Automotive Test Lamps and Multifunction Testers

Automotive test lamps and multifunction testers help repair shops quickly troubleshoot faults in standard automotive electrical circuits. Among other things, they enable the testing of polarity and continuity, the detection of faulty ground connections, and the functional testing of relevant electrical components.

Leitenberger Autotestgeräte offers the multifunction testers AZ 172 for 6 to 24 V and AZ 173 for 12 to 24 V for this purpose. Depending on the test task, voltage or ground can be applied precisely via the test probe. This allows, for example, relays, lights, fuel pumps, or window regulator motors to be tested and helps pinpoint faults in the wiring.

Both devices feature a 6-meter-long connection cable and a resettable 7.5-A thermal fuse. The AZ 173 additionally provides illumination of the test point and an audible polarity indicator.

The testers were developed for applications in traditional automotive electrical systems. They are not intended for measurements or for applying voltage or ground to control units and sensitive on-board electronics.
