Cause analysis and solution
Overload
|
Using the vehicle electrical system under conditions for which it was not designed can overload it, causing fuses to blow or circuit breakers to trip.
Excessive fuse blowing or circuit breaker tripping due to overloading may eventually damage the speed controller or motor due to overheating. Brake pad or shoe rubbing due to faulty brake components or improper adjustment of brake line tension can also cause fuses to blow and circuit breakers to trip.
|
Please comply with the manufacturer’s requirements for the driving conditions of the electric scooter and do not overload or overload it.
|
Electrical component defects
|
Shorted wiring and defective electrical components (such as overheated motors and speed controllers) can cause the electrical system to draw too much power and lead to blown fuses and tripped circuit breakers.
|
Replace electrical components with qualified ones
|
Check by sight, touch, and smell
|
Remove the foot pedals or wiring covers and look for burnt or melted wires, wire connections, or electrical components.
Also look for loose, disconnected, or damaged wires or wire connections. Pull and push on all individual wires and wire connections to see if anything is loose or disconnected.
Put your nose close to the speed controller and motor and give it a sniff. Any component that looks burnt or melted or smells like burnt plastic is almost certainly defective and should be replaced.
|
Motors that smell like they are burning should be replaced to prevent damage to the speed controller.
|
Check the speed controller
|
Check the speed controller for burnt or melted wires or wire connectors. If any wires are burnt or melted, the speed controller is most likely faulty.
Smell the speed controller for burnt plastic or oil smells. If the speed controller has a burnt smell, it is faulty.
If the speed controller is not burnt, melted or smelling, it may still be faulty. Test other components of the electrical system and use a process of elimination to see if the speed controller is functioning properly.
|
If the speed controller is faulty, replace it.
|
Check the motor
|
Check the motor for burnt or melted wires or wire connections. Burnt or melted wires or wire connections indicate that the motor has overheated, which can cause the insulation on the motor’s copper wire windings to melt.
Smell the motor for burnt plastic. If the motor smells burnt, it indicates that its coils have overheated. Motors with overheated coils should always be replaced to prevent damage to the speed controller.
If the insulation on the copper windings melts, they will short out, causing the motor to not run or run slowly. Shorted motor windings can also burn out the speed controller because too much current is required, causing the speed controller to overwork and overheat.
|
If the motor is faulty, replace it.
|
The fuse started to blow after replacing the battery pack
|
If fuses or circuit breakers begin blowing immediately after replacing the battery pack or battery pack harness, the battery pack harness may not be properly connected to the battery.
|
Please connect the battery correctly
|
Fuse overload
|
Fuse overload, fuse failure or melting caused by poor contact.
|
Check your scooter’s owner’s manual or contact the manufacturer for the correct size fuse. Most electric scooters use fuses in the 20-40 amp range.
