1797 Automotive Circuit Relay Tester & Digital Test Light Kit, Car Electrical 20A 48V High-Precision Blade Fuse Current Checker with LCD, 5–90V Power Probe Voltage Tester (Battery Not Included)
ULTIMATE DIAGNOSTIC DUO: Stop guessing and start diagnosing. This automotive electrical tester kit includes a relay tester and a test light. Essential tools for DIYers and mechanics to quickly identify voltage issues, abnormal current draw, and faulty circuits in most vehicles.
DETECT ABNORMAL CURRENT DRAW: The car fuse tester measures current directly through fuse slots—no complicated multimeter setup required. Perfect for tracking parasitic battery drain, diagnosing electrical problems, and checking circuit load quickly.
CLEAR READINGS IN THE DARK: Stop working blind under dark dashboards or inside engine bays. This automotive circuit tester features a built-in LED to brightly illuminate hidden fuse boxes, while the backlit LCD screen ensures your current readings are instantly visible.
DIGITAL TEST LIGHT WITH ACCURATE VOLTAGE DETECTION: The power probe voltage tester measures 5–90V DC with clear digital voltage display (±0.1V accuracy). Instantly identify battery voltage, circuit faults, and electrical connections in seconds.
POLARITY INDICATOR FOR FAST CIRCUIT CHECKS: Red light indicates positive (+) and green light indicates negative (−), helping you quickly identify polarity when testing wiring, terminals, switches, or connectors.
70-INCH EXTENDABLE WIRE: Features an insulated ABS handle and a stainless steel probe for safe point-contact testing. Includes an alligator clip for secure grounding and a coiled spring wire that stretches up to 70 inches to reach distant automotive circuits.
COMPLETE READ-TO-TEST KIT: Includes 1 x automotive test light and 1 x car relay tester with both standard & mini adapter plugs. Note: This car circuit tester requires one 23A 12V battery (not included).
