What should I do if the ghost fire electric car enters the water and does not leave?

Failure to repair the engine in time after water ingress can have a very serious impact on the engine.

1. There are two situations of moisture ingress into the engine

1. One is the water ingress into the cylinder combustion chamber, which is also the most common situation.

Forced start after burning water can sometimes damage the engine, but the combustion chamber water ingress car can not be released.

2. One is the crankcase water ingress, theoretically the crankcase water inlet cylinder should also enter, assuming that the cylinder does not enter, only a small amount enters the crankshaft chamber (into more than a start on the bad oil seal), in winter will freeze on, block the oil pipeline, summer will destroy the lubrication, resulting in overheating, but the hot gas should come out of the crankcase respirator tube.

2. Symptoms of water ingress into the engine.

First: Check whether the color of the engine oil is abnormal, if the oil turns milky white, it means that the engine is flooded.

Second: Check whether the pipes are flooded. Including the air filter and the casing under the air filter whether there are obvious traces of water ingress, and check whether there are obvious traces of water in the air intake pipe and air intake manifold.

Third: check whether there are traces of carbon deposits in the spark plug and engine cylinder wall, when the engine enters the water, because the water is difficult to be compressed, the piston can not reach the original top dead center position, the piston movement stroke becomes shorter, and the top dead center position will move down significantly.

Short-circuit protection, and when the water is dry, it will recover normally.

The easiest way to check the circuit drying. The circuit of electric vehicles is not complicated, especially the alarm device is mostly at the front of the car. FoundScrewdriversRemove the car shell, carefully check the circuit, wipe the water inside, and use a hair dryer and other tools to dry the internal moisture, so that the electric car can be placed in a ventilated dry position for a period of time, which can generally be solved.

Check the circuit and rule out the aging method. Many friends know that due to long-term use, the circuit of the electric vehicle will also age, and the internal wiring may also be exposed to the air at this time, so when it rains, the water may avoid the control of the switch and directly connect the alarm, therefore, you can find the aging place and then repair it yourself.

Removal of posterior subtraction method. If you really hate this kind of noise, or if this happens to electric vehicles when it rains, we can cut this circuit by discarding the function of the alarm and horn. Don't think that this situation is undesirable, many people do it, because the horn is not necessary, on the contrary, it is more careful to ride without a horn.

Unplug the power supply after rain. I often use this method, because the electric car will alarm itself, not only noisy, but also waste a certain amount of electricity, unplug the power at any time, and put it in a dry place, overnight the electric car will automatically return to normal, and do not have to work hard to check or cut the circuit, is it a few birds with one stone. You can try it.

The reason is that the circuit failure of the electric vehicle can be solved by drying the circuit; The specific operation is to use a screwdriver to unload the car shell, carefully check whether the circuit inside has dust or water, if there is a type of internal knowledge to wipe the water clean, and then use a hair dryer and other tools to dry the internal moisture, and finally put the electric car in a ventilated and dry position, put it for a period of time to observe whether the electric car is still ringing.

If it is the cause of the aging of the circuit, you can also find the aging place and repair it yourself; It may also be because the electric car is in the rain, in this case, it is recommended to unplug the power supply after the rain, and put it in a dry place, and the electric car will automatically return to normal overnight.

Ten common faults of electric vehicles:

One: After the electric car is opened, the dashboard does not light up and does not adjust the speed.

Two: Open the electric door lock and find that the whole car has no electricity.

Three: After the power is turned on, the instrument display is normal, but the speed is not adjusted.

Four: After the electric vehicle is charged once, the driving range is insufficient.

Five: Turn on the headlight motor does not rotate.

Six: Automatic power off during driving.

Seven: the battery cannot be charged.

Eight: The electric car obviously has electricity, but it doesn't go anyway.

Nine: After disconnecting the power supply, there is an inexplicable abnormal sound in the whole vehicle.

Ten: It's very laborious and hard to answer when riding, and the speed is always very slow.

What should I do if the battery car gets into the water and keeps ringing.

If this phenomenon occurs, this is mainly after the controller enters the water, the alarm system inside this has always wanted to appear in this case, it is necessary to disconnect the power supply of the battery, see if the sound of Zhiqing has appeared again, if it does not appear, then you can only disconnect the power supply, and then check the alarm. Take a look at the circuit of this alarm to see if there is a problem, and there is a need to check the controller of this battery car of this vehicle, whether the controller is faulty, these are all things that need to be specifically checked. If there is a problem, then it needs to be replaced or repaired with the fierce ants.

Hello, the electric car can not start the alarm because the switch in the circuit of the horn is damaged, and a switch needs to be replaced. Because the horn has been turned on without passing through the switch, the short circuit is separated by insulating tape. Moreover, the electric vehicle is buried in the rain and disturbs the water, resulting in a short circuit in the line.

If this happens, it is a problem with the circuit, and after this happens, you should go to a professional maintenance organization to repair the Hedan circuit. The circuit of the electric car horn is in the wiring harness liquid leakage of the handlebar, in the case of not understanding the circuit, it is not recommended to repair it yourself.

Electric vehicles are more afraid of water, and it is very common to turn on the key horn, alarm, or sound inside the electric car after rain. This is mainly due to the fact that the electric vehicle is flooded after being exposed to rain, resulting in a short circuit or failure of the controller or line above.

What should I do if the electric car keeps ringing when it gets into the water?

Electric vehicles are not suitable for immediate power-on driving after rain, especially in the event of heavy rain, must be dried before powering on. The electric car has been ringing is nothing more than the failure of the controller or its line water ingress, at this time turn off the power, and prevent the car from being left in a ventilated place to dry for 24-48 hours. Electric vehicles have a certain waterproof performance, and they can basically be restored to use after drying.

If it is stationary for 24-48 hours, and the power is still ringing, then you can check the control circuit of the electric vehicle at this time. The main place where water enters the controller is at the joint of the wire, and the water accumulation of the control plug-in will cause the electrical appliance to malfunction. Unplug the plugs one by one to drain the stagnant water and dry them with a hair dryer.

If it still doesn't help after drying, you can only send it to the repair shop for maintenance, after all, the problem of the line, it is still quite complicated, and it is best not to mess around if you don't understand. In addition, after the electric vehicle is exposed to rain, it is necessary to lubricate the iron parts in the key parts to avoid rusting of the parts.
