The Arctic Cat Alterra 700 is a popular ATV known for its power, durability, and versatility, making it a favorite among riders tackling tough trails and demanding workloads. However, like any complex machine, the Alterra 700 isn't immune to problems. Understanding these common issues, and more importantly, knowing how to address them can save you time, money, and frustration, keeping you on the trail instead of stuck in the garage.

Let's Talk About Those Pesky Engine Issues

One of the most crucial aspects of any ATV is its engine. The Alterra 700's engine is generally reliable, but some common problems can arise.

Starting Problems: A frequent complaint is difficulty starting, particularly in cold weather. This can stem from several culprits:

  • Weak Battery: Batteries lose their charge over time, especially in cold conditions. Consider a battery tender or trickle charger to maintain optimal battery health. A load test can confirm if the battery is the issue.
  • Faulty Starter Solenoid: The solenoid is a small electrical switch that sends power to the starter motor. If it's clicking but not engaging, or not clicking at all, it might be faulty. Replacing the solenoid is usually a straightforward fix.
  • Clogged Fuel Injector: Over time, fuel injectors can become clogged with deposits, hindering fuel delivery. Fuel injector cleaner added to the gas tank can sometimes resolve the issue, but in severe cases, professional cleaning or replacement might be necessary.
  • Loose or Corroded Connections: Check all electrical connections, especially around the battery, starter, and solenoid. Clean any corrosion with a wire brush and apply dielectric grease to prevent future corrosion.

Engine Overheating: Overheating can cause serious damage to your engine. Here's what to look out for:

  • Low Coolant Level: Regularly check the coolant level in the radiator and overflow tank. Top it off with the correct type of coolant as needed.
  • Clogged Radiator: Mud, debris, and even insects can clog the radiator fins, reducing its cooling efficiency. Use a garden hose (avoiding high pressure) to carefully clean the radiator.
  • Faulty Thermostat: The thermostat regulates the engine's temperature. If it's stuck closed, it will prevent coolant from circulating properly, leading to overheating. Replacing the thermostat is a relatively simple and inexpensive repair.
  • Damaged Water Pump: The water pump circulates coolant through the engine. If it's failing, it won't provide adequate cooling. Listen for unusual noises coming from the water pump area, and inspect for leaks.

Loss of Power: A sudden or gradual loss of power can indicate various engine problems.

  • Dirty Air Filter: A clogged air filter restricts airflow to the engine, reducing performance. Clean or replace the air filter regularly, especially in dusty conditions.
  • Spark Plug Issues: A fouled or worn spark plug can cause misfires and power loss. Inspect the spark plug and replace it if necessary. Ensure you're using the correct type of spark plug for your Alterra 700.
  • Fuel Pump Problems: A failing fuel pump may not deliver enough fuel to the engine, causing it to run lean and lose power. Fuel pressure can be tested to diagnose this issue.
  • Valve Problems: Worn or damaged valves can lead to compression loss and reduced engine performance. This often requires a more in-depth engine inspection and repair.

Transmission Troubles: Shifting Gears on Solutions

The transmission is another critical component of your Alterra 700. Here are some common issues and how to handle them:

Difficulty Shifting: Problems shifting gears can be frustrating and even dangerous.

  • Incorrect Shift Linkage Adjustment: The shift linkage connects the shifter to the transmission. If it's misadjusted, it can make shifting difficult. Refer to your owner's manual for instructions on how to adjust the shift linkage.
  • Worn or Damaged Shift Cable: The shift cable can stretch or break over time, making shifting difficult or impossible. Inspect the cable for damage and replace it if necessary.
  • Low Transmission Fluid: Check the transmission fluid level and top it off as needed. Use the correct type of transmission fluid as specified in your owner's manual.
  • Internal Transmission Damage: In some cases, difficulty shifting can indicate internal transmission damage. This may require professional repair or replacement.

Slipping Transmission: Transmission slippage occurs when the engine revs up but the ATV doesn't accelerate properly.

  • Worn Clutch (If Equipped): Some Alterra 700 models have a clutch. A worn clutch can cause slippage, especially under heavy load. Replacing the clutch is usually the solution.
  • Contaminated Transmission Fluid: Contaminated transmission fluid can reduce its lubricating properties, leading to slippage. Flush the transmission and replace the fluid with fresh fluid.
  • Internal Transmission Damage: As with shifting problems, slippage can also indicate internal transmission damage.

Noisy Transmission: Unusual noises coming from the transmission can be a sign of trouble.

  • Low Transmission Fluid: Check the transmission fluid level and top it off as needed.
  • Worn Bearings or Gears: Worn bearings or gears can cause grinding, whining, or clunking noises. This usually requires professional repair or replacement.
  • Damaged Chain or Belt (If Equipped): Some models utilize a chain or belt drive system. Inspect for wear and tear, and replace if necessary.

Suspension and Steering: Keeping You on Track

A smooth and responsive suspension and steering system are essential for a comfortable and safe ride.

Worn Suspension Components: Over time, suspension components like shocks, bushings, and ball joints can wear out.

  • Leaking Shocks: Leaking shocks indicate that the seals are failing, and the shock is losing its damping ability. Replace the shocks with new ones.
  • Worn Bushings: Worn bushings can cause excessive play in the suspension, leading to a bumpy ride and poor handling. Replace the worn bushings.
  • Loose Ball Joints: Loose ball joints can cause steering instability and even be dangerous. Inspect the ball joints for play and replace them if necessary.

Steering Issues: Steering problems can make it difficult to control your ATV.

  • Loose Tie Rod Ends: Loose tie rod ends can cause steering wander and make it difficult to keep the ATV pointed straight. Inspect the tie rod ends for play and replace them if necessary.
  • Bent Tie Rods: Bent tie rods can result from impacts with rocks or other obstacles. Replace the bent tie rods.
  • Worn Steering Stem Bushings: Worn steering stem bushings can cause excessive play in the steering, making it feel loose and unresponsive. Replace the worn bushings.
  • Power Steering Problems (If Equipped): Models equipped with power steering can experience issues with the power steering unit itself, leading to a loss of power assist.

Electrical Gremlins: Chasing Down the Short Circuits

Electrical problems can be frustrating to diagnose and repair.

Blown Fuses: Blown fuses are a common electrical issue.

  • Overloads: Overloads occur when too much current flows through a circuit, causing the fuse to blow. Identify the cause of the overload and correct it before replacing the fuse.
  • Short Circuits: Short circuits occur when a wire comes into contact with ground, creating a path of low resistance. This can cause the fuse to blow. Trace the wiring to find the short circuit and repair it.
  • Faulty Components: A faulty component, such as a light or switch, can also cause a fuse to blow. Disconnect the component and see if the fuse still blows.

Lighting Problems: Issues with headlights, taillights, and turn signals are common.

  • Burnt-Out Bulbs: Check the bulbs and replace them if they are burnt out.
  • Loose Connections: Check the wiring connections to the lights and make sure they are secure.
  • Faulty Switches: A faulty switch can prevent the lights from working. Test the switch and replace it if necessary.

Charging System Problems: Issues with the charging system can prevent the battery from charging properly.

  • Faulty Stator: The stator generates electricity to charge the battery. If it's failing, the battery won't charge properly.
  • Faulty Voltage Regulator: The voltage regulator regulates the voltage from the stator to prevent overcharging the battery. If it's failing, it can damage the battery.
  • Loose or Corroded Connections: Check all electrical connections in the charging system and clean any corrosion.

Frequently Asked Questions

  • Why is my Alterra 700 hard to start in cold weather? Cold weather reduces battery performance and can thicken engine oil, making starting more difficult. Use a battery tender and consider a lighter-weight oil for winter use.
