The Chinese ATVs have been popular since the 2000s. The Kazuma ATVs (All Terrain Vehicles) have not only been successful in North America, but also in other parts of the world. The success is due to its long list of features and an affordable price tag. The ATV offers good safety features as well. It has good off-road capability and offers features including a speed governor, ignition cutout, full suspension, and an electric start system. People use the vehicle for teaching their kids as well.

However, the Kazuma 150 and other quads may experience issues including electrical issues. These problems become even more common when the care and maintenance inspections and activities are not carried out. Below are some of the common Kazuma 150 cc electrical issues, and tips for solving them.

Battery Issues

Battery problems are quite common. Many of the electrical issues in an ATV may occur due to battery issues. To proceed with a battery check-up, you need a multimeter setup to check the voltage of the battery.

The multi-meter has the leads that should be kept on the negative and the positive terminals of a battery. After doing so, you will have to check the reading of the multimeter. If you get a reading of more than 12 volts, it is good enough. However, the battery requires replacement if the reading is less than 12 volts. Battery issues may often cause issues in starting the quad and the ATV. However, if the battery is fine, there may be some other issue in your ATV due to which it is experiencing problems. You also need to check the inline fuse. Sometimes the fuse does not make enough contact, and therefore the ETV fails to run.

Spark Issues

An ATV and the quad will not start if it is getting a weak spark or no spark at all. The fuel may not be ignited due to this low spark. For checking the spark plug, you need to plug it out of the engine. Now plug it in the spark plug wires. Place the plug on something that can ground it (for instance a cylinder). Now when you start the engine, you will find that spark is coming out, jumping, and moving to the grounded path. 

No spark

If you find that no sparks are coming out, it may be due to a loose wire. Many of the ATVs of Chinese origin face the issue of backing out of the wires (the male end of the wire is not held securely within the female end). In such conditions, you may have to check all the wires that connect to the ignition coil. You can find a loose wire through the inspection. A little push will ensure that the wire is secured. You can also use the electrical testers for checking the wires and the battery, and to find out the exact location of the power loss. You can easily replace a spark plug as it is quite affordable and comes cheap. While choosing the spark plug, you should see to it that it has correct gapping.

Bad Connections

Sometimes the starter button may have bad connections, due to which ATV may face starting issues. You can inspect the button to find out the problem. Remove the screws of the starter button and the assembly, and you will find that two wires are running to it. The assembly and the wire positions are held together by solder. The joint is very delicate. If it is broken, you need to solder it again so that the starter button starts to function. Sometimes the starter button may be damaged and may require a replacement.

Shorting Wires

If the fuse of the ATV gets blown every time it is cranked and started, it may be due to damage to the wires. The shorting of the wires may result in the blowing of the fuse. Check the wires to find out the damages and tears. You can fix the damaged parts by using electrical tape.

Fuel Issues

An ATV may not run well or may not start when it is not getting fuel. Fuel is the main energy source for the running of an ATV or any other automobile. Carburetors or fuel pumps are the most common causes of fuel issues. 

You can check the fuel line by removing it from the carburetor and by placing it on a container where it can catch gas. If the gas is flowing freely, the problem is with the carburetor. Sometimes the filter of the carburetor may become clogged. Therefore, the fuel fails to reach the engine in such conditions. Most of the time, the carburetors may require the replacement of the seat and the needle valve.

You can also inspect the spark plug to know whether fuel is coming to the engine or not. A dry spark plug (after starting the engine) shows that no fuel is coming to the engine. You can clean the carburetor with ether or a carburetor cleaner and then start the engine again.

The needle valve is another component that may play a role in the flow of fuel to the engine. If the needle valve of the carburetor gets corroded/damaged, the flow of fuel to the engine will fail. To overcome the issue, you may have to replace the necessary parts if it is not overcome by cleaning the carburetor.

Airflow Issues

Engines require proper airflow to burn fuel and to obtain energy. Improper airflow may also cause issues. Obstructions in the air filter may not allow proper airflow and therefore the component requires regular cleaning. In certain cases, it may also require a total replacement. Airflow may also be destroyed by issues with the carburetor exhaust pump. If the exhaust is blocked, the airflow is not adequate/proper. Ensure that all the mud and debris are cleaned from the electrical and other parts of the ATV. The exhaust should also be cleaned regularly and from time to time.

Compression Issues

Compression issues may also cause several problems in an ATV. Blown piston rings and leaking gaskets are often the cause of compression issues. Sometimes dirt may get into the engine, which ultimately damages the walls of the cylinder. You can carry out the leak-down test for checking the compression. A compression testing kit is available that can be used for the process. You will have to remove the spark plug of your quad and plug in the compressor testing kit at the same place.


Most of the wires of the ATVs are located beneath the seating area (near the engine). The wires found in the front or rear end of the vehicle are for the lights. Therefore, you should check the requisite areas to find out the problems. Timely maintenance of ATVs ensures that all the electrical connections and the other systems of the quad are in a good state, and you do not face any undesirable problems when you are using and riding it
