Troubleshooting Electrical Problems

Troubleshooting electrical problems in your Bennche Bighorn 400 can seem daunting. Yet, by understanding the common issues and their solutions, you can get back to your adventures quickly. Electrical hiccups can prevent your utility vehicle from starting or running at its best. We’ll explore the steps to identify and resolve these electrical woes efficiently. Let’s start with the basics: fuses, wiring, and the battery system.

Checking And Replacing Fuses

Fuses protect your Bighorn’s electrical components. A blown fuse can cause a malfunction in any part of the electrical system. To check, locate your fuse panel and examine each fuse. Look for a broken metal strip inside. If found, replace it with one of the same amperage. Carry spare fuses in your Bennche to fix issues on the go.

Inspecting And Repairing Wiring

Damaged wiring can lead to shorts or incomplete circuits. Begin by inspecting the wiring harness for any visible damage, corrosion, or loose connections. Use dielectric grease on connectors to prevent future corrosion. Secure loose wires with zip ties. In some cases, repairing wiring may require professional assistance.

Testing The Battery And Alternator

  • Inspect the battery for corrosion and clean terminals if needed.
  • Use a voltmeter to test the battery’s charge; it should read 12.6 volts or higher.
  • If the battery is low, charge it and retest. A battery that won’t hold a charge may need replacing.
  • Start your Bighorn and test the alternator’s output with the voltmeter; a healthy alternator will produce approximately 14 volts.

By following these essential troubleshooting steps, most electrical issues with your Bennche Bighorn 400 can be identified and resolved.

Addressing Brake And Suspension Issues

The Bennche Bighorn 400 is known for its reliable performance in rough terrains. To maintain this performance, it’s essential to keep the brakes and suspension in top condition. Regular checks can prevent most problems. Let’s dive into the steps for maintaining your Bighorn 400’s brakes and suspension.

Checking Brake Fluid Levels And Replacing Worn Brake Pads

Brake fluid is like the blood of your braking system. Low levels could mean worn brake pads or a leak. Here’s how to check and replace the fluid and pads:

  1. Locate the reservoir – It’s usually near the handlebars for easy access.
  2. Check the level – If it’s below the minimum mark, add fluid.
  3. Inspect the pads – Look for signs of wear, like thinning or uneven surfaces.
  4. Replace if necessary – Use a screwdriver to take out old pads and insert new ones.

Remember, always use the specific brake fluid type recommended for your Bighorn 400. Mismatched fluids can lead to brake failure.

Inspecting Shocks And Replacing Damaged Components

A smooth ride depends on good suspension. Shocks absorb bumps, but they can wear out. Follow these steps to inspect and replace them:

  • Look for leaks – Oil streaks on the shock body are a sign.
  • Test the bounce – Press down on the ATV. It should not bounce more than once.
  • Check for damage – Look for dents or rust on the shock body.
  • Replace if needed – Remove bolts with wrenches and swap out the damaged shock.

Use quality replacement parts to ensure the Bighorn 400’s longevity. Keep an eye on these systems to enjoy a safe, smooth ride.

Fixing Transmission Problems

Fixing Transmission Problems in your Bennche Bighorn 400 ensures a smooth and reliable ride. Regular maintenance plays a crucial role in preventing transmission complications. Learn efficient ways to keep your ATV in peak condition.

Regular Fluid Checks And Replacements

Transmission fluid is the lifeblood of your Bighorn 400’s transmission. It prevents overheating and wear. Check fluid levels every month. Replace the fluid according to the manufacturer’s recommendation which is typically every couple of years to ensure optimal performance.

  • Turn off the ATV and ensure it’s on level ground.
  • Locate the transmission fluid dipstick and check level.
  • Top up if the fluid falls below the recommended mark.
  • Change the transmission fluid when needed for smooth gear shifts.

Adjusting And Repairing Transmission Belts

A well-functioning transmission belt ensures efficient power transfer from your engine to the transmission. A loose belt can cause slippage while a tight one leads to wear. Check and adjust your transmission belt as follows:

  1. Locate the belt cover on the side of your Bighorn 400.
  2. Remove the cover to inspect the belt.
  3. Adjust the tension as needed for optimal grip.
