Why I Prefer a 12 Volt Coil With Internal Resistor
As a car enthusiast, I have spent countless hours working on and modifying my vehicles. One crucial component that I have learned to appreciate is the ignition coil. It plays a crucial role in starting and running the engine, making it one of the most critical parts of a vehicle’s ignition system.
In my experience, using a 12-volt coil with an internal resistor has proven to be the best option. This type of coil has a built-in resistance that limits the amount of current flowing through it. This feature is essential for several reasons.
Firstly, it protects the coil from overheating and burning out. Without an internal resistor, the coil would receive full battery voltage, which could cause it to overheat and fail prematurely. This would not only be costly but also frustrating as it can leave you stranded on the side of the road.
Secondly, using a 12-volt coil with an internal resistor can extend the life of other ignition components such as points and condensers. The restricted current flow reduces arcing at these parts, preventing them from wearing out quickly.
Another advantage of using this type of coil is that it eliminates the need for an external ballast resistor
My Buying Guide on ’12 Volt Coil With Internal Resistor’
Are you in the market for a 12 volt coil with internal resistor? As a car enthusiast and mechanic, I understand the importance of choosing the right coil for your vehicle. In this buying guide, I will walk you through the necessary information to consider before making your purchase.
Understanding Coils and Resistors
Before diving into the specifics of a 12 volt coil with internal resistor, it is important to understand what these components do. A coil is an essential part of a vehicle’s ignition system that converts low voltage from the battery into high voltage needed to ignite the fuel in the engine. On the other hand, a resistor is used to limit and control the flow of electricity in a circuit.
The Importance of an Internal Resistor
An internal resistor inside a 12 volt coil is designed to reduce electromagnetic interference (EMI) caused by high voltage ignition systems. This interference can disrupt electronic components in modern vehicles, leading to malfunctions or even damage. Therefore, having an internal resistor in your coil is crucial for proper functioning of your vehicle’s electronic systems.
Compatibility
When purchasing a 12 volt coil with internal resistor, it is important to ensure compatibility with your vehicle’s make and model. Some coils are designed specifically for certain vehicles, while others have universal compatibility. It is important to check the specifications or consult with a mechanic before making your purchase.
Quality and Durability
Investing in a high-quality coil with an internal resistor will save you from frequent replacements and repairs. Look for brands that are known for their durability and have positive reviews from other customers. It is also important to check the warranty offered by the manufacturer, as this can give you peace of mind knowing that you are covered in case of any defects or issues.
Price
The price of 12 volt coils with internal resistors can vary depending on brand, quality, and compatibility. While it may be tempting to opt for cheaper options, it is important to consider long-term costs and potential damages that may arise from using low-quality coils. It is recommended to invest in a high-quality coil even if it means spending a little more upfront.
Final Thoughts
In conclusion, when purchasing a 12 volt coil with internal resistor, it is crucial to consider its compatibility with your vehicle, quality and durability, as well as its importance in reducing EMI interference. Investing in a high-quality coil may cost more initially but will save you from potential damages and frequent replacements in the long run.
