Step B:
Press the left-side button on the switch labeled “DOWN”. The starboard actuator
should extend and the left-side indicator lights should track.
Press the right-side button on the switch labeled “UP”. The port actuator should
extend and the right-side indicator lights should track.
• If fault reading is present at the opposite side of the key pad, the actuator (or its
connections) may be defective. Proceed to Step 4.
• If fault reading is present at the same side of the key pad, the control box may be
defective. Call Lenco Marine for

Step 4: If fault continues, disconnect the Deutsch Connectors and remove the
orange wedge.
Step 5: Remove the wire leads from the connector by depressing the small
latches inside the connector housing and pulling on the wire leads.
Step 6: Once the wires are removed from the housing, touch the white wire
leads to a Positive (+) 12V Battery Terminal and the black wire leads
to a Negative (-) 12V Battery Terminal. The actuator should extend
while connected to the battery. Reverse the polarity of the wire leads
to the battery terminals and the actuator should retract.
If the actuator does not extend and retract, replace the actuator.
If the actuator extends and retracts properly, re-assemble the
connector taking care to properly seat the wire leads into the
connector housing. Proceed to Step 7.
Step 7: Attach the port and starboard connectors to the system. If the fault reading continues,
