The Unconventional Guide To Finding An Electrical Short Circuit In Your Car

The Unconventional Guide To Finding An Electrical Short Circuit In Your Car

There’s nothing quite like knowing your car is on fire. Okay, maybe that’s a bit of an exaggeration. Still, if you’ve ever had the unfortunate experience of seeing your car battery smoke or hearing strange noises arising coming from under the hood, you know it’s not a good feeling.

In this blog post by the The Key Online – Tulsa, OK, we’ll walk you through the process of finding and fixing an electrical short in your car.

Using a Multi-meter

While there are several ways to approach this problem, we’ll focus on the most common and straightforward method: finding the short using a multi-meter. A multi-meter is an essential tool for any do-it-yourselfer, and it’s relatively cheap and easy to use.

If you’re not familiar with how to use a multi-meter, don’t worry – we’ll walk you through it step by step.


First, you’ll need to set the multi-meter to the “resistance” or “ohms” setting.


Next, you’ll need to disconnect the battery and unplug accessories connected to the multi-meter.


When the battery is disconnected, you’ll need to locate the fuse box. Then, you’ll need to identify the affected circuit. Locate the fuse box under the hood. However, you can find it under the dashboard as well.


Next, find a point where you can access the wire. You can remove a connector or splice it into the wire.


After that, you must access the wire; you’ll need to attach the multi-meter’s probes to the exposed wires. There is an electrical short when there is continuity between the two wires.


If you’re unable to find a point where you can access the wire, you’ll need to remove the entire panel and look for damage.


Once you’ve located and repaired the electrical short, it’s essential to test your work. You can do this by reconnecting the panel and turning on the car.

If everything is working correctly, you should be able to drive your car without problems. If there are still issues, you’ll need to track down the source of the electrical short.

This process can be time-consuming, but it’s the best way to ensure that your car runs properly. By taking the time to troubleshoot the circuit, you can avoid costly repairs down the road.

Be prepared when troubleshooting a car’s electrical system. You must have the right tools and know how to use them before you start working on your car. Here are a few tips:

  • If a fuse blows when you’re trying to troubleshoot an electrical system, it’s a good idea to check for loose wires. If you find any, make sure to tighten them or replace them if they’re damaged.
  • Another thing to look for is corrosion or damage. Water getting into the system causes it, so make sure all connections are dry and free of rust.
  • Once you’ve checked for loose wires and corrosion, you can start using a short finder. This tool will help you locate the source of the problem to fix it.

Locating an electrical short in a car is not just important for your current car, but this knowledge will also come in handy when you purchase a used car as you will be able to check it for electric issues before deciding to invest in it.
