How to Test a Polaris Voltage Regulator

A voltage regulator is an important component of any Polaris vehicle. It helps to keep the electrical system running smoothly and protects the battery and other electrical components from becoming overloaded. Testing a Polaris voltage regulator is a relatively simple process that can help you determine whether or not the regulator is functioning properly.

Tools Needed

In order to test a Polaris voltage regulator, you will need a few tools and supplies. These include:

  • Multimeter
  • Screwdriver
  • Replacement voltage regulator (if needed)

Steps for Testing a Polaris Voltage Regulator

Step 1: Disconnect the Battery

Before you begin testing the Polaris voltage regulator, it is important to ensure that the battery is disconnected. You should also make sure that the ground cable is disconnected.

Step 2: Remove the Voltage Regulator

Using a screwdriver, remove the screws that hold the voltage regulator in place. Carefully remove the regulator and inspect it for any signs of corrosion or damage.

Step 3: Test the Voltage Regulator

Using a multimeter, set it to the DC voltage setting. Connect one lead of the multimeter to the positive terminal of the voltage regulator and the other lead to the negative terminal. You should see a reading of 14.5 volts.

If the reading is not 14.5 volts, then the voltage regulator may be faulty and should be replaced.

Step 4: Reinstall the Voltage Regulator

Once you have tested the voltage regulator and determined that it is functioning properly, you can reinstall it. Make sure to tighten the screws securely and reconnect the battery and ground cables.

Tips for Testing a Polaris Voltage Regulator

Check the Fuses

Before testing the voltage regulator, it is important to check the fuses. If a fuse is blown, it will prevent the voltage regulator from functioning properly.

Check the Wiring

Inspect the wiring around the voltage regulator to make sure that it is secure and free from any signs of damage. If there are any frayed wires, they should be replaced.

Replacement Parts

If you determine that the voltage regulator needs to be replaced, make sure to get a replacement that is compatible with your Polaris vehicle.


Testing a Polaris voltage regulator is a straightforward process that can help you determine the condition of the component and if it needs to be replaced. As long as you have the proper tools and supplies, testing a Polaris voltage regulator should be a relatively simple process.
