The Basics – Car electrical diagnostics can be a challenging task, especially if you are not familiar with the electrical systems of a vehicle.

It requires a good understanding of how the electrical systems work and the ability to use specialized diagnostic tools to identify and troubleshoot problems.

Common reasons why automotive and car electrical diagnostics can be difficult:

  1. Complexity: Modern cars (and upgraded older vehicles) are equipped with complex electrical systems that include multiple sensors, control modules, and other electronic components. These systems can be difficult to understand and diagnose, especially if you are not familiar with the technology. Projects performed by previous owners often make this process even more difficult.
  2. Interconnected systems: Many of the car’s systems are interconnected and a problem in one system can affect the performance of other systems. For example, an issue with the air conditioning system may be caused by a problem with the electrical system or a sensor.
  3. Advanced diagnostic tools: Car electrical diagnostics often require specialized diagnostic tools such as scanners and multimeters, plus the EXPERIENCE AND KNOWLEDGE TO USE THEM. These tools can be expensive and require training to use them correctly.
  4. Access to information: Car electrical diagnostics require access to service information, wiring diagrams and troubleshooting procedures. This information can be difficult to find, especially for older or rare vehicles.
  5. Experience: Car electrical diagnostics require a good understanding of the electrical systems, experience in using diagnostic tools, and the ability to troubleshoot and solve problems. Without the proper knowledge and experience, it can be difficult to correctly diagnose and repair car electrical problems. Many issues require fundamental electrical diagnostic knowledge that goes beyond the realm of the workshop manuals or processes for a different specific fix or repair.

Wiring Harness Repair & Replacement

One of the most common items customers contact us about is the repair and replacement of their vehicle’s primary wiring harness. While repair is sometimes justified (perhaps a small area was impacted by an issue, water intrusion, etc) there are also many times when a complete replacement of the wiring harness isn’t only recommended, but required.

Safely installing, securing, and verifying the function of these upgrades and installations is a tedious task that has immense implications on your vehicle’s reliability and safety if not done correctly. One of the most common complaints we hear about is how other shops or mechanics don’t have the experience or understanding required to perform electrical work and repairs. At Hardcore Hot Rods, our experienced staff of classic car electrical technicians go the extra mile to ensure that everything is safe, secure, protected, and checks out perfectly on a test drive.

Although car electrical diagnostics can be a challenging task, having a shop with the proper knowledge and experience is critical to efficiently and effectively resolving any issues you may have. Not only do we have the necessary tools and experience to quickly identify and fix the problem, but the odds are that we’ve probably seen it before and are familiar (which can be highly uncommon for mechanics which mostly operate on newer generation vehicles.)
