batt gauge not showing voltage
1. The battery has an open circuit fault. The battery can be replaced.
2.Maybe the fuse is blown.
Precautions for the use of gauge instrument panel:
1.Regularly wipe the surface of each automobile instrument to prevent dust and oil from invading into the instrument and damaging the meter core. On the other hand, it is also convenient to observe the dynamics of the instrument pointer.
2.Master the performance of each instrument and the relationship between the instrument indication state and the working condition of relevant parts of the engine, so as to judge the working condition of the engine and find out the fault location and cause according to the instrument indication state.
Generally, when the key is turned to the start position, the vehicle will conduct pre start self-test, and then the lights on the instrument panel will go out one after another. Especially the battery lamp: if it is normal, it is on before ignition and will go out after ignition; If there is a problem, it will not light up directly when you unlock the key, or it will not go out after ignition. It is recommended to carry out detection in time to prevent anchoring on the way.
The voltage of the car is difficult to master. When charging, the voltage is more than 13V. When the power loss is below 11V, there is no fire at this time. Under normal circumstances, it will also drop below 11V during ignition. If 10V alarm is set, it will also alarm after ignition. The battery has a voltage stabilizing effect in the automobile circuit, and the voltage from the generator is about 15V. If it is output directly, it will burn electrical appliances. In many cases, the battery alarm light will light up after the generator breaks down, and the battery will not be charged.
When the car batt gauge is not showing voltage, there will be a symbol like a battery on the dashboard, with a plus sign and a minus sign on one side. The vehicle will charge the battery during driving. If the low battery symbol appears during long-term driving, the battery is damaged or can not be charged. The battery needs to be checked and replaced in time.
A variety of indicator lights or warning lights are made under the facial mask of modern automobile instrument panel, such as coolant level warning light, fuel volume indicator light, washer level indicator light, charging indicator light and so on.
