Modern vehicles are heavily reliant on complex electrical systems. When these systems malfunction, it can lead to a variety of frustrating and potentially dangerous issues. While you might be tempted to call a tow truck at the first sign of electrical trouble, there’s a chance you can get back on the road with the help of an AA diagnostic van. But can these mobile mechanics really handle electrical faults?
AA Diagnostic Van Diagnosing an Electrical Fault
Understanding Electrical Faults in Cars
Automotive electrical faults can manifest in a wide array of symptoms, ranging from minor inconveniences to major drivability problems. Some common signs of electrical trouble include:
- Dashboard warning lights: The check engine light, battery light, or other warning lights on your dashboard can indicate an electrical problem.
- Starting issues: Difficulty starting the engine, clicking sounds when turning the key, or a dead battery could all point to an electrical fault.
- Dimming or flickering lights: Fluctuations in the intensity of headlights, interior lights, or dashboard lights might suggest a problem with the charging system or wiring.
- Malfunctioning accessories: Issues with power windows, radio, air conditioning, or other electrical components can also be caused by electrical faults.
What Can an AA Diagnostic Van Do?
AA diagnostic vans are essentially mobile workshops equipped with a range of tools and technologies designed to diagnose and, in some cases, repair vehicle problems. When it comes to electrical faults, these vans are particularly adept at:
- Reading and interpreting fault codes: Using advanced diagnostic equipment, AA technicians can interface with your car’s onboard computer (ECU) to retrieve and decipher diagnostic trouble codes (DTCs). These codes provide valuable clues about the nature and location of electrical faults.
- Testing battery and charging system health: AA technicians can test your car battery’s voltage and perform load tests to assess its health. They can also diagnose problems with the alternator, voltage regulator, and other charging system components.
- Inspecting wiring and connections: Loose connections, damaged wires, and corroded terminals are common culprits behind electrical gremlins. AA technicians are trained to identify and rectify these issues.
Limitations of AA Diagnostic Vans
While AA diagnostic vans can effectively diagnose and address many electrical faults, they do have their limitations. Here are a few factors that might prevent an AA technician from fully resolving your car’s electrical problem:
- Complexity of the fault: Some electrical issues, such as problems within the ECU itself or intricate wiring harness faults, may require specialized knowledge and equipment beyond the scope of an AA diagnostic van.
- Availability of parts: If the fault requires replacing a specific electrical component, the AA technician may not have the necessary part on hand. This could lead to delays in the repair process.
- Accessibility issues: Certain electrical components might be located in hard-to-reach areas of the vehicle, making it difficult for the AA technician to perform repairs on-site.
When to Call an AA Diagnostic Van for Electrical Faults
Calling an AA diagnostic van can be a smart move if:
- You’re experiencing intermittent electrical problems: If the issue comes and goes, it can be challenging to diagnose. An AA technician can often pinpoint the root cause more effectively than you could on your own.
- You’re stranded on the side of the road: In this situation, an AA diagnostic van can provide on-site assistance and potentially get you back on your way quickly.
- You want a preliminary diagnosis before going to a garage: An AA inspection can save you time and money by providing a clear understanding of the problem before you take your car to a more expensive repair shop.

FAQs about AA Diagnostic Vans and Electrical Faults
Can an AA van fix my car’s electrical problems on the spot?
In many cases, yes. AA technicians are trained to handle a variety of common electrical repairs, such as replacing batteries, alternators, and faulty wiring. However, more complex issues might require your car to be towed to a specialist garage.
How much does it cost to have an AA diagnostic van come out?
The cost of an AA call-out varies depending on your location and membership status. You can typically find pricing information on the AA website or by contacting them directly.
What if the AA diagnostic van can’t fix my electrical problem?
If the AA technician determines that the fault is beyond their scope of expertise or requires specialized parts or equipment, they will advise you on the best course of action. This might involve recommending a specific garage or arranging for your car to be towed.
Do I need to be an AA member to use their diagnostic services?
While AA membership often comes with benefits like discounted call-out fees, you can still use their diagnostic services even if you’re not a member.
