measure about 20 Ohms. The lift down solenoid is powered
(PWM) by ground board J1-26, and its ground is to ground board J1-27.

Inspect the wiring for physical damage.

Replace ground board.

337

STEER LEFT SHORT TO 
BATTERY

The ground board detected 
voltage while the steer left sole-
noid was commanded off at 
power up.

Check for continuity through this circuit. Steer left solenoid resistance
should measure about 30 Ohms. The steer left solenoid is powered with
24V from ground board J1-21, and its ground is to ground board J1-30,
37.

Inspect the wiring for physical damage.

Replace ground board.

338

STEER LEFT OPEN CIR-
CUIT

The ground board did not 
detect current flow to the steer 
left solenoid during normal 
operation.

Check for continuity through this circuit. Steer left solenoid resistance
should measure about 30 Ohms. The steer left solenoid is powered with
24V from ground board J1-21, and its ground is to ground board J1-30,
37.

Inspect the wiring for physical damage.

Replace ground board.
