voltage gauge not working alt still charging
If the voltage gauge pointer no working stays at the 0 position,but alt still charging , it means that the charging circuit is not connected. Check which part of the circuit has a problem and remove the fault. If the current is stable at a certain value during charging , it is normal , indicating that it is charging , because charging takes a long time to accumulate , and the voltmeter will not be moving all the time .
When the car battery is charged , the current pointer of the charger does not move. There are two most common possibilities : first , the battery is fully charged , so in order to prevent overcharging , the charger automatically enters the "trickle charging" mode , that is , the charging current is very small and close to zero, so the pointer of the ammeter does not move . Immobility is normal . It shows that the charger is better, constant current charging. Another possibility is that the charging circuit is not connected , which needs to find out whether the switch is not connected or the circuit is disconnected .
Generally , the lack of battery power of the car is a sign . For example , when the car is in neutral or stops at a red light when driving at night, the light will be significantly dimmed , which indicates that the service life of the battery is coming to an end . Because the neutral gear is the idle running of the engine , which is not enough to provide the power of night light . At this time , it is basically powered by the battery. When the service life of the battery is almost over , it is not enough to provide sufficient lighting power , so the light will be dimmed. Or when starting the car , I feel obvious lack of ignition power, and the speed of ignition is not as good as before . Turn on the engine . If the speed is normal and the light is slightly dimmed , it still has enough brightness , indicating that the battery is good and fully charged. If the engine appears weak and the light becomes very dark, it indicates that the battery is over discharged and should be charged immediately.
