An electrical short circuit could be causing your car to act up. Short circuits are electrical faults that create a sudden flow of electricity through an incorrect pathway. Sparks, heat, and even fire can be created due to a short circuit. Use the guide below to find and fix an electrical short.
How To Find An Electrical Short In Your Car
While short circuits can be quite the hassle, this is an issue that can be identified as a DIY task as long as you have some expertise with car electrical systems. Use the steps below to both find and fix a short circuit.
Step 1. Identify Symptoms Of The Short Circuit
- The first step of this process involves properly identifying the symptoms of the short circuit.
- There are some common signs to look for, such as lights dimming/flickering and odd electrical noises.
- If the car turns over slowly or refuses to start, this could indicate an electrical short.
Step 2. Check Fuses And Wiring
- Check the fuses and wiring inside your car.
- The fuse box will be located under your car’s hood.
- If any fuses are blown, this could indicate a short.
- You can also check the wiring for any obvious signs of damage or corrosion.
Step 3. Test Electrical Components
- Next, test the car’s electrical components one by one.
- Use a voltage meter to measure the current running through each component accurately.
- You should be able to determine exactly which component is leading to the short circuit.
Step 4. Utilize Wire Testing Tools
- Some wire testing tools can be used to locate a short circuit.
- One such tool is a continuity tester.
- This tool allows you to test whether two points in a circuit are truly connected.
- You can use an ohmmeter to test the circuit’s resistance.
- A multimeter can also be used during this step, as well.
- This tool measures the current, voltage, and resistance within a circuit.
- The readings of your multimeter should allow you to locate exactly where the short is coming from.
Step 5. Replace Damaged Components
- Once the short is located, it’s time to fix the issue.
- There are a few steps that must be followed to complete the fix.
- If your car’s wiring is damaged, it may be time for a replacement.
- Always reference the owner’s manual prior to replacing any parts within your car.
