Starter Relay Solenoid for Polaris Sportsman and Hawkeye
Polaris Sportsman 300 / 400 / 550 Touring X2 XP and Hawkeye 300 - 2008 to 2014
This is a brand new starter relay solenoid switch for the Polaris Sportsman 300, 400 and 550 including the Touring, X2 and XP variants, and the Hawkeye 300. It is a direct replacement for the original unit, and every one is tested before it is shipped. All of the item pictures are accurate - if you are in any doubt, compare them against your original part before ordering.
The starter solenoid is the heavy duty relay that sits between the battery and the starter motor. The key switch cannot carry the hundreds of amps a starter draws, so instead it energises a small coil inside the solenoid, and that coil throws a set of contacts capable of handling the full cranking current. Everything about a solenoid failure follows from those contacts: they arc every time the engine is started, they erode, and eventually they no longer pass current cleanly. The classic symptoms are a single loud click with no crank, a starter that spins only sometimes, cranking that is noticeably slow even with a good battery, or nothing at all when you turn the key. This unit measures 38 mm high by 34 mm square with 57 mm between its fixing holes, and carries two wires, two terminals and two plugs.

Frequently Asked Questions
Will this fit without modification?
Yes, on the applications listed above. It is a direct replacement with the same 57 mm fixing centres, the same two heavy terminals and the same two plugs as the original, so it bolts and plugs straight in. Compare Polaris part number 4012013 against your original unit before ordering.
What is included?
The starter relay solenoid itself, with 100 mm wires. Reuse the mounting rubber, the terminal nuts and the insulating boots from your original installation unless they are damaged or corroded.
How do I tell whether the solenoid has failed?
With the key turned to start, check for battery voltage arriving at the small trigger wire. If the voltage is there and the solenoid does not click, the coil has gone. If it clicks but the starter does not turn, measure the voltage across the two large terminals while cranking - anything more than a few tenths of a volt dropped across a closed solenoid means the contacts are burnt. Check the battery and the earth strap first, since both produce the same single-click symptom.
Why do starter solenoids fail?
Contact erosion from arcing every time the engine is started, and corrosion where the unit is exposed to water and mud. A weak battery makes it worse, because the starter draws more current for longer and the contacts arc harder each time. Keeping the battery healthy and the terminals clean is the best way to make a new solenoid last.
