Is there any way to repair the power outage in the Tricycle Motorcycle circuit?

Today let`s take a look at the main factors that affect the power outage of Tricycle Motorcycle:

① Battery connection wire, if the screw of the battery connection wire is loose, poor contact or broken, for example, the simple battery is installed under the foot pedal, and the battery compartment cover can be powered on by pressing the broken wire, but if If they separate at the slightest jolt, they will lose power.
②Air 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, which will also cause air leakage. Switch jumps.
③The electric door lock core is loose. Over time, the lock core is broken and cannot be turned on well. When vibrating, the lock will have poor contact and power outage. Some locks have a lot of keys strung together, which will make it more troublesome. The lock cylinder is broken and the power is cut off first.
④ Wiring problems, such as whether there is poor contact in the battery connecting wire, there is poor contact in the line 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 rotates, as it is easy for the line to break.
If the meter does not light up and the Tricycle Motorcycle does not move away, the problem may be the answer above. If the meter does not light up but the car can still be driven, then there may be a problem with the connection line of the meter. Check whether the negative electrode has poor contact, and whether the solder joints on the circuit board inside the meter are loose.
