Routine care and maintenance of
Used Car is important. Used Car will probably be hindered by water leakage from the electric wheels. Friends should note that Used Car should avoid being placed in humid places. Do not place it in a place where the temperature is too high or where there are corrosive gases to avoid chemical corrosion on the surface of the electroplated paint of the metal machine.
Used Car should avoid leaving the vehicle exposed to the scorching sun or rainy days, so as not to damage the components inside the controller, causing operating failure and causing service accidents. The structure of the electrical control part is complicated, and if you do not have enough installation and disassembly knowledge, please do not disassemble or repair without authorization. If the charging voltage is not strong in other places, the charger fuse may easily blow.
Nowadays,
Used Electric Car are very common. Because many elderly people may find it inconvenient to drive, the application of Used Car is constantly increasing. However, we will also encounter some common faults during use. Let`s take a look:
1. Loud noise is a common problem. The main reasons are:
①The bearing clearance in the motor is large.
② Scan the motor rotor.
③The magnet is loose or falling off.
④ Axial movement inside the motor.
⑤ The surface of the brushed motor commutator is oxidized, ablated, oily, uneven, and the commutator pieces are loose.
2. No display on the instrument panel is a common fault in micro Used
Electric Car. The main reason is that there is no voltage between the positive and negative leads of the instrument, a short circuit in the wire or connector, or the instrument is damaged.
3. If the wheel spins as soon as the power is turned on, and the speed increases very quickly, this kind of fault becomes "speeding". It is mostly caused by the poor contact cycle of the ground wire of the handlebar, or it may also be the fault of the controller.
4. The speaker is often out of control because the speaker is damaged, or the switch is damaged, or the connecting wire or connector is short-circuited. During maintenance, these aspects should be mainly checked.
