How to Determine Whether the Electric Vehicle Motor or Controller is Faulty?

Disconnect all control wires connected to the controller, leaving only the power wires connected to the controller and the wires linking the controller to the motor. Use tweezers or a short wire to short-circuit the +5V and signal terminals of the connector, then observe whether the motor rotates. If the motor operates normally at this point, it indicates that the controller is not faulty, and the issue lies with the peripheral functional components. If the motor does not respond, turn off the power switch, disconnect the connected power wires and the wires linking the controller to the motor, completely separating the controller from the vehicle. Directly connect the power wires to the motor wires. Turn on the power switch and observe whether the motor operates normally. If the motor does not respond, it indicates that the motor is faulty.

How to Check the Mileage?

Mileage can be viewed on the car's odometer, which is located directly in front of the driver's seat. The mileage can be adjusted at auto repair shops or automotive electrical repair stores. The odometer consists of a speedometer and a mileage counter. Methods to verify the mileage: 1. Check the production date; 2. Inspect the car tires; 3. Examine the interior and listen for sounds; 4. Test the handling. The odometer is a digital instrument that operates through the engagement of the counter drum's transmission gear with the worm gear on the speedometer's drive shaft, causing the counter drum to rotate. Its characteristic is that when the upper drum completes one full rotation, the lower drum turns one-tenth of a rotation. Similar to the speedometer, modern odometers also include electronic versions, which obtain mileage signals from the speed sensor.

Is It a Big Problem If a Sedan Scrapes Its Undercarriage?

If a sedan scrapes its undercarriage, it's important to inspect the undercarriage. As long as there are no fluid leaks and no deformation of mechanical parts, the problem is not significant. The protection of a car's undercarriage is often the most overlooked aspect by car owners. The undercarriage is one of the most vulnerable parts of a vehicle, and proper undercarriage protection can provide better driving safety for the owner. Benefits of installing an undercarriage shield: 1. Anti-corrosion: Rust on cars usually starts from the bottom plate, and rust spots can appear on the side beams of cars that have been driven for two or three years; 2. Anti-stone impact: Small stones splashed during driving can damage the undercarriage; 3. Anti-vibration: The engine and wheels are fixed to the car's undercarriage, and their vibrations resonate with the bottom plate. An undercarriage shield can reduce some of this resonance; 4. Anti-scraping: When the bottom is scraped by road protrusions, the undercarriage shield can mitigate the damage caused by the protrusions to the undercarriage.

What is the process for downgrading a driver's license on 12123?

Open the fuel tank switch to release air from the fuel line, and set the speed control handle (throttle) to the maximum position. Align the end of the crank handle with the cylindrical pin and spiral groove on the starting shaft, and simultaneously move the decompression lever to the decompression position. Forcefully rotate the crank handle to turn the crankshaft. When the crankshaft speed reaches a sufficiently high level, quickly return the decompression lever to the non-decompression position. Continue to forcefully rotate the crankshaft until the diesel engine ignites. Diesel engines are the most widely used power source in agriculture, with most agricultural machinery relying on diesel engines for operation.
