AUTOOL BT160

Product Overview

The AUTOOL BT160 automotive circuit tester helps reduce diagnostic time when checking 6-24V DC vehicle electrical systems. After connecting the red and black clips to the vehicle battery, technicians can probe circuits, identify positive, negative, or open states with LED feedback, activate selected components through the power switch, check bad ground contacts, and follow short circuits more efficiently.

Before You Order And Use

Before You Order And Use

BT160 is designed for automotive 6-24V DC circuits. Review the power limitation, spark warning, inspection checks, probe safety, and overload behavior before testing.

6-24V DC Only

Use BT160 only with 6-24V DC automotive electrical systems, including common 12V cars and 24V heavy trucks.

Do Not Use On AC Power

BT160 is not designed for 110V / 220V AC household current or any system above 24V DC.

Spark Warning

Sparks may occur at the probe tip during use. Do not operate in areas with combustible gas, dust, or explosive conditions.

Inspect Before Use

Check the case, probe tip, clips, and leads before use. Do not use the tester if cracks, exposed wires, or visible damage are found.

Sharp Probe Tip

The probe is sharp. Use and store it carefully, and keep the tool away from children.

Do Not Open The Tool

Do not disassemble BT160. Opening the tool voids the warranty, and repairs should be handled by authorized service support.

Protection Reminder

  • BT160 is overload protected by disconnecting the circuit and sounding a beeping alarm.
  • If the LED changes color with a buzzer during component activation, stop testing and check whether the component is defective or its rated current is higher than the tester can support.
  • Read the manual before using jumper lead operation, component activation, or short circuit locating.

Key Features

Key Features

BT160 focuses on fast visual circuit checks, polarity recognition, open circuit and continuity testing, diode status checking, grounding confirmation, short circuit following, and overload protection.

Polarity Test

Probe an unknown contact to identify circuit polarity. The red LED indicates positive voltage, and the green LED indicates negative voltage.

Continuity And Open Circuit Test

Check whether a tested wire, fuse, relay, switch, or circuit path is continuous or open by using the auxiliary ground lead and probe tip.

Diode Test Mode

Quickly test the working status of a diode assembly and determine whether the circuit is open or continuous.

Grounding Test

Check whether the negative grounding of a component is good. Green LED with buzzer feedback indicates good grounding under the correct test setup.

Short Circuit Following

After removing the blown fuse, use the probe to help follow the wiring harness and locate the shorted side or overloaded component.

Current Overload Protection

When overload or excessive current is detected, BT160 automatically opens circuit protection and beeps to reduce unnecessary losses.

How To Use

How To Use

Connect BT160 to the vehicle battery, select the appropriate test method, observe LED and buzzer feedback, and stop testing if overload protection is triggered.

Connect To Battery

Unroll the leads. Connect the red clip to the positive terminal of the vehicle battery and the black clip to the negative terminal.

Run A Quick Self-Test

Press the switch to confirm LED feedback. Red indicates positive voltage and green indicates negative voltage.

Probe The Circuit

Touch the probe tip to the circuit contact, wire, fuse, relay, diode, or component terminal according to the selected test mode.

Read LED And Buzzer Feedback

Use LED color, buzzer behavior, and circuit response to identify positive, negative, open, continuous, grounded, overloaded, or shorted conditions.

Polarity Testing

Contact the probe tip to the tested point. A positive contact lights the red LED, while a negative contact lights the green LED.

Continuity Testing

Connect the auxiliary ground lead to one side of the tested wire and the probe tip to the other side. Green LED means continuity is present.

Component Activation

Use the power switch to apply positive or negative output under the correct setup. Stop immediately if the LED changes color with buzzer feedback.

Jumper Lead Operation

The black clip and auxiliary ground lead are directly connected through the unit, allowing BT160 to work as a long jumper test lead in suitable checks.

Grounding Testing

Use grounding test mode to check whether the negative grounding of a component is good when high current flow requires reliable grounding.

Short Circuit Locating

Remove the blown fuse, start from the fuse socket, follow the wiring harness, and check the wire side where green LED with buzzer appears.

Use Notes

  • Use BT160 only on 6-24V DC systems.
  • Do not use BT160 with AC current or over-24V DC circuits.
  • When component activation causes the LED to turn green with buzzer sound, stop testing and inspect the component or circuit load.
  • For short circuit following, mark the wire color or identification code and inspect connected components individually if needed.
