Description: EM415PRO detects and alerts you immediately when a circuit is open. You can quickly and easily locate short circuits, open connections, broken wires, current leaks, and trace wires. It allows you to identify intermittent circuit issues by flexing wires or connectors and listening for changes in the receiver tone, enabling broad tracing or precise pinpointing of the problem location. The device includes a direction indicator to show the location of the short, eliminating guesswork. This professional tool works on all types of circuits with DC voltages between 6 and 42 volts, such as those found in automobiles, trucks, tractors, boats, RVs, and more. With its wide operating voltage range, it is suitable for use in vehicles, including those with 42-volt systems. Key Functions: - Locate short circuits and open circuits - Test continuity of cables or wires - Trace cables or wires and diagnose break points - Receive tone signals on cables or wires (including telephone lines) - Identify the status of a working telephone line (clear, ringing, busy) - Send a single solid tone or dual alternating tone to target cables or wires Item Specifications: - Power: Two 9V batteries (not included) - Item Width: 4 cm - Material Type: Coiled steel - Item Height: 15 inches - Item Length: 17 cm - Item Type: Electrical Testers & Test Leads This instrument is designed to identify and trace wires or cables without damaging insulation. It can also be used to check for short circuits and locate open circuits. The kit includes a S and a Receiver. Features: - Wire tracing possible inside bundles, conduits, behind panels, under carpets, and within upholstery - Easy to use: connect the transmitter in series with the circuit or wire under test (e.g., in place of a blown fuse, across a connector, in series with an open wire, or a light bulb socket), then scan with the receiver’s flexible probe to find the fault - Operates on DC voltages from 6 to 42 volts - Internally protected against power surges and overloads - 7-inch flexible probe enables access to wires in tight spaces - Transmitter and Receiver LEDs indicate open or short circuit conditions - Adjustable sensitivity for various tracing conditions - No wire piercing required — uses non-contact technology How to Use the Probe: The receiver’s probe is made of coiled steel and can be bent as needed to reach wires in tight or difficult areas. For optimal signal detection, position the probe tip (black cap) perpendicular (90 degrees) to the wire being traced, either above or below it. Signal reception may vary based on circuit characteristics and sensitivity settings. Package Includes: 1 x Automotive Short and Open Circuit Finder
