3. Test Load installed display showing proper EC readings for 2000XA and 3100 Procedure 2 Testing Electrical Continuity Perform this test daily or every 10 hours of data collection to ensure you are obtaining reliable data and whenever EC data is questionable The purpose of this test is to insure that each coulter electrode has an uninterrupted signal path from the EC Surveyor to the disk blade Think of each coulter electrode and its wire path as a channel On a 3100 and 3150 there are 6 signal channels that must be clear and isolated from each other 4 on a 2000XA You will first test the complete pathway for each channel each coulter electrode One easy to take reading for each channel tests the cable wiring harness and each coulter electrode and disk blade If no problems surface during this test there is no need to test individual components This test should take only a couple of minutes to perform To perform this test you will need the EC Signal Test Box part 10759 and an ohmmeter sometimes referred to as a multi meter or voltmeter Make sure the meter is set to ohms If a range of ohms is available choose the lowest setting ohms rather than kilo or mega ohms If unfamiliar with ohming out or resistance testing make a few trial tests before performing the Veris signal test procedure Touching the meter leads together will display a zero resistance reading touching two places on the same piece of metal will pro

7. 3 If you see a gt 2ohms reading on any channel separate sure seal connector and insert one ohmmeter lead in the end of wiring harness and the other lead in the corresponding terminal on the Test Box If reading is 2 ohms at that point the problem is not with the wiring harness or signal cable extension It is most likely in the terminal connector wire Check resistance in it by placing one ohmmeter lead on the coulter wire terminal bolt and the other lead in the end of the terminal wire socket Replace connector wire PN 14226 as necessary Figures 3 4 ab a Separating sure seal connector b Testing terminal connector wire 4 If there is a gt 2 ohm reading in the signal cable harness or signal extension cable visually inspect the wiring harness and cable extension for damage If a visual inspection doesn t reveal a problem you will need to test continuity of the wiring harness and cable You will need to ohm these cables out individually Disconnect signal extension cable from implement and insert ohmmeter leads into sockets as shown below 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 p
