Automotive Circuit Tester with Digital Display
Find Out What The Circuit Is Doing Before You Start Replacing Parts.
Combine automotive circuit checking and common relay testing in one digital handheld toolβbuilt for the electrical problems hiding inside crowded engine bays and fuse boxes.


The Hard Part Is Usually Finding Where The Electrical Problem Starts.
A fuse box full of relays and wiring can turn a simple symptom into a long search. A dedicated tester helps turn that search into a more structured diagnostic process.
Get measurable feedback instead of relying only on visual inspection.
Check compatible common automotive relay formats from the same tool.
An integrated light helps illuminate the immediate test area.
Move Between Circuit Checks And Relay Checks Without Rebuilding Your Setup.
The dual-function design combines electrical circuit testing with support for common 4-pin and 5-pin automotive relays, helping reduce the number of separate diagnostic tools on the bench.


Keep One Hand On The Tester And The Other Where The Work Is.
The handheld body, long lead and probe-oriented layout are designed around real automotive diagnosis where space is limited and components are often awkward to reach.
Keep the display and controls together in your working hand.
Reach around larger engine bays and electrical compartments.
Add local illumination around the probe area.
One Tester For More Than One Kind Of Vehicle.
With DC circuit testing across the listed 3.5β36V range and relay support for 12V and 24V systems, the tester is suited to a wider range of compatible automotive electrical work.

Spend Less Time Swapping Tools. Spend More Time Following The Fault.
Designed for listed DC automotive circuit testing from 3.5V through 36V.
Supports compatible standard 4-pin and 5-pin automotive relays.
The built-in LED helps when the connector you need is buried in a darker work area.
