As soon as Wuling Glory stepped on the gas pedal, there was a relay pull-in sound.

What you want to ask is what if Wuling Glory steps on the gas pedal and there is a relay pull-in sound? Check the current and voltage. According to the inquiry, Pacific Auto Network shows that.

1, check whether the battery voltage is too low, turn on the headlights and some electrical equipment, and confirm whether the instrument changes in light and shade during startup. If it is confirmed to be dark, the battery voltage is insufficient. When the battery power supply is insufficient, it will drive the engine to reach the starting speed, and the car can't start, but the magnetic bag and the starting relay are repeatedly pulled in, resulting in pull-in noise.

2. Check whether there is an open circuit in the circuit, which leads to the low output voltage of the neutral point of the alternator when the engine is running at a medium speed, and can not reach the action voltage of the starting combination relay, so that the contacts of the starting combination relay are constantly opened and closed, and a sucking sound is made.

3. Check whether there is carbon deposit in the throttle. There is too much carbon deposit in the throttle and idle motor, which makes the mixture of the engine fail to reach the required air-fuel ratio, resulting in the failure to start the vehicle. Repeatedly sucking the magnetic bag and starting the relay will make a sucking sound.
