The cigarette lighter fuse of the Ruifeng M4 (check deal price | model details) is located in the fuse box next to the engine. The fuse is an electrical component that protects the circuit. When the current abnormally increases to a certain height and heats up, it melts and cuts off the current, thereby protecting the safe operation of the circuit.
The car's cigarette lighter draws direct current from the car's generator. As long as the car engine is running, it drives the generator to produce electricity, and all the electricity used in the car comes from it. If you need to use the cigarette lighter for a long time or the device has high power, you should start the car engine to increase the power, so as not to consume the car battery.
The car cigarette lighter must not be filled with foreign bodies to avoid damage. If the vehicle is equippeda cigarette lighter protective cover, cover it in time. The correct way to use a cigarette lighter is to insert and remove it vertically. Do not remove it by shaking it. Frequent shaking can easily cause the cigarette lighter fuse to become loose and short circuit. external devices. Since you have to touch the heating wire when lighting a cigarette, be careful not to press too hard on the heating wire. If tobacco or other objects fall into the heating wire, clean it in time to prolong the life of the cigarette lighter.

1. The engine makes a whistling sound, which is usually the same as steam or air coming out of the engine. , after hearing this noise, the engine will quickly lose power. Possible problem, engine overheats, check cooling system. The exhaust system is clogged, the suction pipe is leaking oris broken.
2. When I stepped on the accelerator, I found that the acceleration was not obvious, there was a lack of power, and the engine made a hysterical noise. The times most likely to occur are when the engine is hot or cold, or when it is low on oil. The causes of these problems can be divided into air filter, spark plug, ignition wire, gasoline, fuel filter, carburetor, oil pump and other problems. Check if the air filter is dirty, if the spark plug is old and needs to be replaced, if the ignition coil is broken, and if the gasoline is not clean, such as water in the fuel line. 'oil. Also check the oil pump.
3. A very loud noise comes from the exhaust, which is very annoying. Sometimes a similar noise comes from the front. The main problem is the exhaust system. Check if the exhaust pipe is broken.
4. Enginemakes a kicking sound, like the sound of a pencil hitting the table. The sound increases as engine speed increases. The possible cause is that there is dirt inside the engine. It is recommended to change the oil, filter and clean the engine. Others may be a valve problem.
5. When driving, acceleration is normal and ignition may be normal. However, if you drive at a constant speed, you notice that the engine speed is too high but the speed still seems to be. unable to increase. Try checking the coolant. Oil pressure is too high or too low. Check the pressure gauge. There may be a problem with the ignition time setting, which may also cause such symptoms. As with others, it could be an internal problem with the engine, such as a clogged EGR valve.
6. When the motor is running, it makes a clicking sound, as if something is hitting itare metal. When accelerating, when driving, you may not be able to hear it. This may be due to the cylinder valve, which can be changed by adjusting the valve. Lack of engine oil can also cause similar problems and engine oil pressure is relatively low. Check the engine oil pressure.
7. When accelerating, the engine will make a whirring sound, or it will also sound when decelerating. In short, the sound will change as the regime changes. The possible reason is lack of power steering oil, fill it up. The generator bearings could be damaged. Problems with the power steering pump and water pump will produce similar noises.
8. When you press the gas pedal, you will hear a clicking noise coming from the exhaust pipe. The sound may not be very loud and the car will not drive abnormally, as well ase fuel consumption. will increase. It is recommended to check the muffler and exhaust pipe for damage.
