7.16.3 Check if battery voltage is being sent to the load pin from the control

board. To do so, turn the ignition switch ON, connect the black lead of

a multimeter to a common ground, and back probe the #1 terminal of

the P2 connector with the red lead of the multimeter. The multimeter

should read battery voltage (approximately 12VDC).

• If no voltage is present, the control board has failed; replace it.

• If battery voltage is present, continue.

7.16.4 Check if feedback voltage is being sent from the load pin to the control

board. To do so, leave the black lead connected to the common

ground, back probe the #2 terminal of the P2 connector with the red

lead, and turn the ignition switch ON. With the right joystick in the

center (neutral) position, the multimeter should read 2.5±0.2 VDC.

• If 2.5±0.2 VDC is present, the system should be functioning. Any

problems are internal to the software of the control board. Con-

sult Wacker Service.

• If no voltage is present, the right load pin has failed; replace it.
