Figures 3.5 a and b. Checking
continuity of signal extension
cable with one ohmmeter lead
contacting pins in extension
cable end, and other lead
contacting corresponding test
box terminal.
5. To ohm out the wiring harness, disconnect the serial cable extension from the
implement and check continuity through the harness as shown in Figures 10a and
10b. While doing so, check the pins and the sockets of the 6-pin connector for
corrosion and fit. If necessary spread the pins with a small screwdriver to tighten fit
in sockets.

contacting pins in connector and other lead contacting corresponding coulter-electrode.
Note: intermittent electrical problems are difficult to diagnose. Flex wiring and
connectors while checking continuity.
