    Took TV (2004 olds bravado) to Wal-Mart yesterday to have new tires installed. Have been working on replacing struts,ball joints and tie rods. Started in January, but stopped due to wife's illness. Car stayed on Jack stands until her death in July. On the way to Wal-Mart, the battery light came on. I had to charge the battery several times while the car was down for repairs, so I had Wal-Mart to in stall a new one. Now I have no headlights. Turn signals work, brake lights, etc, but no headlights. Also the battery light stays on even when the key is off. Anyone ever had this problem before. I am removing the alternator to have it checked.

    I had that happen with my Durango. It ended up a computer board. Replaced that and the lights all worked again. However, my remote for the locks no longer worked. Thought it just simply needed re-programmed, but it was another computer board. They wanted $600 for that and all it did was work the remote. I use the key instead.

    Try the headlight relay in the fuse box under the hood #46

    Might pull the battery cables. Cycle the key to insure no other surface charge and reconnect cables. Or yep, alternator is ready.

    Those vehicles have had issues with ignition switches... can cause some peculiar issues.

    Check some of the simple stuff above. Another thought is your lighting control module may need replaced if you have one in that vehicle.

    I'm betting alternator. I had an older blazer that had the alternator go twice.

    Had alternator checked, it's good. Reinstalled alternator and battery. Car starts fine, runs good, battery charging and lights now working, but battery light still stays on even when the key is off . It is not bright as when the ignition is first turned on, but glows dim.

    If I can get someone to help, I plan on pulling fuses until the light goes out and checking whatever is on that fuse.

    If the battery light is on with the key out I would suspect the ignition switch. Try wiggling the switch around a little and see if the light goes out.

    ^^Good advice here..

    So you have a voltage meter indicating a working alternator (~14v) AND a battery light indicator? Vehicles nowadays can do some weird stuff electrically with a low battery. Did they load test the battery? Just because the gauge shows 14v doesn't mean it's getting to the battery, or that the battery is accepting the charge.

    Good clean cables and clamps?
