Replacing the stock ignition coil with an aftermarket coil can boost your bike’s performance. One of the most popular choices is the Dyna coil. However, installing it can be challenging if you don’t have a wiring diagram. In this article, we’ll discuss everything you need to know about the Dyna coil wiring diagram.
What is a Dyna Coil?
Dyna is a leading manufacturer of high-performance ignition systems for motorcycles. Their coils are designed to deliver more spark energy to the plugs, which can translate to better throttle response, improved power, and increased fuel efficiency. Dyna coils are available in different configurations and sizes, but they all share the same principle of operation: converting the low-voltage DC power from the battery to high-voltage AC power to fire the spark plugs.
Types of Dyna Coils
Dyna coils come in three types: single output, dual output, and mini coils. The single output coil is the most common type, and it’s suitable for most stock and mildly modified bikes. The dual output coil has twice the spark energy of the single coil, and it’s ideal for high-performance and racing applications. The mini coils are small and lightweight, and they’re designed for bikes with limited space.
Dyna Coil Specifications
The Dyna coil specifications vary depending on the model and type, but here are some general parameters:
| Parameter | Single Coil | Dual Coil | Mini Coil |
|---|---|---|---|
| Primary Resistance | 0.5-5.0 ohms | 0.2-1.5 ohms | 0.5-3.0 ohms |
| Secondary Resistance | 6,000-25,000 ohms | 12,000-45,000 ohms | 6,000-25,000 ohms |
| Spark Energy | 35-45 mJ | 80-100 mJ | 35-45 mJ |
| Peak Current | 1.5-2.2 A | 3.0-4.5 A | 1.5-2.2 A |
Dyna Coil Wiring Diagram
The Dyna coil wiring diagram is slightly different from the stock coil wiring, but it’s not complicated. Here’s a step-by-step guide to wiring a Dyna coil:
Step 1: Disconnect the Battery
Before you start wiring the Dyna coil, make sure the battery is disconnected to avoid short circuits and other electrical hazards.
Step 2: Remove the Stock Coil
If you’re replacing the stock coil with the Dyna coil, you’ll need to remove the stock coil from the bike. Depending on the bike model, you may need to remove the tank, seat, or side covers to access the coil.
Step 3: Mount the Dyna Coil
The Dyna coil may come with a bracket or mounting plate that you can attach to the bike’s frame or other suitable location. Make sure the coil is securely mounted and won’t move or vibrate while riding.
Step 4: Wire the Dyna Coil
The Dyna coil has two primary terminals and two secondary terminals. The primary terminals are marked “+” and “-“, and the secondary terminals are marked “1” and “4”. Here’s how to wire the Dyna coil:
- Connect the “+” terminal to the ignition switch or power source.
- Connect the “-” terminal to the ignition module or ground.
- Connect the “1” terminal to the spark plug on the left side of the engine.
- Connect the “4” terminal to the spark plug on the right side of the engine.
- If you have a dual output coil, connect the two “+” terminals together and the two “-” terminals together.
- If you have a mini coil, the wiring may vary depending on the bike model and configuration.
Dyna Coil FAQ
1. What’s the difference between a single output and a dual output Dyna coil?
The main difference between a single output and a dual output Dyna coil is the spark energy. A dual coil can produce twice the spark energy of a single coil, which can provide better performance and combustion. However, a dual coil may require a higher current and voltage from the electrical system, and may not be suitable for all bikes.
2. Can I use a Dyna coil with a stock ignition module?
Yes, you can use a Dyna coil with a stock ignition module, but you may not get the full benefits of the coil. The stock module may not be able to deliver enough current and voltage to fully activate the Dyna coil, or may not be optimized for the coil’s characteristics. To fully capitalize on the Dyna coil’s potential, you may need to upgrade the ignition module or use a Dyna ignition system.
3. Can I wire the Dyna coil in reverse polarity?
No, you should wire the Dyna coil in the correct polarity as indicated by the markings on the terminals. Wiring the coil in reverse polarity may damage the coil or the electrical system, and may cause poor performance or misfires.
4. Can I use a mini coil on a big bike?
Yes, you can use a mini coil on a big bike, but you need to make sure it’s suitable for your bike’s configuration and ignition requirements. Mini coils are designed for bikes with limited space, but they may not have the same spark energy or current capacity as larger coils. Before using a mini coil, check the specifications and consult with a Dyna specialist or a qualified mechanic.
5. Can I install a Dyna coil myself?
Yes, you can install a Dyna coil yourself if you have basic electrical skills and tools. However, if you’re not familiar with wiring or troubleshooting electrical systems, it may be safer and more cost-effective to have a professional mechanic or Dyna dealer install the coil for you. Improper wiring or installation may cause damage to the coil, the bike, or yourself.
Conclusion
The Dyna coil is a popular aftermarket ignition component that can enhance your bike’s performance and reliability. By following the correct wiring diagram and installation procedures, you can enjoy the benefits of the Dyna coil without compromising your bike’s electrical system or safety. If you have any questions or concerns about the Dyna coil or ignition systems, don’t hesitate to seek advice from experts or reputable sources.
