Why does the battery light come on when changing the FAW Crown alternator?

1. The battery itself fails, such as battery drain, battery failure, etc. The solution is to use a multimeter to check the battery voltage. If the voltage is low, recharge and restore it. If the battery fails, replace it.

2. The battery terminals are loose or oxidized, and poor contact will also cause the battery light to illuminate. The solution is to clean and tighten the battery wiring.

3. It is not easy to detect when the car battery light is on, so you need to check the car regularly. Don't rush to drive after starting the car. Check if all indicators are working normally, especially before traveling to avoid unnecessary problems.

Car battery precautions:

< p>1. Before theUsers install a new battery, if the battery brands and models are inconsistent, they should compare the dimensions and terminal positions of the new and old batteries, and carefully check the battery capacity and current parameters of the battery. cold start. Especially in the northern winter, if the cold starting current does not match, it may cause difficulty starting the vehicle.

2. If conditions permit, a battery tester should be used to test after some batteries have been stored for a long time, although the voltage between the positive and negative electrodes is greater than 12V, the actual capacity. is not enough, this is called The battery needs to be charged. It should be noted that measurement should be carried out when the ambient temperature is above 0, and charging should be carried out when the ambient temperature is aboveto 5.

3. Place the new battery in the installation position and secure it. For batteries with breather tube, remember to remove the breather tube connector from the old battery and install it on the new battery. For lead-acid batteries, pay attention that the tilt angle of the battery does not exceed 30° during installation.
