    2003 Escalade - Battery Light

    Red battery light in the upper right hand area of dash stays slightly illuminated when the engine is either on/off. The light will become brighter when more accessories are turned on. Battery is new & the alt is putting out the correct charge. Any idea what the problem might be? Thanks.

    Re: 2003 Escalade - Battery Light

    I had this issue until last week. My friend owns a repair shop for large/heavy duty trucks and is working on an oil leak for me. While there I told him about the battery light being always on and all he did was plug in a scan tool and turn it off. If the other suggestions dont work out, maybe give this a try.
