E The measurement on the Neutral Test Point should be 12 or 24 VDC, depending on the
Solenoid’s rating and the LED adjacent to the socket should be illuminated.
F Move the Control Head lever to the Ahead Detent position. The voltage should drop to 0
VDC in CruiseCommand systems and remain at 12 or 24 VDC in ClearCommand systems. The
adjacent LED should go out in CruiseCommand systems and stay on in ClearCommand
systems.
2.2.2 Ahead Solenoid Testing
A Ensure power is removed from both the Processor and the Clutch Power Supply.
B Disconnect the Clutch Harness from the number 3 Processor connector/pigtail.
C Insert the Break-out Box between the number 3 Processor connector/pigtail and the Clutch
Harness as shown in Figure MM13927-10: Clutch Connections Ahead Solenoid.

D Set up the Multimeter to measure DC Volts and plug the black lead into the Break-out Box
socket labeled “CLUTCH -” and the red lead into the socket labeled “AHEAD”.
E Turn power ‘On’ to the Processor and take command at any Remote Station with the lever in
the Neutral/Idle position.
F The measurement should be 0 VDC and the adjacent LED should not be lit.
G Position the Control Head lever into the Ahead detent. The measurement should be 12 or 24
VDC depending on the Ahead Solenoid’s rating. The LED adjacent to the Ahead plug on the
Break-out Box should be lit.
H Return the Control Head lever to the Neutral/Idle position.
2.2.3 Astern Solenoid Testing
A Ensure power is removed from both the Processor and the Clutch Supply Power.
B Disconnect the Clutch Harness from the number 3 Processor connector/pigtail.
C Insert the Break-out Box between the number 3 Processor connector/pigtail and the Clutch
Harness as shown in Figure MM13927-11: Clutch Connections Astern Solenoid.
D Set up the Multimeter to measure DC Volts and plug the black lead into the Break-out Box
socket labeled “CLUTCH -” and the red lead into the socket labeled “ASTERN”.
E Turn power ‘On’ to the Processor and take command at any Remote Station with the Control
Head lever in the Neutral/Idle position.
