On trails or out on backroads, the Polaris Sportsman 570 is a force to reckon with. As a versatile all-terrain vehicle (ATV), it has been the go-to machine for off-road adventures and utility work alike. But like any other mechanical device, it can also be subject to various issues, one of which is starting problems. This writeup will serve as an in-depth guide to understanding, diagnosing, and resolving starting problems that you may encounter with your Polaris Sportsman 570.

Indications of Starting Problems

Before diving into the repair process, let’s identify the signs that indicate a starting problem with your Polaris Sportsman 570. Recognizing these signs is crucial in the early detection and prompt resolution of these issues.

Failure to Start

A clear sign of a starting problem is when your ATV refuses to start at all. This can happen suddenly, or it might follow a period of hard starting.

Inconsistent Starting

Another indication of a starting issue is when the machine starts inconsistently. Sometimes, it might start without a hitch, while at other times, it just doesn’t.

Engine Turning Over but Not Starting

Your Polaris Sportsman 570 may have a starting problem if the engine cranks over but will not actually start.

Having learned the key indicators of a starting problem, it is essential to comprehend the potential causes behind these issues to efficiently troubleshoot and repair your ATV.

Causes of Starting Problems

A range of causes can be responsible for the problems with starting your Polaris Sportsman 570. These causes can be categorized into fuel-related problems, battery issues, and ignition system troubles.

Fuel-Related Problems

A prime culprit behind the starting problems is often the fuel system. The issues can be caused by dirty fuel, clogged fuel filters, or problems with the fuel pump.

Battery Issues

A dead or weak battery often stands guilty behind the starting issues. Even a loose or corroded battery connection can initiate these problems.

Ignition System Troubles

A defective ignition switch, a faulty ignition coil, or a worn-out spark plug might also cause your ATV not to start.

Now that you are familiar with the possible causes of starting problems in your Polaris Sportsman 570, let’s delve into the solutions for these issues.

Solutions to Starting Problems

Solving Fuel-Related Problems

  1. Drain the tank and replace the dirty fuel with a fresh supply.
  2. If the problem persists, check the fuel filter. If it is clogged, replace it.
  3. If it’s not the fuel or the filter, inspect the fuel pump to see if it’s working. If it’s not, it might need replacement.

Addressing Battery Issues

  1. Begin by inspecting your battery voltage. A healthy battery should read around 12.5 Volts. If the voltage is below 12.0 Volts, you will need to charge or replace the battery.
  2. Examine your battery connections. Ensure they are tight and free of corrosion. If you find any loose or corroded connections, fix them immediately.

Fixing Ignition System Troubles

  1. Check your spark plugs for any signs of wear and tear. If they seem worn out, replace them.
  2. If the issue is with the ignition coil or ignition switch, you might need to get professional help as these parts can be intricate.

While understanding the starting problems in your Polaris Sportsman 570 ATV can be a bit complex, this guide tries to simplify it, providing insights into potential causes and their possible solutions. These tips might save you a service trip, especially when you are stuck on a trail or deep in the woods. However, if none of these methods seem to solve the issue, it is advised to contact a professional mechanic for more a comprehensive examination and targeted troubleshooting.
