KanSmart 12V 250A Winch Solenoid Relay Contactor for ATV/UTV — 3,000–5,000 lb fit, sealed powder-coated build

KanSmart 12V 250A winch solenoid relay is a weather-resistant replacement contactor designed to control power flow for ATV and UTV winches rated roughly 3,000–5,000 lbs.

When a winch loses response or the original relay corrodes, this KanSmart solenoid contactor provides a durable, plug-in style option that fits many popular winch brands. Built with a powder-coated steel body and sealed terminals, it aims to restore reliable in/out control while protecting the vehicle's electrical system. Below you'll find common buyer questions answered, practical installation notes, and a quick guide to compatibility.

How does this relay restore winch operation?

The relay acts as a high-current switch: a low-voltage command from the winch switch activates the solenoid, which then routes battery power to the winch motor. Replacing a failed or stuck contactor with this unit should re-enable normal spool-in and spool-out functions while reducing arcing at the original switch.

• Direct replacement for many 12V winch systems that used similar contactor part numbers.
• Handles up to 250 amps continuous load for typical 3,000–5,000 lb winches.
• Sealed design reduces corrosion and keeps electrical connections cleaner.
• Comes with protective caps for exposed posts to prevent shorting.

Which vehicles and winches does it fit?

This KanSmart contactor is made to be a cross-reference replacement for several OEM and aftermarket winch solenoids. It matches common reference numbers used by brands and fits many ATV and UTV winches from mainstream manufacturers when their original relay fails.

• Compatible references include WARN part equivalents and other common relay codes.
• Fits many Polaris, Honda, KFI, Ramsey, Superwinch, Mile Marker, Smittybilt systems and more.
• Designed for standard 12V winch circuits and control switch wiring.
• Always verify your original relay part number and terminal layout before purchase.

What are the installation steps and wiring tips?

Installation is straightforward for anyone comfortable with basic electrical connections. The unit includes a simple wiring map: two small control wires for the in/out switch and larger battery and motor posts; protective caps help keep the terminals safe after installation.

• Connect green/black control wires to the winch switch leads for in/out control.
• Attach black and red heavy leads to the battery terminals; blue/yellow to the winch motor.
• Secure mount to chassis and replace post caps to prevent accidental shorts.
• Test operation with engine off first, then under normal conditions to confirm proper function.

How durable and weatherproof is the KanSmart contactor?

The housing is powder-coated steel with weather-resistant seals, providing enhanced resistance to road grime, moisture and vibration compared with many OEM plastic relays. Each unit is tested before shipment to help ensure reliable performance after installation.

• Powder-coated steel body improves mechanical strength and corrosion resistance.
• Sealed posts and included caps reduce exposure to water and dirt.
• Quality-checked before shipping to minimize early-life failures.
• Backed by a one-year replacement warranty for added peace of mind.

Who is this for: Off-road riders, farmers, trail riders and utility vehicle owners who need a dependable, direct-replacement solenoid for 12V ATV and UTV winches. If your winch switch no longer changes spool direction, the original relay is corroded, or you want a sturdier, weather-resistant contactor compatible with many WARN-style reference part numbers, this KanSmart unit is a practical, serviceable option. Verify fitment against your existing relay part number and terminal layout before ordering to ensure a straightforward install.
