A 12-volt battery ignition system has several advantages over a 6-volt system. The most notable advantage is the increased power output. A 12-volt system can produce nearly twice the voltage of a 6-volt system, which allows for a stronger spark at the spark plugs. This stronger spark can lead to improved combustion of the fuel in the engine, resulting in better performance and fuel efficiency.
Another advantage of a 12-volt system is that it can handle more electrical loads. Modern vehicles are equipped with a wide variety of electrical components and accessories, such as lights, radio, and power windows. These components often require more power than a 6-volt system can provide, making a 12-volt system a better choice for these types of vehicles.
In addition, 12-volt systems are more common and easier to find replacement parts for. This means that if a component of the ignition system needs to be repaired or replaced, it will likely be easier to find a suitable replacement part. This can save time and money in the long run.
Another advantage is that a 12-volt system can use smaller gauge wiring than a 6-volt system, which can reduce the weight of the vehicle, and make the wiring more efficient.
Lastly, 12-volt battery ignition systems are more efficient in generating power for starter motors and alternators, which are essential components for starting an engine and keeping the battery charged.
All these advantages make a 12-volt battery ignition system a more suitable choice for modern vehicles over a 6-volt system.
