After a simple hook-up of it to the vehicle's battery, an automotive technician can conduct a positive or negative battery current to the tip by rocking the power switch forward or backward. The circuit tester is short-circuit protected and can test for bad ground contacts instantly. It allows you to follow and locate short circuits. It can also test for continuity with the assistance of its auxiliary ground lead. FEATURES Overload Protection The circuit tester is equipped with a built-in circuit breaker for overload protection. After the circuit breaker trips, it will be reset automatically. 16ft Cable Length The cable length is approximately 5m (16ft), allowing you to easily test any electrical system. No Extra Battery Needed The circuit tester is powered by the 12V vehicle battery directly. allsun EM285 Car Electrical Tester PACKAGE INCLUDES 1pc x Box 1pc x Instruction Manual 1pc x Flexi Extension Cable 1pc x Crocodile Clip 1pc x Wire Probe 1pc x Back-Probe Red Battery Clip Black Battery Clip Probe LED Indicator Power Switch It includes a front part "-” and a rear part "=”.

APPLICATIONS Quick Self-test Continuity Testing Activating Components out of the Vehicles Electrical System Testing Trailer Lamps and Connections Activating Electrical Components Jumper Lead Feature Checking for Bad Ground Contacts Polarity Testing GENERAL SPECIFICATION Review: Useful piece of kit - Item arrived promptly and was exactly as described. I like the variety of options this particular tester offers although as advised in the instructions you need to ensure it’s in the correct mode before testing units to ensure you don’t cause a short in certain test modes. Overall I’m very happy with the purchase, the price and performance to date. Review: Make sure when connecting that polarity is correct for the instrument. - I like this test instrument long leads can test at rear of vehicle without additional add on, polarity verification is a great addition, at the touch of a switch. Recommend this for working on any vehicle, saves time and user friendly. ## Features - [WIDELY APPLICATION]: This EM285 circuit tester can be used to test for continuity and polarity of a voltage; check switches, relays, and the on-off of diodes, fuses, and circuits; test for the polarity of electric cables and plugs; track and locate short circuits, and test for bad ground contacts. - [OVERLOAD PROTECTION]: When the current exceeds 8A, the car circuit tester will disconnect the current automatically.
