Guidance System Trouble-Shooting

  1. If the power light is not on:
    1. Check the fuse on control box and replace if necessary.
    2. Check connections at box and and at power supply (need 12 V).
  2. If the hitch sensor light is not on:
    1. Check the main control cable for any pinches.
    2. Check the cable and box connections for broken pins.
  3. If the wand sensor light is not on:
    1. Check the wand control cable for pinches.
    2. Check the cable and box connections for broken pins.
  4. Switch the control box Manual/Automatic switch to Manual.
    1. If the manual light is not on, replace the Manual/Automatic switch.
    2. If the hitch will not move when turning the manul knob from left to right:
      1. If the left or right valve lights on hitch box do not come on -- call factory.
      2. The system is designed to allow oil to only flow in one direction. It may be necessary to reverse the direction of the hydraulic remote lever in the tractor.
      3. Turn off the main power switch. Warning! Hitch should move when performing next test. Stay clear of all moving parts! Push 1/4" Manual Override button on end of solenoid valve with a small punch. If hitch still does not move, check tractor hydraulics.
    3. If the hitch is moving backwards, turn off the main power switch while the hitch is moving. If the hitch stops:
      1. reverse the solenoid cables.
      2. If the hitch does not stop, check the solenoid. It is probably sticking.
    4. If the hitch moves back and forth, but does not center or does not travel equal distance:
      1. See the Hitch Calibration section of the owner's manual.
  5. Switch the control box Manual/Automatic switch back to Automatic.
    1. If the Automatic light is on:
      1. Make sure the mercury switch is properly attached.
      2. If the Automatic light will not come on regardless of how the mercury switch is tipped, check the wiring and connections and/or replace the mercury switch.
    2. Turn the Sensitivity Knob to 10 and move the wands from left to right. If the hitch does not travel equally in both directions, set the Monitoring Wand/Hitch switch on the control box to Monitoring Wands. If the needle does not track the position of the wands, see the section in the manual on calibrating the wand box.
