Davis Bellew If you are a Subaru owner or enthusiast, you may have heard discussions on whether Subaru vehicles are negative or positive grounded. Grounding is a critical aspect of the electrical system in any vehicle, and it can significantly impact the vehicle’s electrical performance. In this article, we will dive deeper into the topic and explore whether Subaru vehicles are negative or positive grounded.
Key Takeaways
Before we delve deeper into whether Subaru vehicles are negative or positive grounded, here are some key takeaways you should keep in mind:
- Grounding is a critical aspect of the electrical system in any vehicle, and it can significantly impact the vehicle’s electrical performance.
- Negative grounding is the most common type of grounding in modern vehicles.
- Positive grounding is an outdated technology that was common in older vehicles.
- Subaru vehicles are negative grounded, like most modern vehicles.
Now that we have covered the key takeaways let’s explore the topic in more detail.
Understanding Grounding
Before we dive into whether Subaru vehicles are negative or positive grounded, it’s essential to have a basic understanding of what grounding is and its importance in a vehicle’s electrical system.
Grounding is the process of establishing an electrical connection between a piece of electrical equipment and the earth. In a vehicle, grounding ensures that the electrical components have a proper electrical path to the battery and the alternator. This is essential as it helps prevent damage to the vehicle’s electrical system and ensures proper functioning of electrical components.
There are two types of grounding – negative grounding and positive grounding.
Negative Grounding
Negative grounding is the most common type of grounding used in modern vehicles. In negative grounding, the negative terminal of the battery is connected to the vehicle’s chassis, which is connected to the earth. This means that the current flows from the positive terminal of the battery to the vehicle’s electrical components and back to the negative terminal of the battery through the vehicle’s chassis and the earth.
Positive Grounding
Positive grounding is an outdated technology that was common in older vehicles. In positive grounding, the positive terminal of the battery is connected to the vehicle’s chassis, which is connected to the earth. This means that the current flows from the negative terminal of the battery to the vehicle’s electrical components and back to the positive terminal of the battery through the vehicle’s chassis and the earth.
Positive grounding has some disadvantages compared to negative grounding. For instance, in positive grounding, it is more challenging to protect the vehicle’s electrical components and electronics from voltage spikes and damage. Additionally, positive grounding is more susceptible to corrosion, which can lead to poor electrical performance and increased maintenance costs.
Are Subaru Vehicles Negative or Positive Grounded?
Subaru vehicles are negative grounded, like most modern vehicles. This means that the negative terminal of the battery is connected to the vehicle’s chassis, which is connected to the earth. The current flows from the positive terminal of the battery to the vehicle’s electrical components and back to the negative terminal of the battery through the vehicle’s chassis and the earth.
It’s worth noting that some older Subaru models might be positive grounded. However, this is rare, and most Subaru vehicles produced after the 1960s are negative grounded.
Why Negative Grounding is Better
As we have seen, negative grounding is the most common type of grounding used in modern vehicles. This is because it offers several advantages over positive grounding.
Firstly, negative grounding is more reliable than positive grounding. This is because it is more challenging to protect the vehicle’s electrical components from voltage spikes and damage in positive grounding. Additionally, negative grounding is more resistant to corrosion, which can lead to poor electrical performance and increased maintenance costs in positive grounding.
Secondly, negative grounding is more compatible with modern electrical components and electronics. This is because most modern electrical components and electronics are designed to work with negative grounding.
Lastly, negative grounding is more straightforward and easier to understand than positive grounding. This is because negative grounding follows the conventional flow of current from positive to negative, which is more intuitive and straightforward.
Conclusion
Grounding is a critical aspect of the electrical system in any vehicle, and it can significantly impact the vehicle’s electrical performance. Subaru vehicles are negative grounded, like most modern vehicles. Negative grounding offers several advantages over positive grounding, including improved reliability, compatibility with modern electrical components and electronics, and ease of understanding.
While some older Subaru models might be positive grounded, this is rare, and most Subaru vehicles produced after the 1960s are negative grounded.
If you are a Subaru owner or enthusiast, understanding the grounding system in your vehicle can help you maintain and troubleshoot your vehicle’s electrical system. If you are unsure about your Subaru’s grounding system, consult your owner’s manual or a certified Subaru mechanic.
