The dashboard doesn t show voltage? What s going on with a car dashboard running out of electricity?

It must be that a cable on the dashboard is broken, or the digital tube is broken.

Summary. Hello, there is no power in the car dashboard, check the following places, 1The battery is insufficient, 2, there is a problem with the ignition switch or a start, 3, the anti-theft verification is not passed, 4, the meter will not light up due to the problem of insurance power supply, 5The meter itself is damaged.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, the car hole does the dashboard without electricity, check the following places, 1The battery is insufficient, 2, there is a problem with the ignition switch or a start, 3, the anti-theft inspection certificate is not passed, 4, the meter will not be lit due to the problem of insurance power supply, 5The tremor watch itself is damaged.

Hello dear! Thank you for waiting, if the battery indicator is not displayed on the dashboard now, then there are three main reasons to consider. The first aspect to consider is that the regulator of the generator is damaged, like this regulator has a control loop with an indicator light inside, if the regulator is damaged and there is no circuit, then it will not be lit.

The second aspect to consider is that the light on your meter is broken before searching, like this meter has an indicator light inside is a bulb or wick, this will also be broken, after the break will not be lit. The third aspect is to consider the line from the generator to the instrument, there is a short circuit or open circuit, which needs to focus on checking the middle line conduction. Kiss!

If it refers to a car battery, then there are several main reasons for the low battery voltage after starting:

1. The car has been idle for a long time, resulting in the battery being fed due to self-discharge;

2. Frequent start of the vehicle, resulting in an increase in battery power consumption;

3. The driving distance is short, resulting in the power consumed by the battery cannot be replenished in time;

4. The battery is damaged.

Solution: 1. Start the vehicle, increase the throttle slightly, and charge the car battery;

2. Use a special charger to charge the battery;

3. Replace the battery.

Hello, I am happy to answer for you Your car master exclusive technician Concentrate on your heart and sincerely answer your car questions, find solutions and methods for you to ask questions, the car instrument prompts that the battery voltage is too low, to see clearly whether it is the remote control battery or just a simple battery voltage is too low. If it only prompts that the battery voltage is too low, you need to check whether the battery power is too low, if the battery is too low, you need to run more, or use the battery charger to charge the battery and check the battery status, if the battery is to change the battery, you need to replace the battery, if the display needs to be charged, you can charge the battery.

short circuit in ammeter;

Or the electric appliances connected in parallel with the voltmeter are open, and at this time, the large resistance (internal resistance of the voltmeter) is connected in series in the circuit where the ammeter is located, so that the current is too small, and the ammeter does not display the number clearly.

A normal current indication indicates that the main slag circuit is the path, and "voltmeter no indication" indicates that no current passes through the voltmeter. The cause of the failure may be:

Damaged voltmeter;

Poor contact of voltmeter;

Electrical appliances connected in parallel to the voltmeter are short-circuited. Quietly.

After the car battery is dead, the battery icon in the dashboard will continue to flash into an alarm state, reminding the owner that the battery is about to run out. The battery core icon is usually square with plus or minus signs indicating the positive and negative poles.

The dashboard is chaotic and abnormal.

There is also a situation where the dashboard display is abnormal, such as the display is dim and dull, and the black screen of the dashboard may also be caused by a serious power failure.

Battery observation holes.

In addition, if it cannot be judged by the instrument panel, it can be distinguished by the color of the observation hole of the electric alarm pool. Generally, it can be considered green to the naked eye, indicating that the battery is fully charged, yellow means that the battery is low, and black means that the battery is seriously dead. For different types of batteries, the color of the observation hole tip is slightly different.

For details, please refer to the manufacturer's official website.

Learn about dashboard alarm icons.

The instrument panel is an important display window for the functional status of the car. In the update and iteration of the entire smart car, the dashboard tends to be more refined. Observing and grasping the meaning of various icons in the dashboard helps the owner to drive the car better and greatly reduces the obstacles to the car's condition.
