AWBLIN Wire Tracer Automotive Electrical Open & Short Finder Circuit Tester Wire Breaker Finder Fault Probe Cable Tracker Electrical DC 6-42V

MULTIFUNCTIONAL WIRE TRACER: This multi-functional open & short finder circuit tester can easily locating the circuit breaker point, open connections, broken wires, conduction, current leaks with tone change, even trace wire/cable without damaging the insulation. This is a convenient and efficient circuit tracer kit for DIYers, electricians, and technicians, to simply and quickly judge the continuity of the cables/wire and diagnose the breaker point.
SOUND & LIGHT SIGNAL INDICATION:The wire tracer electrical is equipped with a transmitter and a receiver, which clearly display the test status through sound and LED lights. At the same time, the battery level has a low battery indicator. When the low battery flashing red light indicates that you need to replace the battery. Unlike similar products on the market, you no longer have to be disturbed by noise or affected by battery power. This feature enables you to test more accurately and efficiently without any worries.
LOCATING BREAKER POINT: When the transmitter is turned on downward, if the GREEN light flashes, it indicates that there is an open circuit. The receiver has three function modes representing different intensities that can be adjusted as needed. In areas without an open circuit, the receiver's signal light is full and accompanied by a rapid beeping sound. At the breakpoints, the signal lights and beeps will weaken or even disappear.
CHECKING SHORT CIRCUIT: When the transmitter is turned on downward, if the RED light flashes, it indicates that there is a short circuit in the circuit. At this point, the red signal light on the receiver is full and accompanied by a rapid beeping sound, indicating a short circuit. In areas without a short circuit, the receiver has no signal, and both the LED light and the beeping sound disappear.
CONTINUITY FUNCTION: Push the transmitter switch upwards to the CONT mode, and attach the red and black clips to both ends of the wire under test respectively. If the wires are in good condition, the green light will come on. If it doesn't light up, it indicates that the wire is faulty.
