Automotive testers for checking electrical circuits

To ensure safety and proper operation, any machine must operate by the regulatory parameters specified by the manufacturer. There are car testers who only visit auto repair shops sometimes. It allows you to check many technical indicators of the car independently.

Varieties of car testers

Currently, automotive electrical testers are represented by a wide range. It allows you to check many vital indicators of your car. We will look at the most common automotive testers.

Tire tread tester

This automotive tester provides the ability to determine the tread depth and wear level of the brake pads. Such a check is necessary for their timely replacement. Its dimensions are compact, and the measurement accuracy is 0.01mm.

Diagnostic battery tester

Such a tester for car allows you to determine the functionality of the battery: find out the degree of charge and performance when starting the engine, and also provide advice in case of a battery reset. It has an LED display, reverse connection protection, and will not rust.

Voltage circuit tester

The automotive circuit tester checks power ground and detects short circuits and open wiring. If the tester pen lights up, there is a circuit malfunction. With its help, headlights, a course for direction indicators, breakage of sockets, fuses, and various connections are checked.

Automotive system diagnostic tester

This circuit tester automotive is capable of performing various tests, such as:

●     power supply;

●     integrity and activation of circuit components;

●     availability of grounding;

●     polarity.

Such a circuit tester car provides a straightforward reading of voltage, current, and resistance, and a built-in flashlight allows you to work in the dark.

Car pen for checking candles

This electrical tester for car checks the situation of engine spark plugs. These candles are necessary to ignite the fuel – the air mixture in the cylinders of gasoline engines. Such a tester will quickly be able to determine the charge level of the candles.

Automotive relay tester

Automotive electrical testers also include checking a relay designed to close and open an electrical circuit on a signal. Connecting such current consumers as a fan, radiator, and glass heating is necessary. Such a tester for a car is suitable for relays with a resistance of more than 20 ohms. It has indicators red and green, indicating the operation of the relay is bad or average, respectively.

Digital DC resistance ammeter

These automotive electrical testing tools measure fuse current. The ammeter is battery-operated, has a rubberized coating, and does not slip in your hand. The results are displayed on the LCD, controlled by just one button, so they are straightforward.

OBD II Fault Detection Tester

OBD II is an adapter that reads the manufacturer's error codes and displays their meaning. Therefore, the failure of this indicator can have a very negative effect on the engine's operation. Such automotive circuit testers make it easy to detect a malfunction in the machine and take measures to eliminate it.

Where can you find such devices?

The indicated auto electrical testers of cars and many others are presented with detailed characteristics on the All Automotive Accessories website. A wide range will allow you to choose the necessary auto tester.

Having an electrical tester for cars on hand, you can independently monitor essential indicators of the electrical circuits of a vehicle.
