Verify that 7-pin warning light connector is properly connected.

Check for cut or damaged wire to switch.

Check for dirty or loose 7-pin connector at back of tractor and front of implement.

Single Point Depth Control Machine -No power to wing wheel activator valves.

Ensure that switch is activated when outer wing is folded over 180°. If a click is heard when switch lever is activated completely, switch was not activated.

With machine in unfolded transport position, 7-pin connector connected and tractor running, activate switch lever completely. If outer wings drop, valves are activated correctly. If out wings remain unchanged, wheel retraction valves are not being energized.

Single Point Depth Control Machine -Wing wheel switch not activated.

Adjust switch arm closer to hinge.
