MaySpare Starter Solenoid Relay Switch for Polaris Sportsman 250-700 — 12V Direct-Fit with High-Temp Coil

MaySpare Starter Solenoid Relay Switch is a direct-fit 12V replacement for Polaris Sportsman models 250 through 700 that restores reliable starting without splicing or modification.

If your ATV or UTV refuses to turn over or the starter engagement feels inconsistent, a worn or failed solenoid relay is often the culprit. This MaySpare unit is built to match common OEM numbers and mounting, using high-temperature copper coil windings and a reinforced plastic housing designed to resist heat and vibration under typical off-road conditions. It installs in the factory location and connects to the existing terminals for a straightforward swap.

Which Polaris models and part numbers does this solenoid replace?

This relay covers a wide range of Polaris Sportsman machines and cross-references multiple OEM codes for easy identification. Confirm compatibility by comparing the listed numbers with your current part before purchase.

• Fits Polaris Sportsman 250, 300, 335, 400, 500, 600, 700 model range.
• Cross-replaces OEM codes: 4010930, 4011335, 3085521, 3087196, 3083211.
• Also compatible with aftermarket references like Arrowhead SMU6004 and TUCKER ROCKY 463740.

How durable and heat-resistant is the MaySpare solenoid?

The relay is engineered for intermittent starter duty with components selected to withstand the thermal and mechanical stresses common in ATV use. The coil uses high-temp (180°C) copper wire and the outer shell is a reinforced plastic blend for extra heat resistance and impact durability.

• 180°C copper coil windings for improved thermal tolerance.
• Robust plastic housing resists heat and vibration on trails.
• Designed for intermittent duty typical of starter relay operation.

How straightforward is installation—do I need special tools or wiring?

Installation is made for convenience: the unit is a direct plug-and-play replacement matching the factory mounting and terminal layout. No splicing is required, but basic hand tools are needed to secure the terminals; avoid over-tightening the nuts to prevent thread or terminal damage.

• Direct replacement: matches factory mounting orientation (Flat 180/F180).
• Three terminal layout mirrors original solenoid—no rewiring necessary.
• Use common wrenches/sockets; tighten connections snugly but do not over-torque.

What should I expect after replacing the solenoid relay?

Once installed, the starter circuit should engage reliably when the ignition or start switch is activated, eliminating intermittent clicks or failure to crank associated with a failing relay. If electrical symptoms persist, further diagnosis of battery, starter motor, and wiring is recommended.

• Restores consistent starter engagement when the solenoid is the root cause.
• Reduces clicking or non-crank conditions attributed to relay failure.
• If problems remain, check battery charge and starter motor health next.

Who is this for: This MaySpare starter solenoid relay is intended for Polaris Sportsman owners and ATV/UTV technicians who need a reliable, OEM-compatible replacement without custom wiring. It's a practical choice for riders maintaining older machines or repairing starter-related failures, and for anyone seeking a robust, heat-resistant relay that installs quickly and restores normal starting function.
