b Test Procedure
1. Turn power on to both Port and Starboard Processors. Take command at a Control Head.
2. Move the Port and Starboard Control Head levers to approximately ½ Ahead.
3. Locate the green wire coming from the Port Control Head in command, connecting to pin 6
of the respective terminal block on the ClearCommand 9000 Series circuit board.
Disconnect it from the ClearCommand 9000 Series circuit board.
c The Port Processor will shift to Neutral and throttle will go to Idle.
d The Port Control Head will give an alarm tone indicating a faulty potentiometer.
1. Move the Port and Starboard Control Head levers back to Neutral. Reconnect the green
wire.
2. Repeat for Starboard side.
Failure: Power failure to ClearCommand 9000 Series
A power failure to the ClearCommand 9000 Series circuit board will have the same results as a failed
microprocessor
a Results
1. Throttle signal to Idle and shift to Neutral.
2. LED at Control Heads will not be lit.
3. Opposite engine still under power has full control.
b Test Procedure.
1. Turn power on to both Port and Starboard Processors. Take command at a Control Head.
2. Move the Port and Starboard Control Head levers to approximately ½ Ahead.
3. Turn power off to the Port side only.
• Port side will go to Neutral Idle.
• LED on the Port side of the Control Head in command will go off.
• The Port Control Head will no longer have command of the engine and gear.
• The Starboard Control Head will still have full command of the Starboard
engine and gear.
4. Turn power on to the Port Processor. Take command of the Port side.
5. The Port Control Head will operate as usual-(Non-volatile memory)
6. Repeat test for Starboard Processor.
