How To Use Dorman Circuit Tester


A Dorman circuit tester is a device used to test the electrical circuits in a car or truck. It is a very useful tool for diagnosing and troubleshooting electrical problems in vehicles. It is relatively easy to use and can help you identify the source of an electrical problem quickly and accurately. Here is a step-by-step guide on how to use a Dorman circuit tester.

Step 1: Get Familiar with the Device
Before you begin using the Dorman circuit tester, it is important that you become familiar with the device. It consists of two parts: a probe and a ground clip. The probe is used to probe the circuits and the ground clip is used to connect the device to the vehicle’s chassis or frame. It is important that you understand how the device works before you begin using it.

Step 2: Connect the Device to the Vehicle
The next step is to connect the Dorman circuit tester to the vehicle. To do this, you will need to connect the ground clip to the vehicle’s chassis or frame. This will ensure that the device is properly grounded and that it can provide accurate readings. Once the ground clip is connected, you can then plug the probe into the vehicle’s electrical system.

Step 3: Test the Circuits
Once the device is connected to the vehicle, you can begin testing the circuits. To do this, you will need to use the probe to probe the circuits. When you probe the circuit, you should observe the readings on the device’s display. If the reading is within the specified range, then the circuit is functioning properly. If the reading is outside of the specified range, then the circuit may be malfunctioning.

Step 4: Troubleshoot the Problem
If you find that the circuit is malfunctioning, then you will need to troubleshoot the problem. To do this, you will need to use the Dorman circuit tester to test the other components of the circuit. This will help you identify the source of the problem. Once you have identified the source of the problem, you can then take the necessary steps to fix it.

Step 5: Disconnect the Device
Once you have identified and fixed the problem, you can then disconnect the Dorman circuit tester from the vehicle. To do this, you will need to unplug the probe and disconnect the ground clip. Make sure that the device is properly disconnected before you move on to the next vehicle.

Using a Dorman circuit tester is a great way to quickly and accurately diagnose and troubleshoot electrical problems in vehicles. By following the steps outlined above, you should be able to use the device with ease. Remember to always be safe when working with electrical systems and always follow the manufacturer’s instructions.
