AUTOOL BT160 · 6V–24V COMPONENT ACTIVATION POWER PROBE
AUTOOL BT160 Automotive Electrical Circuit & Wiring Harness Tester
Upgrade from passive test lights: instantly identify polarity, locate short circuits and bad grounds, and energize electrical components directly on 6V–24V vehicles.
- 6V–24V DC Vehicles
- 10A Overload Breaker
- 4m Cable · 6-Month Warranty
Engineered for Professional Workshop Demands
The AUTOOL BT160 is built to deliver speed, accuracy, and durability in busy service bays.
Instant Polarity Identification (Red/Green LED + Buzzer)
Touching a (+) positive wire illuminates the Red LED with a high-pitched beep; touching a (-) ground wire illuminates the Green LED with a low-pitched tone.
Direct Component Activation (Power Probe Rocker)
Press the rocker switch forward (+) or backward (-) to send battery power or ground directly to cooling fans, fuel pumps, starter solenoids, and bulbs.
10A Automatic Resetting Circuit Breaker
If the energized component draws more than 10 Amps or has a dead short, the internal thermal breaker trips immediately and resets automatically once cooled.
Continuity, Diode & Bad Ground Testing
Use the auxiliary ground clip to test switches, relays, fuse continuity, alternator diodes, and high-resistance chassis grounds.
ENERGIZE COMPONENTS IN PLACE
Isolate Faulty Parts vs. Faulty Wiring in Seconds
When a radiator fan, horn, or wiper motor fails, power it directly at the connector with the BT160. If it runs, the fault is in the vehicle harness/relay; if not, the component itself is dead.
- Test radiator fans, blower motors, and fuel pumps without removal
- Run power window motors up and down by reversing switch polarity
- Verify headlights, brake lights, and trailer connector pins solo
SAFE SHORT-CIRCUIT PROTECTION
10A Thermal Breaker & 4-Meter Heavy-Duty Cable
Unfused jumper wires can melt harnesses. The BT160 protects both the vehicle and technician with an automatic 10A overload breaker.
- Auto-resetting breaker—no glass or blade fuses to replace
- Auxiliary ground lead for off-vehicle bench testing of relays and switches
- 4-meter cable reaches trailer hitches and rear lighting assemblies easily
EVERYDAY WORKSHOP ESSENTIAL
Compatible with 6V Motorcycles, 12V Cars & 24V Trucks
Lightweight, rugged, and intuitive, the BT160 saves hours of electrical troubleshooting in any service bay.
- Sharp stainless steel probe pierces oxidation cleanly
- Loud dual-tone buzzer for eyes-free testing in noisy bays
- Backed by a 6-month official Otoeko warranty

Workshop Application & Operating Guide
Recommended 4-step standard operating procedure for accurate results.
Clip to Vehicle Battery
Connect the red clip to battery (+) and black clip to (-). Rock the switch forward (Red LED + beep) and backward (Green LED + tone) for self-test.
Probe Circuit Polarity
Touch the probe tip to the wire: Red LED indicates (+) voltage, Green LED indicates (-) ground, and no LED indicates an open circuit.
Activate Electrical Loads
Clip the auxiliary ground lead to component negative, touch the probe to positive, and press the switch forward (+) to energize.
Check Continuity & Relays
Touch the auxiliary clip and probe tip across a disconnected fuse, switch, or wire; a Green LED confirms continuity.
Conventional Methods vs. Professional Diagnostics
How precision engineering eliminates guesswork and comebacks.
Conventional / Basic Methods
- Traditional test lights cannot supply power to test components
- Unfused jumper leads risk melting wires during a short circuit
- Cannot distinguish between an open wire and a ground wire
- Short cords require extension jumpers to reach rear lights
With AUTOOL BT160
- Energizes fans, pumps, and motors directly with (+) or (-) power
- 10A automatic breaker trips safely on any short circuit
- Instantly differentiates (+) positive, (-) ground, and open circuits
- 4-meter cable reaches from battery to rear bumper without extensions

Frequently Asked Questions
Key technical questions from technicians and workshops about the AUTOOL BT160.
Does the BT160 have a digital voltage screen?
The BT160 uses instant Red/Green LEDs and audio tones for fast polarity and activation testing. If you need a color LCD showing exact voltage, resistance, and frequency, choose the AUTOOL BT260 or BT280.
Can I use it on 24V heavy-duty trucks?
Yes, it supports 6V to 24V DC electrical systems.
What happens if I accidentally power a shorted wire?
The internal 10A thermal circuit breaker trips immediately to protect the harness and resets automatically after cooling for a few seconds.
Which components can I activate?
Fuel pumps, radiator fans, starter solenoids, power window motors, wiper motors, horns, relays, and bulbs.
Should I apply power to ECU computer pins?
You can safely probe polarity, but never press the power switch to inject (+) current directly into ECU/ECM or airbag module pins.
What is the warranty period?
It comes with a 6-month official Otoeko warranty.
