AUTOOL BT160 Automotive Circuit Tester Circuit Checker

AUTOOL BT160Product OverviewThe 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. 6-24V DC Polarity Test Open Circuit Test 10A Protection4m / 13ftLead Length10AOverload Protection220mmMain Unit Length3 YearsWarranty Support Click to enlargeBefore You Order And UseBefore You Order And UseBT160 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 OnlyUse BT160 only with 6-24V DC automotive electrical systems, including common 12V cars and 24V heavy trucks.Do Not Use On AC PowerBT160 is not designed for 110V / 220V AC household current or any system above 24V DC.Spark WarningSparks may occur at the probe tip during use. Do not operate in areas with combustible gas, dust, or explosive conditions.Inspect Before UseCheck 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 TipThe probe is sharp. Use and store it carefully, and keep the tool away from children.Do Not Open The ToolDo not disassemble BT160. Opening the tool voids the warranty, and repairs should be handled by authorized service support.Protection ReminderBT160 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.Product ComparisonProduct ComparisonCompare BT160 with other AUTOOL circuit tester models before choosing voltage range, screen display, cable length, measurement functions, and advanced diagnostic modes.BT160 FocusEntry automotive electric system tester for 6-24V DC systems, 4m lead length, 10A overload protection, polarity test, grounding test, continuity test, diode test, DC voltage detection mode, and short circuit following.BT210 UpgradeChoose BT210 if you need 9-30V operation, a simple digital display, LED light, temperature test, and basic voltage readout support.BT250 / BT260Choose BT250 or BT260 if you need a TFT color display, AC / DC voltage measurement, resistance measurement, 9 languages, diode test, grounding test, and current measurement up to 10A.

Connect the red clip to the positive terminal of the vehicle battery and the black clip to the negative terminal.Run A Quick Self-TestPress the switch to confirm LED feedback. Red indicates positive voltage and green indicates negative voltage.Probe The CircuitTouch the probe tip to the circuit contact, wire, fuse, relay, diode, or component terminal according to the selected test mode.Read LED And Buzzer FeedbackUse LED color, buzzer behavior, and circuit response to identify positive, negative, open, continuous, grounded, overloaded, or shorted conditions.Polarity TestingContact the probe tip to the tested point. A positive contact lights the red LED, while a negative contact lights the green LED.Continuity TestingConnect 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 ActivationUse 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 OperationThe 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 TestingUse grounding test mode to check whether the negative grounding of a component is good when high current flow requires reliable grounding.Short Circuit LocatingRemove the blown fuse, start from the fuse socket, follow the wiring harness, and check the wire side where green LED with buzzer appears.Use NotesUse 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.

Email[email protected] WhatsApp 86 189 2647 7404Questions And AnswersThese answers cover supported voltage, AC restrictions, LED meaning, voltage display limits, temperature and light functions, component activation, overload protection, package contents, and BT series model selection. Can BT160 Be Used On 12V Cars And 24V Trucks? Yes. BT160 is designed for 6-24V DC systems, so it is suitable for common 12V car electrical checks and 24V heavy truck electrical checks when used within the specified range. Can BT160 Be Used On 110V Or 220V AC Circuits? No. BT160 is not designed for 110V / 220V AC household current or any over-24V DC system. Use it only on 6-24V DC automotive electrical systems. Does BT160 Measure Exact Voltage Values? BT160 does not have a screen and is not the right choice for reading exact voltage values. It is intended for quick DC circuit presence, polarity, continuity, diode, grounding, and overload checks. Choose BT210, BT250, BT260, or BT280 if you need numerical voltage display or more measurement functions. What Do The Red And Green LEDs Mean? Red LED indicates positive voltage supplied or detected. Green LED indicates negative voltage supplied or detected. In continuity testing, green LED feedback indicates continuity is present. Does BT160 Support Temperature Test Or LED Light? BT160 is positioned as a simple 6-24V DC circuit tester and does not list temperature test or LED light as BT160 functions in the model comparison. Choose BT210 if you need temperature test and LED light support. How Does The Power Switch Work? The power switch can be used to output voltage during suitable tests. Press the “-” side to output positive voltage and press the “=” side to output negative voltage. Follow the manual and stop if the LED changes color with buzzer feedback during component testing. What Should I Do If Overload Protection Is Triggered? If BT160 beeps or the LED changes unexpectedly during a powered test, stop testing immediately. Check whether the tested component is defective, whether the circuit is shorted, or whether the rated current of the component is higher than the tester can support. What Is Included In The BT160 Package? Refer to the Packing List image for final package contents. The image shows the BT160 main unit, integrated lead with red and black battery clips, auxiliary ground clamp, user manual, and retail box. Which AUTOOL Circuit Tester Should I Choose? Choose BT160 if you need a compact no-screen 6-24V DC tester for polarity, open circuit, diode, grounding, and overload protection checks. Choose BT210 for a simple digital display, temperature test, and LED light. Choose BT250 or BT260 for TFT screen, AC / DC voltage, resistance, and multi-language support. Choose BT280 for smart test, multimeter, oscilloscope, relay, injector, component activation, online update, and higher-end diagnostic functions. How Long Is The Warranty?
