Mercedes-Benz Smart starts without response, reporting that the generator is not excited.

Mercedes-Benz Smart didn't respond when it started. The reason why the generator is not excited is that.

1, battery voltage is too low: you can turn on headlights and some electrical equipment. When starting, check whether the instrument and indoor lighting are obviously dimmed. Confirm that it darkens, indicating that the battery voltage is not enough to drive the engine to reach the starting speed.

2. Too much carbon deposit in the intake pipe: too much carbon deposit will reduce the power, accompanied by a certain degree of fuel consumption increase. This is because when obtaining the same power as before carbon deposition, it is necessary to increase the throttle opening and the corresponding fuel supply. Carbon deposition in the intake port will affect the normal intake of the engine and hinder the intake, resulting in insufficient intake of the engine. When the air intake of the engine is insufficient, the output power of the engine will be unstable. Remove the intake pipe of the car, and use special tools to remove carbon deposits, or use cleaning agents to remove carbon deposits accumulated in the intake pipe.
