Analyze the circuit failure of Tricycle Motorcycle and be calm

Although Tricycle Motorcycle are currently the main force in transporting boredom on construction sites, their performance is very powerful and the probability of failure is very small. However, there are always abnormalities in mechanical equipment. Line problems are more common. When problems occur in the lines, our first hand The main factors to consider that affect the power outage of Tricycle Motorcycle are:

1. The battery connection cable. If the screws of the battery connection cable are loose, have poor contact or are broken, for example, if the simple battery is installed under the foot pedal, the battery compartment cover can be powered on by pressing the broken cable, but If they separate at the slightest jolt, they will lose power.
2. Air switch, if it takes a long time, the air switch will trip when the current of the air switch is less than the maximum current of the electric vehicle. Of course, the main wire screws on both sides of the air switch will be burnt black if they are not tightened. This will also cause Air switch jumps.
3. The electric door lock core is loose. Over time, the lock core is broken and cannot be turned on well. When it vibrates, it will cause poor contact and power outage of the lock. Some locks have a lot of keys strung together, which will make it even more difficult. The lock cylinder will be damaged and the power will be cut off first.
4. Wiring problems, such as whether there is poor contact in the battery connection wire, there is poor contact in the wire from the battery to the lock, there is poor contact in the battery negative wire, etc.
Check the lines where the front of the car is turning around. This is where the lines are more likely to break. If the meter doesn't light up and the car doesn't run, the problem may be the answer above. If the meter doesn't light up but the car can still run, then there may be a problem with the meter's connection cable. For example, there is something wrong with the positive and negative poles of the meter. There is no bad contact, and whether the solder joints of the circuit board inside the meter are loose.
