Key features

• •Short circuit tester automotive is a fast and efficient electrical scanning probe,Automotive Circuit Tester with Auto Electrical System Testing Functions (Digital Voltage Tester/Multimeter/Short Finder/Battery Tester/Power or Ground Supply) works on all 12-24v Sources, like cars, boats, trailers, fuel pumps, relays, and more.
• •Convenient and efficient：Directly detect the polarity of the current, the continuity of the grounding conductor or component, without re-wiring and voltage drop. Greatly improve work efficiency. Following and locate short circuits without wasting fuses.
• •Test for continuity. Test for polarity of a voltage. Check switches, relays and the on-off of diodes, fuses and circuits . Test for polarity of electric cables and plugs. Track and locate short circuits. Test for bad ground contacts.Its short-circuit protected as well as a safety measure to protect the device from overload.
• •Easy to use. Powered by the vehicle battery directly. The illumination function enables automotive technician to test the electrical system in the darkness.AC/DC Voltage Diode Current Detector unit housed in rugged and with a very friendly user interface, even a beginner can easily use it without the manual.Flexible 158in extension cord allows reaching wires in or out of the vehicle or some congested places.
• •This automotive circuit tester pen made of durable plastic. 304 stainless steel probe with pointed end and alligator clip enable easier reach to tiny and awkward areas.
