Stop Switching Between Four Different Tools
Test power, polarity, fuses, electrical components and compatible 4-pin or 5-pin relays with one compact automotive circuit probe.
⚡ Check Power & Polarity
🔧 Test Fuses & Components
🔌 4-Pin / 5-Pin Relay Test
Less Guessing. Faster Testing.
One Electrical Fault Shouldn't Need A Bench Full Of Tools
Keep the test light, power probe and separate relay tester from slowing down a simple diagnosis.
3-in-1 Testing
Move from checking voltage to fuses, components and relays with one handheld tool.
Built For The Fuse Box
See The Circuit Status At A Glance
The digital display and polarity indicator lights help you identify voltage and positive or negative circuits without constantly reaching for another meter.
Three Jobs. One Tool.
Find The Problem Without Replacing Good Parts
Read Circuit Voltage
View the electrical reading directly on the built-in digital display.
Check Fuses Faster
Probe both fuse test points to quickly help identify a blown fuse.
Test Common Relays
Use the integrated 4-pin and 5-pin positions to check compatible automotive relays.
Power The Component. Confirm The Fault.
The positive/negative switch and auxiliary ground lead help test compatible low-voltage components such as lights, horns and motors.

Simple Workflow
Connect. Probe. Diagnose.
Connect To The Battery
Attach the red and black clamps to the correct battery terminals.
Probe The Circuit
Touch the metal probe to the intended test point and read the display and indicators.
Narrow Down The Fault
Check power, ground, fuses, components or a compatible relay as required.

Questions & Answers
Good To Know
Does it completely replace a multimeter?
No. It combines several common automotive troubleshooting functions, but advanced electrical diagnosis may still require a professional multimeter or scan tool.
Can it test fuses without removing them?
Many automotive blade fuses have exposed test points. Touching both sides can help determine whether power passes through the fuse.
Can it test every relay?
No. Use only compatible automotive relays that match the tester's supported 4-pin or 5-pin configuration and follow the included instructions.
Is it suitable for beginners?
The integrated display and indicators simplify common checks, but users should still understand basic automotive electrical safety and consult the vehicle service information.
