Larry,

Verification that the vessel steers properly by hand is an indication that any check valves within the vessel's steering system are functioning properly and would not be responsible for the reported symptom. It's certainly possible to place a voltmeter across the course computer's motor terminals (while leaving the motor leads attached) to view the voltage output. Autopilot drive units feature reversing DC motors. The voltage output is not variable. For 12VDC drive units, the voltage measured voltage at the course computer's terminals should be +12VDC when steering is commanded on one direction and -12VDC when steering is commanded in the opposite direction. As you have indicated that you can hear the pump running when commanded in either direction, the course computer would appear to be functioning properly.
