Why do we need an automotive circuit tester?

The types and causes of automotive circuit failures are diverse, and the circuit systems are complex. This makes it much more convenient to have an automotive circuit tester to accurately detect and diagnose various wiring faults in the car's wiring, as well as aging wiring and other conditions. Meanwhile, the circuit tester can also detect possible future failures of the automotive circuit systems and provide reliable information for troubleshooting.

Why do we choose AUTOOL BT160 automotive circuit tester?

AUTOOL BT160 is easy to use. After connecting it to the car battery, you can conduct positive or negative battery current to the probe by pressing the switch forward or backward. This unit comes with short-circuit protection, which can immediately check for poor grounding. It allows to track and locate short circuits.

More Details

Quick self-test

AUTOOL BT160 circuit tester can perform quick self-test on vehicle circuit system.

Test Procedure: Unfold the tool's cable and clip the red clip to the positive end of the vehicle battery and the black clip to the negative end of the vehicle battery; press the front (-) of the power switch and the LED should glow red, press the rear (=) and the LED should glow green, indicating that the tool is now ready for use. If the LED does not come on, the clip may be poorly connected or the unit may be damaged.

Short circuit tracking and location

In most cases, a short circuit of a component or a momentary overload will cause a fuse or circuit to blow and a circuit breaker to trip. The AUTOOL BT160 circuit tester can search and locate the cause of a short circuit where it occurs.

Test Procedure:

Connect the red clip to the positive end of the vehicle battery and the black clip to the negative end of the vehicle battery; press the button to the "-" side, the LED should glow red and provide positive voltage. Remove the blown fuse from the fuse box and trace from the two terminals of the fuse socket. If the LED glows green and the buzzer sounds, it indicates a short circuit or overload component on this side, please note the color or identification code of this wire. Follow the wires along the harness as far as possible, find the color-coded wire in the harness and expose it, then cut the wire. Follow the direction of the shorted wire and repeat the process until you find the short.

Test components in vehicle electrical systems

The AUTOOL BT160 circuit tester is capable of testing components in a vehicle's electrical system.

Test procedure: unfold the cable, connect the red clip to the positive end of the vehicle battery and the black clip to the negative end of the vehicle battery; connect the auxiliary ground wire to the negative end of the component under test; press the button to the (-) side and the LED lights up red; activate the component by connecting the probe tip to the positive terminal to test the component. If the LED turns green, audible through the buzzer, stop the test and check if the component is defective or if the component is rated for higher current than this tester.

Caution: Do not operate the unit in areas with combustible gases, dust, or explosive atmospheres; do not allow for use with AC power and DC circuits exceeding 24V.

Jumper function

AUTOOL BT160 circuit tester is equipped with jumper function. The black battery clip of the tester and the auxiliary grounding wire clip are physically fixed and connected, user can disconnect from the original line connection (in case of control switch or open circuit), and use the line of the two black clips on the tester as the connection for testing and maintenance.
