AUTOOL BT260 Color TFT Automotive Electrical Circuit & Harness Tester
See exact voltage drops, coil resistances, and sensor frequencies on a bright color TFT display while activating 12V–24V components across a massive 12-meter working radius.
- Color TFT LCD · 0–65V
- 6m + 6m (12m) Cable
- 1-Year Official Warranty
Engineered for Professional Workshop Demands
The AUTOOL BT260 is built to deliver speed, accuracy, and durability in busy service bays.
4-Mode Digital Diagnostics (DCV, ACV/Hz, Resistance, Diode)
Switch seamlessly between DC Voltage (0.1V resolution), AC Voltage/Frequency/Min-Max, Resistance (0–200 kΩ), and Diode/Continuity modes.
Direct Component Activation with 10A Protection
Supply (+) battery power or (-) ground directly to cooling fans, fuel pumps, relays, and lights; the 10A thermal breaker trips automatically on shorts.
12-Meter Total Cable Reach & Dual Power Adapters
Includes a 6m main cable plus a 6m extension cable, along with both battery alligator clamps and a 12V/24V cigarette lighter adapter.
Dual Front LED Worklights & Red/Green Polarity
Bright dual LEDs illuminate dark under-dash fuse panels while Red/Green indicators and audio tones confirm polarity instantly.
DIGITAL MULTIMETER + POWER PROBE
Catch Voltage Drops & High-Resistance Faults Instantly
Unlike basic LED test lights that still glow on a corroded 8V wire, the BT260 displays exact 0.1V readings and resistance up to 200 kΩ.
- Pinpoint voltage drops and corroded chassis grounds immediately
- Monitor sensor AC frequency (Hz) and Min/Max voltage swings
- Measure relay coil, injector, and sensor resistance (0–200 kΩ)
BUILT FOR CARS & HEAVY TRUCKS
12-Meter Cable Kit & Dual Power Options
Testing trailer lights on a semi-truck or bus is effortless with the included 6m extension cable extending total reach to 12 meters (39.3 ft).
- 6m main lead + 6m plug-in extension cable included in the case
- Power via vehicle battery clamps or cab cigarette lighter socket
- Removable stainless probe tip and rugged blow-molded carrying case
WORKSHOP SAFETY & ERGONOMICS
1–10A Thermal Circuit Breaker & Dual LED Headlights
Work confidently in dark engine bays and under dashboards with built-in illumination and automatic overload protection.
- Auto-resetting 10A breaker prevents harness damage
- Oil- and impact-resistant housing built for daily shop use
- Backed by a 1-year official Otoeko warranty

Workshop Application & Operating Guide
Recommended 4-step standard operating procedure for accurate results.
Connect Power Adapter
Plug into the 12V/24V battery using the alligator clamps or cigarette lighter adapter; attach the 6m extension if needed.
Select Diagnostic Mode
Press the Mode button to cycle between DC Voltage, AC Signal/Hz, Resistance (Ω), and Diode/Continuity.
Measure Voltage & Resistance
Probe the circuit to read live voltage down to 0.1V and identify voltage drops or bad grounds.
Activate Components
Rock the power switch forward (+) or backward (-) to energize motors, relays, and bulbs up to 10A.
Conventional Methods vs. Professional Diagnostics
How precision engineering eliminates guesswork and comebacks.
Conventional / Basic Methods
- LED-only probes cannot reveal partial voltage drops (e.g., 8.5V on a 12V line)
- Cannot measure resistance (Ohms) or sensor frequency (Hz)
- Short 4m cables cannot reach the back of trucks or trailers
- No built-in flashlight or protective storage case
With AUTOOL BT260
- Color TFT LCD shows exact 0–65V voltage with 0.1V resolution
- Measures 0–200 kΩ resistance, diodes, and AC frequency (Hz)
- 6m + 6m (12m total) cable reaches semi-truck trailers easily
- Includes dual LED headlights, cigarette adapter, and hard case
