6/12V Mini Circuit Tester

The OEMTOOLS 25936 is a hand-powered probe for 6 volt and 12 volt vehicle electrical systems. It locates live circuits, finds shorts and verifies grounds. The tool suits professional technicians and DIY owners who need a compact tester for bench work or tight engine bays. It is not for high-voltage hybrid or EV diagnostics.

6 ft Hi-Vis Coil Cord

A high-visibility coil cord stretches from 36 to 72 inches, giving reach across the vehicle without excess slack. The bright test bulb provides clear indication in low light. The tester handles standard automotive primary circuits but cannot measure voltage values or diagnose complex data-bus faults.

Threaded Probe with Alligator Clip

The sharp stainless steel probe is threaded to accept the included alligator clip for hands-free grounding. A moulded strain relief protects the cord connection and an insulated heavy-duty clip secures the lead. No carry case or replacement bulbs are supplied.

Questions about this item

Will the 25936 tester work on a classic 6 V vehicle system I still maintain?

Yes, the tester is designed for both 6 Volt and 12 Volt electrical systems, so it will operate on the older 6 V wiring you are keeping.

How can I confirm the 25936 is lighting correctly after I connect the clip?

The high-intensity bulb in the probe will illuminate brightly when the circuit is live, giving immediate visual confirmation.

Does the 25936 come with the alligator clip, or must I buy it separately?

The kit includes a threaded alligator clip and an insulated heavy-duty clip, so no extra purchase is needed for basic testing.
