OTC 3630 Continuity Tester for Automotive Wiring

The OTC 3630 is a battery powered ohmmeter built to test non-live electrical circuits. Technicians use it to locate broken wires, bad grounds and blown fuses on cars, trucks and motorcycles. The tool ships ready to work with one AAA battery and a low voltage replaceable bulb included.

Stainless Probe and 12 Foot Coil Cord for Shop Use

A heavy-duty stainless steel probe with an insulated shaft resists wear while protecting the user. The heavy-duty clip uses a positive soldered connection for reliable contact. A slim, ergonomically designed clear handle fits comfortably during extended diagnosis. The 12 foot red coil cord stretches across engine bays without tangling.

Replaces Guesswork When Chasing Intermittent Faults

This tester replaces visual inspection and multimeter probing on de-energised circuits where speed matters. The jump is worth it when you need audible or visual confirmation of continuity without powering the system. It is not suited for live voltage measurement or high-energy circuit analysis.
