1998 blazer low voltage gauge but charging
The 1998 blazer battery cannot be charged properly due to insufficient and low charging of the generator. If the problem of the generator is eliminated (a larger specification can be replaced) , you can use a multimeter to measure the voltage between the output terminal from the generator to the positive electrode of the battery and the negative electrode of the battery. If the voltage is greater than 14V , it is normal . Then the wire from the generator to the positive electrode is aging , and another one can be connected. If it is lower than 14V , disassemble the generator to check the carbon brush or replace the generator .
If it is turned on every day , it means that the 1998 blazer generator is generating electricity. If it is not generating electricity , the electricity in the battery will be used up long ago. The normal power generation voltage is not lower than 13V . It is estimated that the power generation is not good, or the battery has no electricity. Another possibility is that there is leakage. I will tell you how to measure whether the generator generates electricity . You can use a flat head screwdriver to put it in front of the generator wheel, gently touch it , and slowly move it away . Feel if there is suction. In some cases, it is power generation. In the case of batteries , there are things to measure the batteries at the place where the batteries are sold. You can go to test them without money. For example, if you have condensation leakage, you can remove the negative electrode of the battery when you drive home at night , that is, separate the negative electrode from the battery. Remember, the black main negative electrode . You'd better go to the 4S store to check .
When the open 1998 blazer circuit voltage of the car battery is lower than 12.2v and the load voltage is lower than 9.5v , it will be difficult to start the car . The car owner needs to check the car battery during daily use . Check through the observation hole on the battery. If the observation hole shows black , it means charging is required . If it is green , it means good . If it is white , it means insufficient electrolyte.
