The alternator was just replaced. Now my car battery and brake light keeps lighting up on the dash. Sometimes if I touch my brake it will go away. Why is my car doing this?

Hello,

This could be a few things, but let's start with these first. Can you double check that the wires going from the alternator to the battery are clean, corrosion free, tight, and making good metal to metal contact? Next could make sure that your serpentine belt is tight and not off track. Here is a link below for you to go to:

I have also included in the diagrams down below a wiring diagram of your vehicle's charging circuit. Please go through these guides and check these systems out, and get back to us with what you are able to find out. We can go from there.

Thanks,
Alex
