while driving my car stalls and voltage gauge drops
When the vehicle is stationary, the voltage shows the terminal voltage of the battery, which is the no-load voltage without load. After the car is running, the battery will carry the load. At the same time, the battery, wires and other ballast voltage stabilizing elements will also be divided. Then the voltage at the load end will be insufficient and will drop. Moreover, the higher the speed, the greater the current output by the battery, the higher the apportioned voltage of the invalid part and the lower the voltage display.
The characteristics and general rules of automobile line wiring are as follows: generally, single line system, parallel connection of electrical equipment, negative grounding, lines are distinguished by lines and numbers with different colors, and divided into several trunk lines centered on the ignition switch. Battery positive wire: lead directly from the battery to the fuse box, or lead directly from the battery positive wire to the positive terminal of the starter, and then lead the thinner positive wire to other circuits. Ignition, instrument and indicator wires: the circuit can only be connected through the car key. Special line: electrical appliances that need to be connected no matter the engine works, such as radio and cassette player, cigarette lighter, etc., are powered by a separate gear set by the ignition switch.
While driving my car stalls and voltage gauge drops , it may be that the performance of the battery has deteriorated. Generally speaking, the internal resistance has become larger or the capacity is insufficient. Replace or maintain the battery to solve the problem.
The fuel with high elevation and qualified quality shall be used. It is possible that the quality of the oil you added is not up to the standard, and there is too much glue and grease, which blocks the oil circuit and impedes the oil attack. Due to too much dust in the air, there is a lot of dirt deposited at the valve core of idle motor and throttle seat when the engine is running. When the dirt accumulates too much, the engine will have low idle speed, poor idle stability, and idle flameout when driving. The car suddenly stalled while driving, the oil circuit failed, the gasoline pump was damaged, the oil pipe was broken, the oil inlet of the carburetor was blocked, and the oil tank was out of oil. Device failure, this problem is generally ignition coil, capacitor, electronic ignition module. It starts at the beginning, turns off after a while, and then there is no voltage.
What to do when the car suddenly stalls:
1. After the engine suddenly stalls during driving, the driver should turn on the hazard warning flash lamp, slow down the vehicle to the right side and pull over by relying on inertia, place warning signs behind the vehicle according to regulations, and then find out the cause.
2. Pull over immediately, make an emergency stop, and turn on the double flash. When controlling the vehicle to stop at the roadside, you need to pay extra attention to controlling the steering wheel. First check the problem of the vehicle, and then decide to contact the police or maintenance personnel according to the situation.
