      If the probe reading indicates a bad probe after resistance tests, do not immediately dig it up. Instead: * Locate any splice in the line and cut the wire on the probe side of the splice, then retest it. * If the probe still tests bad, go to the sensor probe itself and cut the wire one foot from the probe and retest it. * If the probe continues to test bad, replace it with a CT-6-10 probe and splice the CT-6-10 to the cable using the 3-M splice kit.
