    Intermittent Voltage Drop

    1996 Park Avenue, 190,000 miles.

    I am experiencing intermittent voltage drops. Sometimes the drop causes the battery light to come on. This has been going on for months. No problem with the car starting.

    I have changed the battery and the alternator as well as a speed sensor (trouble code).

    Mr. Goodwrentch can't figure it out. I know it is not the guage as the lights dim when the voltage drops.

    Any suggestions would be appreciated.

    Thank you.

    How do all the grounds look? Focus on the negative battery terminal and follow everywhere it goes. I'd remove the bolts, and clean the contact points with a wire brush.
