I recently bought a 2006 Malibu wakesetter 23 LSV knowing the power wedge didn’t work. I have a grey,green and white wire going from the control box to the switch. None of the 3 wires are carrying any power from the box to the switch. Just using a low voltage light bulb tester. Do I need a new control box? It was replaced in 2016 and surprised it would go bad again. Any help is appreciated

Check the inline fuse to the Lenco control box under the dash.

Sorry I’m new to this forum and didn’t see the comments. I don’t have any inline fuse. Only a breaker

I think some of the very first Lenco control boxes had a 30 amp breaker, but most have a 20 amp inline fuse holder on the red power wires that go to the box.

The Lenco box harness wires are:

1, red, 12v+ power in

2, red, 12v+ power in

3, white, power/ground out to actuator 1

4, black, power/ground out to actuator 1

5, white, power/ground out to actuator 2

6, black, power/ground out to actuator 2

7, black, ground

8, black, ground

9, blue, dash switch up top

10, green, dash switch common center

11, white, dash switch down bottom

12, purple, to speed/paddlewheel green wire

13, yellow, trim gauge

14, black, ground

If you have a newer control box, version 3 or newer number 6174005.2 to 6174005.5, there should be an additional orange wire connected to pin 15 and connected to the switched power/purple at the ignition key switch.  It is available from Malibu PN 6174015.

First make sure you have battery voltage at the red wires 1 and 2;  Ground at black wires 7, 8, and 14.

The dash switch common green wire center post should read ground and the other posts should be open when the switch is not pushed.  The blue wire up top post will read ground when the switch is pushed up and the white wire down bottom post will read ground when the switch is pushed down. 

The wedge has speed based controls so the speedo must read 0-9 MPH to deploy the wedge down and must read 1-9 MPH to stow the wedge up.  If the wedge is down it can be moved up or down in the lower drag positions from 0-25 MPH.  You may need to spin the paddle wheel by hand to simulate speed when diagnosing a wedge problem.

The white and black output wires to the actuators will read battery voltage on one wire and ground on the other when the actuators extend, then the wires will have the opposite reading when the actuators are retracted.
