Pit bikes are quite popular nowadays among riders around the world. These are small, powerful motorcycles that can be used for racing or off-road riding. One of the most important aspects of pit bikes is the wiring system. A proper wiring diagram is essential to ensure that the bike runs smoothly and efficiently. This article will explain the wiring system for pit bikes with a battery.
Basic components of a pit bike electrical system
Before we get into the wiring diagram, let’s take a look at the basic components of a pit bike electrical system:
- Battery
- Stator
- Regulator/Rectifier
- CDI (Capacitor Discharge Ignition)
- Coil
- Spark plug
- Ignition switch
- Wiring harness
Battery
The battery is the heart of the electrical system. It stores electrical energy that is used to power the bike’s electrical system. Pit bikes typically use a 12-volt battery, which is rechargeable.
When the bike is running, the stator generates electrical power, which is used to recharge the battery. When the bike is not running, the battery provides power to the electrical system.
Stator
The stator is a component that generates electrical power. It is located on the engine and is connected to the flywheel. As the flywheel rotates, the stator generates an electrical charge, which is used to power the electrical system and recharge the battery.
Regulator/Rectifier
The regulator/rectifier is a component that regulates the voltage produced by the stator and converts it into a direct current (DC) that can be used by the electrical system. It prevents the battery from overcharging and ensures that the electrical system receives a consistent voltage.
CDI (Capacitor Discharge Ignition)
The CDI is a component that controls the ignition system. It uses a capacitor to store electrical energy, which is released in a high-voltage pulse to the coil. This pulse creates a spark at the spark plug, which ignites the fuel in the engine.
Coil
The coil is a component that transforms the low-voltage electrical energy from the CDI into a high-voltage pulse that can ignite the fuel in the engine. It is connected to the spark plug by a high-tension lead.
Spark plug
The spark plug is a component that creates a spark to ignite the fuel in the engine. It is connected to the coil by a high-tension lead and is located in the engine’s cylinder head.
Ignition switch
The ignition switch is a component that controls the flow of electrical power from the battery to the electrical system. It is usually located on the handlebars and can be turned on or off to start or stop the engine.
Wiring harness
The wiring harness is a collection of wires that connect all the electrical components of the bike. It routes electrical power from the battery to the various components and ensures that the electrical system operates correctly.
