Wells 1S5022 Multi-Purpose Relay OE Replacement

The Wells 1S5022 is an OE-replacement multi-purpose relay engineered by Wells Vehicle Electronics to meet or exceed original equipment manufacturer specifications for performance and long-term reliability. Designed as a direct-fit replacement, this relay restores proper function to high-amperage vehicle circuits that may have failed or become intermittent due to a worn or damaged relay.

What Does a Multi-Purpose Relay Do?

Multi-purpose relays are responsible for controlling high-amperage electrical circuits throughout the vehicle. Common applications include headlights, fuel pumps, cooling fans, and other power-hungry components. A failed relay can cause a circuit to remain stuck in the on or off position, result in a no-start condition, or impair critical safety systems.

Key Features:

• Engineered to meet or exceed OEM specifications for fit, form, and function
• Lead-free, solderless construction for improved thermal protection and reduced arcing
• Low heat generation design to maximize service life and reduce electrical load
• Built-in thermal shutdown and overvoltage protection guards against abnormal operating conditions
• Circuit protection diodes included where applicable for motor-driven applications
• Sold as a single relay (1 pack)

Installation Tips:

Before installing, visually inspect the complete electrical circuit — including connectors, wiring, and related components — for signs of heat damage or wear. Always confirm the amperage draw of the circuit component is within factory specifications. Reference the OE number on the original relay to verify the correct replacement part.
