  • Page 2 1970s. The CT1000 is the first Cable Testing System ever developed that allows a single user to fully test and isolate trouble with cables associated with the electronics involved today on field vehicles and implements without removing the cable harness.
  • Page 3 Testing Cables Using an Ohm Meter Testing cables when the technician only has access to one end of the cable for a meter connection can be done with a traditional Ohm Meter or continuity tester. Completely testing a harness can be very time consuming and it’s very easy to miss intermittent connections.
  • Page 4 When checking for shorts between wires check the wires one at a time. Use one wire as the COMMON. We’re using the BLACK wire #1 as common. To check wire 5 for shorts hook the meter leads to 1 and 5. Then hook connect jumpers from wires 1 to 2, 1 to 3,and 1 to 4.
  • Page 5 The CT1000 is a cable testing system. When testing the cable above the CT1000 would connect at the MMR connection. TERMINATORS are installed at individual connectors involved in the test.
  • Page 6 Panel Layout and Component Details Set Number of Terminators Charging Jack wires 1,2,3 Wires 1-12 Control Sounder Alarm and Wires on/off Switch 13-24 Control Input Connectors Power On/Off and Chassis Alarm Status and Battery Level Ground Alarm Control Wires 1-24...
  • Page 7 The charger can be used while the CT1000 is in use. The CT1000 will continue to operate with just slightly above 10Volts, but it should be charged when below 12V.
  • Page 8 When testing for shorts between wires, the user can SWITCH to LEFT to create a short on a particular wire. There is more information in the Using the Tester Section of the CT1000 Manual. The Wire Alarm Status Lights are also split into groups of twelve.
  • Page 9 Becoming Familiar with the CT1000 We use the following procedure to “Proof” or final test the CT1000 before shipping. Going through at least part of the procedure will help give you a solid feel for how it is wired and how it works.
  • Page 10 LED lights for wires 13-24. The sounder comes on unless switched off. Plug in the CHARGER and verify the 13V LED comes on indicating a charge above 13 volts. The CT1000 can be used in the field with the charger running when needed.
  • Page 11 Set the Wire back to NO TEST. In our case wire #17 The GREEN ALL OKAY LED for wires 13-24 comes on indicating NO CURRENT PROBLEM. But the RED ALARM led and the sounder continue until RESET. Press the RESET BUTTON to silence the alarm. Turn ON ALL WIRES starting with one through 12 verifying that as a wire is activated the OPEN, YELLOW LED comes on indicating the correct error and number sequence.
  • Page 12 The SOUNDER can be turned OFF for the tests. ALL WIRES will show YELLOW OPEN condition Attach a TEST LEAD from the CHASSIS GROUND or COMMON connection to each wire on the 16 PIN INPUT CONNECTOR. VERIFY GROUNDING EACH WITH 1 THROUGH 12 MATCHES ERROR INDICATORS 1 THROUGH 12.
  • Page 13 After confirming ALL INPUT pins as correct, switch the WIRE SHORT SWITCHES to SHORT and verify all match switch with wire indicator. CHECK ALL 24 WIRES Set all switches back to NO TEST and RESET ALARMS Turn the SET TERMINATOR SWITCHES from position one through five. The alarm will sound when dialed off position 1.
  • Page 14 When completed the CT1000 is ready for the field. Turn the power switch “OFF” when completed.
  • Page 15 Cables and Terminators for the CT1000 Connecting the CT1000 to a cable requires an adapter cable to go from the cable harness being tested and the CT1000. Terminators are also required. You can build them yourself or purchase from Ag-Tester or a company offering the CT1000 cable testing system.
