Apart from the earth and positive wires, you also need to pay Attention to the wires that connect the generator to a control panel or to your van. These wires carry the main output from the generator and typically include a 12-volt output, as well as a 240-volt output. The 12-volt output is rectified from the generator's AC output and can be directly connected to devices. The 240-volt output is used for powering appliances and is connected through a breaker.
Components of the Generator
Now that we have a basic understanding of the wiring, let's explore the different components of the generator.
12 Volt Output
The generator produces a 12-volt DC output through rectification. This 12-volt output comes directly from the generator assembly and can be used to power devices such as lights or charge batteries. It is important to note that this output is already rectified and ready for use.
240 Volt Output
In addition to the 12-volt output, the generator also provides a 240-volt output for powering larger appliances. This output consists of live, neutral, and earth wires. It does not require any rectification and can be directly connected to the output sockets on the generator assembly.
Ignition Coil
The ignition coil is responsible for stopping the engine. By grounding the wire connected to the ignition coil, the engine is effectively disabled. When the wire is not touching the ground, the engine runs smoothly, and as soon as it makes contact, the engine stops. This provides a simple and effective way to control the engine.
Oil Alert Switch
The oil alert switch is a safety feature that monitors the oil level in the engine. When the oil level drops, the switch is grounded, effectively connecting it to the engine's ground and killing the engine. This ensures that the engine does not run without sufficient lubrication.
Frame and Mounting
Once you have a good understanding of the wiring and components of the generator, it's time to consider the frame and mounting options. The frame plays a crucial role in holding the generator securely in place and protecting it from external factors. Let's discuss the key aspects of the frame and mounting process.
Choosing a Suitable Frame
When choosing a frame, it is important to consider the weight and durability. Opt for a frame that is sturdy enough to withstand the vibrations and shocks while the van is in motion. Thin tubings may not be suitable for this purpose, so it is recommended to use angle iron frames that can be securely fitted under the van.
Mounting the Generator Under the Van
Mounting the generator under the van allows for easy access and protects it from the elements. Position the generator in an area that minimizes the risk of water exposure, such as near the rear axle or the front section of the chassis. Ensure that the generator is securely attached to the frame and does not interfere with any other essential components.
Using an RCD Box for Safety
To ensure safety, it is recommended to use an RCD (Residual Current Device) box. This box acts as a junction box and incorporates breakers for the 240-volt and 12-volt lines. It also includes an MCB (Miniature Circuit Breaker) for protecting the generator's power supply. By using an RCD box, you can efficiently control the power flow and easily disconnect the generator when needed.
Wiring and Connections
Now that the generator is securely mounted, let's move on to wiring and making the necessary connections. This step is crucial to ensure that the generator is properly integrated into your van's electrical system. Let's break down the key aspects of wiring and connections.
Junction Box for 240 and 12 Volt
In the junction box, you will connect the 240-volt and 12-volt outputs of the generator. This box acts as a central point for connecting the generator's power supply to the van's electrical system. Make sure to use appropriate connectors and secure all the connections properly to prevent any loose or faulty wiring.
Connecting the Battery
The battery is a vital component of the generator setup. Connect the positive wire from the generator to the positive terminal of the battery, and the earth wire should be securely bolted to the battery's negative terminal. These connections ensure that the battery is properly charged and can supply power when needed.
Kill Switch Wires
The kill switch wires provide a convenient way to start and stop the engine. The oil alert switch wire connects to the oil alert switch in the engine and is grounded when the oil level drops, effectively killing the engine. These wires are connected to the control panel in the van, allowing you to start and stop the engine with a simple switch.
Charging System
The charging system of the generator ensures that the battery is kept charged and ready for use. Let's explore how it works and how to set it up.
Understanding the Generation Coil
