Tester and Adapter Set For Relays

Tester and Adapter Set for Relays




The Relay Adapter provides a platform to test a relay while allowing the relay to remain active in a circuit.
The adapters included enable different pin configurations of relays to be tested using a single tester.




Remove relay and compare plug in adapter with plug pattern on relay. Choose correct adapter (Fig. 33/1).




Fit adapter to Measuring bridge, noting the marker arrows (A). Fit the relay to the measuring bridge (Fig. 33/2).




Plug the assemble measuring bridge into the socket of the relay to be checked. lest using a multimeter. See the circuit diagram and testing instructions for subsequent procedure (Fig. 33/3).

"V" Cables




"V" cables are available in different versions depending on the system being diagnosed. Always refer to the most recent Service information for the required special tools.

"V" cables are only used with the 26 pin breakout box to access input and output signals of peripheral modules and systems.

- The appropriate cable is distinguished by the color of the connector end.
- The color will match the particular modules connector color. Unless the color matches, the cable will not fit the connector on the module being tested.
- Each colored "V" cable has a series of alignment tabs that will only fit it's particular module or system.

"V" cables with ELO connectors are also being used with the 26 pin breakout box. These cables are unique in that they have a locking arm on the component side of the cable. They are light green in color; and the number of pins will vary depending on the system being tested.

"V" harness adapters were introduced with the E38. These also have light green ELO connectors on the component side, but they do not require a breakout box.
There is a black plug on one side with same number of pins as the component being tested.
The plug has numbers stamped on it's side that corresponds with the pins on that particular component.
You access the signals by plugging the test equipment directly into those pin numbers.

As new systems and components are being introduced, new breakout boxes and cables will also be introduced.

Always remember to refer to the most recent service information in Service Information Bulletins for the latest diagnostic tools and procedures.
