Battery light remains on

Hi,

Always check the belt first to make sure it is tight. However, if it is loose enough for the alternator not to turn, chances are you would hear it.

This sounds like it is related to the alternator itself. First, I attached the wiring schematic for the charging system below as a reference. Here is what I need you to do:

Before starting it in the morning is when we need to test the alternator. we need to check the voltage output from the alternator when first started. All you will need is a voltmeter or a multimeter.

Follow the directions in this link and let me know the results:

Let me know both the battery voltage with the engine off and then the voltage when the engine first starts with the alt-light on.

Take care,

Joe

See pics below Note: The schematic was one page long. However, I had to cut it in half to make it readable for you. I did overlap them so you can follow from one to the next.

Problem solved after voltage test and confirm that the alternator was faulty.

Hi,

Thanks for the update. I had a feeling the alternator was the issue. Regardless, good job and I'm glad you got it fixed.

Take care of yourself and feel free to come back anytime in the future if you have questions. You are always welcome here.
