🔧 20A Fuse Current Tester – Check Automotive Circuits Without Cutting Wires
Measure Current at the Fuse Box Without Cutting Into Wires.
Plug into a compatible fuse socket and read DC current directly on the digital display — a practical way to check automotive electrical circuits without piercing wire insulation.
Need a Current Reading? Start at the Fuse Box.
Automotive electrical checks can become frustrating when access is tight or the only obvious option appears to be probing into wires. This tester uses the fuse socket as the measurement connection point.
Avoid Piercing Insulation
The fuse-socket connection means you do not need to intentionally puncture the vehicle's wire insulation just to obtain a current reading.
Work Where the Circuit Is Accessible
Connect at a compatible fuse position instead of chasing the same circuit deeper into the vehicle harness.
Match. Connect. Read.
The tool uses a wired fuse adapter to place the meter into a compatible fuse circuit for current measurement.
Check the Circuit
Identify the fuse position and confirm the circuit information in the vehicle documentation.
Connect the Adapter
Use the suitable supplied adapter with a compatible blade-type fuse socket.
Read the Current
View the DC current reading directly on the digital LCD display.
Bright Display. Better Viewing Angle.
The digital LCD combines a blue backlight with a pop-up viewing design, helping you position the screen where it is easier to read.
Current value is shown directly on the LCD screen.
Adds screen illumination for darker work areas.
Adjust the screen position for a more convenient viewing angle.
More Useful Features Right on the Tool.
A compact body, battery-powered operation and integrated work light make the tester easier to keep nearby for automotive electrical checks.
LED Work Light
Helps illuminate darker areas around the vehicle.
Battery Powered
Uses one 12V 23A battery, included with the tester.
Fuse Adapters
Supplied adapters support connection with compatible fuse sockets.
Portable Format
Compact enough to keep with automotive diagnostic tools.
Useful Around the Fuse Box, Dashboard & Engine Bay.
Use the tester when you need to inspect DC current through a compatible fused automotive circuit without cutting into wiring.
Specifications
Before You Start Testing
Do I need to cut or pierce the vehicle wires?
The tester is designed to connect through a compatible fuse socket using its wired adapter, so the measurement process does not require intentionally cutting or piercing wire insulation.
What does the tester measure?
It is designed for DC current measurement. The listed measurement range is 0.01A to 19.99A with a maximum of 20A.
Will it work with every vehicle?
Fuse styles vary between vehicles. Check the fuse type in your vehicle and make sure it is compatible with one of the supplied adapters before use.
Does the screen have a backlight?
Yes. The digital LCD uses a blue backlight and the screen has a pop-up design that allows the viewing position to be adjusted.
Does it include a work light?
Yes. The product information lists an integrated LED light with a dedicated light button.
Is the battery included?
Yes. The listed package configuration includes one 12V 23A battery for the tester.
