Troubleshooting Polaris Ranger 800 Crew No Start

Troubleshooting a Polaris Ranger 800 Crew that won’t start is pretty straightforward. Watch the video above and follow the tips below to troubleshoot a Polaris UTV that won’t start.

Tools Needed – Polaris UTV No-Start Troubleshooting

Multimeter

A decent digital multimeter is an essential tool every side-by-side owner should have. It’ll come in handy not just for your UTV, but also for use on other vehicles and for electrical problems around your house.

Battery Tester

A battery tester might be expensive, but if your fleet comprises more than just your UTV, owning a battery tester is a diagnostic tool that will pretty much pay for itself. 

Smart Battery Charger or Battery Tender 

A smart charger can charge any type of battery, including the new lithium batteries commonly found on powersports machines. However, a smart charger could be pricey. A battery tender, on the other hand, is more affordable but takes longer to charge a battery. It’s capable of keeping a battery charged and in good health when it’s not in use, perfect for when a UTV is in storage.

Troubleshooting Polaris Ranger Crew No Start - Voltage Reading

The first step to troubleshoot a UTV battery is to take a voltage reading.

Set your multimeter to DC volts, then connect the multimeter to the positive and negative battery terminals. The reading should be 12.5 volts or above. If the reading is below 12.5 volts but above 6 or 7 volts, the battery might still be serviceable. However, if the reading is below 6 volts, it’s more than likely the battery is done and will need to be replaced. Either way, the next step is to try charging the battery.

Troubleshooting Polaris Ranger Crew No Start - Charge the Battery

Connect the battery to a battery charger, and leave it charging for a couple of hours. Once the battery has been charged, take another voltage reading.

If the voltage reading is 12.5 volts or above, the battery is fully charged and is good to go. However, if the reading is still below 12 volts, the battery is no longer serviceable and will need to be replaced.

Troubleshooting Polaris Ranger No Start - Test the Battery

Connect the battery to a powersports battery tester to accurately diagnose whether the battery is in good or bad health.

If the diagnosis shows the battery is still healthy, try charging it some more and then taking another voltage reading. However, if the diagnosis shows the battery is no longer healthy, it’s time to get a new one.

Troubleshooting Polaris Ranger No Start - Preparing a New Battery

Your Polaris UTV’s new battery will need to be filled with electrolyte and then charged.

Remove the caps from the top of the battery, then press the electrolyte bottle onto the battery and let all the electrolyte drain into it. Next, remove the bottle and reseal the battery. Connect the battery to a battery charger, and let it charge for several hours. Once the new battery is charged, take a voltage reading to make sure it’s fully charged. The reading should be at least 13 volts.

Troubleshooting Polaris Ranger No Start - Installing a New Battery

To install the new battery, remove the negative wire from the battery terminal first, then remove the positive wire to avoid grounding out the positive on the vehicle.
