What Is A Champion Generator?

Champion generators are portable power solutions that convert mechanical energy into electrical energy. They are equipped with an engine that drives an alternator which in turn is responsible for producing electricity. With their compact design and diverse power output options, Champion generators have become a trusted choice among homeowners, outdoor enthusiasts and professionals in various industries.

Champion Generator Problems

1. Generator Won’t Start Problem

One of the most frustrating issues you may encounter with your Champion generator is when it refuses to start and several factors could contribute to this problem like;

  • Low fuel in the tank
  • Dirty or faulty spark plug
  • Faulty or clogged carburetor

Troubleshooting The Generator Won’t Start Problem

  • First you need to check the fuel level in the generator’s tank and if it’s low then you shiuld refill it with fresh gasoline.
  • Also make sure that the spark plug is clean and properly connected because a dirty or faulty spark plug can prevent ignition. Inspect the air filter for dirt or debris.
  • If all the above elements check out then the issue may lie with the generator’s carburetor because carburetors can become clogged or damaged over time leading to starting problems. It is then advisable to consult a professional technician for carburetor cleaning or repairs.

2. Low Power Output Problem

Another common problem with Champion generators is a decrease in power output. If you notice that your generator is not providing the expected amount of electricity then you need to look at;

  • The load the generator has to carry
  • The voltage regulator
  • The generator’s RPM range

Troubleshooting The Low Power Output Problem

  • You should start by checking the load on the generator because if you have connected too many appliances or devices, the generator may not be able to handle the power demand so you need to remove some of the devices or prioritize their usage.
  • Also inspect the generator’s voltage regulator because a faulty voltage regulator can result in inconsistent power output and also test the regulator using a multimeter and replace it if necessary.
  • Finally make sure that the generator’s engine is running at the correct speed by referring to the Champion generator’s user manual for the recommended RPM range and adjust it accordingly.

3. Generator Shuts Off Problem

If your Champion generator keeps shutting off unexpectedly then it can be a frustrating and potentially dangerous problem. This is usually caused by;

  • A blocked fuel system
  • A low oil level
  • Bad oil

Troubleshooting The Generator Shutting Off Problem

  • First check the fuel system for any clogs or blockages because a dirty fuel filter or a faulty fuel pump can disrupt the generator’s fuel supply thus leading to unexpected shutdowns.
  • Be sure to clean or replace the fuel filter and inspect the fuel pump for proper functioning.
  • Also check the generator’s oil level and condition as low oil levels or contaminated oil can trigger an automatic shutdown as a safety measure.
  • Make sure the oil level is adequate and replace the oil if it appears dirty or degraded.
  • If none these steps solve the problem then it is advisable to seek professional assistance to repair any underlying electrical or mechanical problems.

4. Leaking Fuel Tank Issue

A leaking fuel tank in your Champion generator not only makes the generator a safety hazard but can also lead to fuel wastage and poor performance. This issue is likely due to;

  • A damaged fuel tank
  • Damaged fuel lines

Troubleshooting The Leaking Fuel Tank Issue

  • First you should start by turning off the generator and allowing it to cool down and then locate the source of the leak, which is often a cracked or damaged fuel tank. If the damage is minimal then you may be able to repair it using epoxy or a fuel tank repair kit.
  • Clean the area around the leak then apply the repair material according to Champion’s instructions and then allow it to cure.
  • However if the damage is extensive or the repair attempts are unsuccessful then it is recommended to replace the fuel tank entirely. This is whereby you should always consult an authorized service center or contact Champion customer support for assistance in obtaining a genuine replacement fuel tank.

5. Excessive Noise or Vibrations Problem

While Champion generators are known for their quiet operation, excessive noise or vibrations can still occur due to various reasons like;

  • Loose mounting bolts
  • Obstructions in the exhaust system

Troubleshooting The Excessive Noise or Vibrations Problem

  • You should start by inspecting the generator’s mounting bolts because over time these bolts can become loose causing the generator to vibrate excessively. You should tighten the mounting bolts securely to reduce vibrations.
  • Also examine the generator’s exhaust system for any obstructions or damage because a blocked or damaged exhaust can result in increased noise levels and clear any debris or obstructions and repair or replace the exhaust system if necessary.
  • It is highly recommended to consult a professional technician to diagnose and resolve any other underlying mechanical issues.

How To Prevent Champion Generator Problems

  • Start by reading the Champion generator’s user manual and familiarize yourself with the recommended maintenance schedule and procedures.
  • Be sure to regular change the oil as recommended by Champion for their generators.
  • Also clean and replace any clogged or dirty air filter to keep your generator’s engine running optimally for longer.
  • Inspect the spark plugs regularly and be sure to clean or replace with new ones when the old ones have become dirty.
  • Make sure that the fuel system is clean by always using fresh and clean fuel for the generator.
  • Be sure to store your generator in a clean and dry area when not in use and protect it from extreme weather conditions.

Can I Use My Champion Generator Indoors?

No, Champion generators should only be used outdoors or in well-ventilated areas. The exhaust fumes from the generator contain carbon monoxide, which is a poisonous gas and can be lethal if inhaled in high concentrations.

Can I Run My Champion Generator On Natural Gas?

Some Champion generators are dual-fuel capable meaning they can run on both gasoline and natural gas. However not all models have this capability. You should refer to Champion’s specifications or consult the user manual to determine if your generator can be operated with natural gas.


A well-kept Champion generator is a valuable asset that can help keep the electricity running through your household even when the main power has gone out and by following the troubleshooting tips provided in this article, you can effectively deal with the common issues that may arise with your Champion generator. This way you can ensure its longevity and the uninterrupted power supply it can offer when you need it most. Just remember to keep an extra batch of fuel to ensure the generator doesn’t run out of juice to power it up.
