5 Best Circuit Tester in 2018
Despite the complex electronics of today’s cars, many glitches can still be solved by a simple test lamp. While most DIY mechanics will shy away from tackling problems involving sensors and the like, many will take on a dodgy light, or kit such as heaters, wipers or switches. And for a quick, easy way of tracking down these faults or a blown fuse, look no further than a test lamp. Basic circuit testers are little more than a screwdriver with a lead and bulb in the handle, and are often considered to be a poor man’s multimeter, but recent units are more advanced in their design. Many can show the voltage and polarity at the probe point – much more useful than just knowing whether a feed is live or not. They can also power up suspect components – such as bulbs or motors – simply by placing the probe on the terminal, connecting the earth lead to the casing and pressing a button. Proving whether components work or not often makes it much easier to trace electrical gremlins. Here are top 5 best circuit tester for you.

Also referred to as a test light, the circuit tester is a simple device which indicates whether or not a particular electrical circuit is complete. This type of tester is helpful in locating blown fuses, as well as determining if a battery voltage or ground signal is being supplied to an electrical component. An unpowered circuit tester requires voltage from the vehicle to illuminate a bulb which is integrated into the handle of the device. One pole of the unpowered circuit tester is grounded, while the other end probes for voltage, or vice versa. When a complete circuit is detected, the bulb illuminates. An incomplete circuit will not illuminate the bulb; making you aware that this circuit requires attention. A powered circuit tester, as the name implies, is internally powered and/or grounded depending upon the task selected. The powered circuit tester is typically battery powered, with various visual and audio indicators. It detects complete and incomplete circuits, as well. The difference between the powered and unpowered circuit tester is that the powered circuit tester need only contact one point in the circuit to determine its validity. Every car owner should purchase and own a circuit tester to be aware of the condition of the vehicle.
