2. Inspect nylon insulation slides under coulter-electrode mounting brackets. These nylon

insulators may become worn or brittle, or may slip out from under mounting bracket. Repair

and replace as necessary. Make sure that all electrode coulter U-bolts are properly

tightened to clamp mounting bracket and insulation tightly to frame.

3. Disconnect signal cable from instrument or front of frame. Check so see that no metal part

of the any coulter electrode is in contact with the implement frame. This may be by visual

inspection or by connecting one lead of an ohmmeter to the individual coulter electrode, and

the other to a grounded fastener on the frame. If the coulter electrode is properly isolated,

no reading will be obtained. Make sure that all electrode coulter clamp bolts are properly

tightened to prevent lateral movement of the coulter electrode.
