8.Find and repair the short to frame or faulty component.

NOTE: The steer LEDs indicate what coil is being tested. To change the coil being tested, press the horn button. The battery LEDs indicate the signal strength of each coil. See Figure6-7.

4.Check the near wire coil pairs and verify the signal strengths are approximately the same.

5.Check the 4 guidance coils (2 right, 2 left) and verify the signal strengths are approximately the same.

6.Drive the lift truck diagonally across the guide wire to monitor the guidance channels. The signal strength should increase as the coil approaches the wire, and decrease as the coil moves farther away from the wire.

a.If one or more channels are low, re-learn the guidance offsets (page3-10) and repeat the test.

b.If one or more channels are still low, troubleshoot per “Guidance Manager Fault Codes” on page6-19 .

7.Drive away from the wire and operate all lift truck functions, including travel, lift, steering, horn, and any optional equipment while checking the guidance coils. If the guidance signal increases due to the operation of any of these functions, there is a short to frame in the lift truck or electrical noise generated by motors due to bad brushes, worn commutators, or faulty suppressors. The sensor coils are picking up this noise.
