Introduction

Generators are a highly practical tool used for a variety of private and industrial applications. Industry giants like Honda are renowned for their vehicle manufacturing triumphs and have easily moved into the generator market with products like eh EM5000S.

This generator is thought to be an excellent addition to any small building project or RV enthusiast. However, owners have become increasingly frustrated with recurring problems associated with these innovative machines. Therefore, this article will highlight the most common associated problems along with the best methods of troubleshooting.

Honda EM5000S Generator Troubleshooting

 1. Fuel Filter

a fuel filter

Petroleum-based fuel is the critical ingredient that allows all combustion engines to function. Although there are several styles available, they all function under the same principles.

These engines require flammable fuel to be injected into a combustion chamber which is compressed and ignited. The mini explosion uses the kinetic energy produced to push a piston rod when it transfers its energy into a spinning crank.

In the case of a Honda EM5000S generator, this combustion energy is then used to operate an alternator to produce transportable electrical energy.

However, this complex process relies on fuel to be clear of contaminants, as any tiny piece of material can compromise the inner engine components that function within a minuscule tolerance margin.

Although modern fuel is generally well-treated and free from contaminants, the Honda EM5000S generator is still equipped with a fuel filter. This filter is a small mesh that is installed between the fuel tank and the combustion area. Fuel is passed through the filter, which will catch and hold any particles that try to pass through the fuel lines.

fuel filter becoming clogged

However, the Honda EM5000S generator is renowned for the fuel filter becoming clogged prematurely. In this instance, it will cause a number of problems, including difficulty, in starting the engine, turning it off unexpectedly, power performance, and misfiring.

Many have commented that the primary issue is that the factor filter installed is too fine, which means that is severely inhibits the rate of fuel aver just a tiny build-up on the filter mesh.

Moreover, the issues are directed at the size of the filter, with users suggesting that the filter should be larger, which would allow the need for replacements to be considerably longer.

Ultimately, regularly inspecting and replacing the filter is necessary to prevent any fuel contamination and flow issues. Additionally, it is imperative that clean high, quality fuel is used at all times to guarantee that particle build-up is kept to a minimum.

2. Air Filter

A combustion engine is effectively the production of a controlled explosion that is created to harvest the kinetic energy produced in the process. In essence, the base of all combustion engines is the production of fire.

Fire requires three critical components, oxygen-rich air, fuel, and ignition. Should any of these three essential elements be compromised, it will prevent the necessary explosion and deplete the potency of the generator.

The Honda EM5000S is infamous for having a temperamental air supply which can cause frustrating operational issues that are difficult to diagnose. Specifically, the Honda generator is known for having an insufficiently sized air inlet port which can easily fail and prevent an adequate amount of air from entering the system.

Along with an improperly sized air inlet, the air filter becomes another directly related issue. The air filter is known for filling prematurely, preventing air from easily passing into the engine. Similar to the fuel filter, owners have complained about the insufficient size and unnecessarily dense filter, which prematurely prevents an adequate flow of air.

The best means of tackling this issue is to frequently clean the air inlet and filter area of the Honda EM5000S. Moreover, often these generators are used in more challenging environments like building sites.

These locations often have a lot of particle build-up in the air, which will ultimately be absorbed by the generator. It is essential to be mindful of these environmental factors and adjust the servicing and filter replacements as necessary.

3. Energy Efficiency

Energy Efficiency

The purpose of the Honda EM5000S generator is to produce electrical energy in challenging environments where the main power is unavailable. Therefore it is essential that the core foundation of the generator is to produce energy as efficiently as possible.

The production of energy is reliant on the supply of expensive petroleum-based fuel available. However, this is a key point of contention for owners that suggest that the Honda generator does not perform adequately.

Most notably, it is suggested that the generator is far less energy efficient in colder environments. Effectively, it is thought that the generator becomes sluggish and ineffective when the temperature begins to drop.

viscosity of the engine oil

This is most likely due to the viscosity of the engine oil combined with the contraction of the metal and plastic engine components that compromise the highly refined combustion processes. In simple terms, the generator becomes tight and sluggish, ultimately producing less energy per liter of fuel.

This is particularly frustrating for RV owners who are well equipped to travel in bitterly cold conditions to access their beloved rural nature. The best course of action is to try to ensure that when the power is being produced, every watt is being utilized and that, ideally, the generator is sheltered from blisteringly cold winds and rain.

4. Noise Levels

Noise Levels

After several months of ownership and regular use, it is noted that the generator begins to produce a louder level of noise. It may seem unusual, but many customers have suggested that after several hours of use, there is a definite change in the noise produced by the generator when in operation.

This issue has baffled users for some time. However, there appears to be a clearer explanation. When the generator’s engine is running, it is continually exposing the unit to intense vibrations for long periods of time.

Beyond this, the generator becomes increasingly hot the longer it is in use, and by extension means that the composite material are also exposed to high temperatures. When the generator is not in use, it is typically kept in colder areas such as garages and sheds, exposing it to temperatures at the other end of the extremes.

garages and sheds

Effectively, this wiggles and warps the tightly constructed generator, causing gentle loosening to come off the materials that make up the unit. The looser it gets, the louder the vibration is heard while it is on.

The only effective means of dealing with this frustrating issue is to continually ensure that all of the accessible screws and bolts are continually tightened to minimize additional vibration noise. To be extra diligent, thredlock gel can be placed on these bolts to ensure that they remain tightly in place for as long as possible.

5. Overheating

too much heat

Like every combustion engine, heat generation is one of the biggest ongoing concerns. When engines are exposed to too much heat for long periods, it will eventually wear them down and drastically reduce their lifespan. Unfortunately, this is a common problem associated with the Honda generator EM5000S.

Cars use the air that passes through the engine as it moves, combined with an intricate pressurized cooling system to ensure it does not reach unsafe temperatures. However, generators are designed for portability and simplicity in mind.

They lack a sophisticated cooling system, relying heavily on uninsulated exposure to the air to dissipate heat into the atmosphere and away from the components. Sadly, the Honda generator appears to inadequately perform this task which results in some units overheating and becoming damaged.

The likely cause of this problem is that the well-designed generator is overly compact . Effectively it is thought that the design was focused too heavily on it being transportable and lightweight that the center mass has been compacted into a dense and complex hunk of metal and plastic.

RV vacations

It should be noted that this generator is not designed for intense, long-term industrial application. It is better suited to private individuals using it during RV vacations, and small building projects. Therefore, it is difficult to blame Honda for poor quality design and manufacturing or the improper use of the generator.

To be on the safe side, there are some simple heat minimization techniques that can be highly effective. Firstly, ensure that the oil is changed regularly. Oil is the key lubricant that allows the internal metal components to move with minimal friction.

Older oil is less effective as lubricating joints, which means it will produce excess heat. Additionally, ensure that the generator is operated in open environments with plenty of airflows. This will allow for heat to more easily dissipate into the atmosphere and prevent it from building up in an enclosed space.

Conclusion

  1. My Honda 5000 will start run 30 to 45 seconds and running perfectly but it quits. Seems like it’s out of gas ! I see the comment about gas levels being important. I will try again with more in the tank!

    • Two guestions:
      What determines the amount of fuel left in tank to cause engine to shutdown? I understand there is a low oil level shutdown, too.
      Where is/are fuel filter[s]? My EM5000S manual shows a carb fuel bowl dissimilar than on engine.
      A clugged fuel filter would create the same effect! Thanks!
