Key Features
-
Polarity at a Glance
The LED turns red on a positive wire or pin and green on a negative one.
-
Ground Check
A good ground turns the LED green with a beep; a poor ground leaves it red and silent.
-
Continuity Testing
Checks switches, relays, diodes, fuses and wiring for an open circuit.
-
Component Activation
Powers a component in or out of the vehicle, and the LED and buzzer show if it is faulty or draws more current than the tester is rated for.
-
Short Tracing
Helps follow a wiring fault to the damaged wire and the point where it shorts.
-
Built-In Breaker
If current goes above 7A, the internal breaker trips and the buzzer sounds to protect the tester.
-
Auxiliary Ground Lead
The black clip and auxiliary ground lead pass straight through the unit, so they can serve as a long jumper lead when the other clip is left off the battery.
