Connecting spool valves

If the drive has spool valves, connect them to the motor and solenoid terminals on the course computer as shown below. The course computer provides a negative ground for the spool valves even when it is switched off.

CAUTION:

Do NOT connect the solenoid return cables to boat’s negative ground, as this will bypass the current protection devices inside the course computer.
