Every owner of ATV sooner or later faces its failure. And it does not matter whether you decided to buy an inexpensive ATV or a branded machine. Of course, this is an unpleasant situation, but most of the problems can be solved with your own hands. So let’s figure out what to do if the ATV does not start.
Common causes of malfunction
Constant riding at the limit and improper operation of the equipment often becomes the cause of a number of breakdowns. Because of high loads can fail:
- The battery.
- Starter.
- Commutator.
- Ignition system.
- The fuel system.
But more often, problems arise from some small thing, like low-quality gasoline, lack of oil or improper preservation of machinery.
Checking technical fluids
The first thing a motorcycle enthusiast should do if the ATV does not start or stalls is to check the gas tank. With prolonged idle time, the fuel may evaporate, and if the tank is empty, you should refill the gasoline. But if there is fuel in it, it is advisable to drain it. Very often you get low-quality fuel, which after a while simply ceases to ignite.
You should not forget about the oil. If low-quality fluid was poured into the system, the unit will lose dynamics and may even stall. This problem is especially acute for four-stroke quads, since their power unit must literally “swim” in oil.
Starting the engine after a long downtime
Another reason why the ATV does not start – improper preservation of equipment. Even if you leave the machine in the garage for a day, it should be prepared for downtime, otherwise starting the engine will become a real challenge.
For preservation it is necessary:
- Start the utility vehicle.
- Close the fuel tap.
- Wait until the remaining petrol in the carburetor is not used up. It takes about 5-10 minutes.
- Lift the seat of the machine.
Remove the fuse. It is also possible to dismantle the battery of the unit if the air temperature outside is low.
Many riders ignore such a simple procedure, but it is the one that most often causes problems with starting the equipment. For example, it is almost impossible to start a “cold” engine right away. Therefore, the driver begins to methodically press the “start” button, and at the same time the battery is discharged. Already after 10-15 attempts, the battery is saturated, and it becomes unreal to start the equipment.
Important: In severe frost it is necessary to carry out preservation of a scooter. If this is not done, the condensate will gather in the bottom of the carburetor and the ATV will have to “warm up” for several days.
Problems with the starter
The reason why the ATV does not start, can be the starter or damaged contacts. In this case, you should:
- Check the condition of the wires. Very often the starter contacts are oxidized, so they should be regularly inspected and cleaned.
- Check the starter relay. Here, too, oxidation can appear. Although the part is sealed, moisture can enter the device through microcracks. If the problem is in the relay, then it must be removed, cleaned of corrosion and oxidation. After that, the contacts are lubricated with a special grease composition.
However, if the damage is severe, it is better to replace the part.
But what to do if the Chinese ATV does not start because of problems with the starter in the field or far from home? In this case, the rider needs to close the relay contacts with a screwdriver. Thus, the rider will be able to start the machine bypassing the faulty starter.
No spark
Lack of spark is another simple but unpleasant failure. It usually occurs due to damage to the coil or breakage of the wires that go to the spark plug. Solving the problem is easy. The rider just needs to unscrew the spark plug, put it in the cap, put it with the metal part on the motor and press “start”.
