Key features

• •1.【Electrical Tester for Open Circuit Testing】The Circuit Breaker Finder can check whether there is a short circuit in the car circuit through the LED test light, and this power probe can test for continuity with the assistance of its auxiliary ground lead. Check switches, relays and the on-off of diodes, fuses, spark plugs and circuits. (The green light is on means the circuit is in a continuous state; the green light is off, it means the circuit is open).
• •2.【Diode Test & Polarity Tester】When the polarity of the circuit under test is unknown, this power probe can help you quickly identify positive and negative polarity of electric cables and plugs(Red light indicates positive polarity and green light indicates negative polarity),and quickly test the circuit diode group and determine its open circuit and continuity.
• •3.【Voltage Tester Grounding Test】The continuity tester can test whether there is a large current through the component and whether the negative pole is well grounded to prevent circuit damage caused by excessive voltage. (The green light is on and a beeping sound indicates that the grounding is good; the green light is on and there is no buzzing, it indicates that the grounding is poor.)
• •4.【Electrical Tools with Overload Protection & DC Voltage Test】In the case of overload or load current, the circuit will be automatically disconnected, protected and buzzed to reduce unnecessary losses.The tester electric is widely applicable to all 6V-24V DC vehicle electrical systems.
• •5.【Easy Operation of Circuit Breaker Finder】After a simple hook-up of the Electric Tester to the vehicle's battery, automotive technician can conduct a positive or negative battery current to the tip by rocking the power switch forward or backward. Note: This power probe do not use on AC voltage.
