Understanding the Viair Relay Wiring Diagram is crucial for anyone looking to correctly install and operate an air compressor system. This diagram acts as a blueprint, guiding you through the electrical connections needed to power your Viair compressor safely and efficiently. A properly understood Viair Relay Wiring Diagram ensures your air system performs as intended, preventing potential electrical issues and extending the life of your equipment.
What is a Viair Relay Wiring Diagram and How is it Used?
At its core, a Viair Relay Wiring Diagram is a schematic that illustrates how the electrical components of your Viair air system should be connected. Relays are essentially electrically operated switches. They are used to control high-current devices, like air compressors, using a low-current signal from a switch. This is important because directly powering a high-amperage compressor through a simple dash switch could overload the switch and wiring, leading to damage or a fire hazard. The relay acts as an intermediary, allowing a smaller, safer circuit to control the larger circuit that powers the compressor motor.
The diagram will typically show the flow of power from your vehicle's battery, through various protective components, to the relay, and finally to the compressor. Key elements you’ll find on a Viair Relay Wiring Diagram include:
- The battery positive (+) and negative (-) terminals.
- A fuse or circuit breaker to protect the system from overcurrent.
- The relay itself, with its terminals clearly labeled (e.g., 85, 86, 87, 30).
- The switch that will activate the compressor (e.g., a toggle switch, pressure switch).
- The air compressor's motor.
Here's a simplified look at how the connections generally work:
| Relay Terminal | Purpose |
|---|---|
| 85 & 86 | Coil terminals. Connected to the control switch and ground/battery for the low-current circuit. |
| 30 | Battery (+) input for the high-current circuit. |
| 87 | Output terminal. Connects to the positive (+) terminal of the air compressor. |
The importance of following the Viair Relay Wiring Diagram accurately cannot be overstated . Incorrect wiring can lead to component failure, the compressor not engaging, or even dangerous electrical shorts.
When you're ready to tackle the installation, the specific Viair Relay Wiring Diagram that came with your compressor kit is your most valuable guide. Refer to it diligently for the precise wire colors, terminal assignments, and suggested fuse ratings appropriate for your particular Viair model. This ensures a safe and functional installation every time.
