    Default Battery gauge flickers when turn signals are being used. [Expired Topic]

    The gauge also goes down when the power windows are being operated, emergency flasher on, and when the ac is turned on. Any ideas? Thanks for your help.

    How much is it flickering? A small amount is ok, but if its going into the red each time, you are having a charging problem. Is it only happening at idle or does it happen while driving as well?

    It happens while driving as well. Not to mention when I shift to drive. Sometimes the windows will stop working...I think somehow it is all tied together. I have had the truck (95 Suburban) for almost 3 years and it has always done it. I just replaced the alternator last week and it is still doing it. I really appreciate your time.

    Sounds like a short.

    Has he done any rewiring lately?

    Check all grounds, especially the ones on the engine to the firewall.

    If it is a short, there should be fuses blowing. Having a bad ground will definately cause this type of behavior. I had problems just like this and more with my 93 a short while back, and there were several grounds that had been taken loose to replace te engine, but had never been put back.

    I looked and looked and looked for months before I finally took it to the dealer and paid them 150 bux to track down and fix the problem. Several ground wires later, all is fine!
