Basic knowledge of electric moped (5)

Other common faults and answers of electric mopeds 1. The power indicator on the instrument panel is off and the motor is running normally (1) There is no voltage between the positive and negative leads of the dial → poor contact of the connector or open circuit of the lead → reconnect or change the wire. (2) The luminous tube is damaged → replace the luminous tube. (3) There is an open circuit on the dial circuit board → replace the meter circuit board. 2. The motor stops when it rotates (1) The battery is low → charge the battery. (2) The battery contacts are in poor contact → adjust the position of the contacts or polish the contacts. (3) The fuse in the battery box andInsurance seatPoor contact between the two → adjust or replace to make it good. (4) There is dirt in the photosensitive tube of the photosensitive film in the adjustment handle → clean or replace the photosensitive sheet and wipe the photosensitive tube. If the fault still cannot be eliminated, replace the adjustment handle. (5) There is a fault in the controller → replace the controller. (6) The lead wire of the speed control handle seems to be broken → replace the lead wire. (7)brakePower offswitchFailure → adjust or replace the brake power-off switch. (8) Poor contact after the power lock is ablated → replace the power lock. (9) Virtual connection of connectors in the circuit → reconnect to make good contact. (10) Carbon brushes, wires, and windings in the motor are welded or connected → repair or replace the motor. 3. Use the key to turn on the power of the electric door lock, but the battery indicator on the instrument panel does not light up, and the motor does not rotate when the handle is turned on. What is the reason? (1) The fuse on the battery box is burned out, and the fuse needs to be replaced. (2) The fuse on the battery box is in poor contact, and the fuse must be in good contact. (3) The contacts on the battery box are in poor contact, and the contacts must be in good contact. (4) The contacts on the battery box are burnt out, and new contacts need to be replaced. (5) The electric door lock is burned out and needs to be replaced with a new electric door lock. (6) The lead wire of the battery in the battery box is broken, and the circuit is connected. (7) The internal circuit of the battery in the battery box is open, and the battery needs to be replaced. (8) The lead wire or contact lead of the electric door lock is open or in poor contact, and needs to be re-wired. 4. Use the key to open the electric door lock and turn on the power. The instrument panel battery indicator is on, but the motor does not rotate when the speed control handle is rotated. What is the reason? (1) The controller is damaged, replace with a new controller. (2) The speed control handle is damaged, replace it with a new speed control handle. (3) The brake power-off handle is damaged, replace the brake power-off handle. (4) If the motor is damaged internally, replace the motor with a new one. (5) The wire on the vehicle is broken, and the line is reconnected. 5. Open the electric door lock with the key to turn on the power, and the motor immediately rotates. What is the reason? (1) The speed control handle is damaged, replace it with a new speed control handle. (2) The controller is damaged, replace with a new controller. 6. After the battery is charged for 8 hours, the electric moped only runs 10 kilometers. What is the reason? (1) The battery is aging and should be replaced with a new one. (2) The motor is partially short-circuited and the current is too large. Replace with a new motor. (3) The controller is damaged, replace with a new controller. (4) The output voltage of the charger is low, and the battery is not fully charged. Replace with a new charger. 7. The speed of the electric moped is obviously not as fast as before. What is the reason? (1) Part of the motor is short-circuited, replace the motor. (2) The controller is damaged, replace the controller. (3) The speed control handle is damaged, replace the speed control handle. (4) Mechanical failure is not flexible.
