    Is your belt properly tightened on the Alt?
    Yes, this sounds like your battery.
    Just go to Dangerzone and get it tested.

    yea well i replaced the alternator cause it just started doing the same thing
    when i rebuilt the motor the car sat for a 2 weeks and the battery was completly dead
    i had them test the old alternator and it was only putting out 12 volts
    so i think the battery is shot
    anyone have anything like this happen to them before

    Yeppers. Had my battery disconnected for about 3 weeks once while putting my car back together. I put it together hooked the battery up and had to jump the car to get it to start. Afterwards I was driving to a buddys house and the same exact thing happened to me. Replaced my alternator(free bec of the Auto Zone warranty ROFL) and had them do a quick charge on my battery. Good as new now :thumb:

    Check your alt. fuse and see if it needs to be replaced.

    Make sure the the power steering pump bracket is tightened all the way. I experienced the same symptoms and it ended up being because the power steering pump was loose and was hitting the alternator, causing the car to lose all power. Just another idea of what it could be.

    EDIT: Did you take it down the road after you tightened everything down, to see if it is still losing power? From your posts it really seems like it's grounding out somewhere.

    Get your "new" alt. tested and most likely, replaced.

    Make sure the battery + terminal isn't grounding to the hood or strut bar. Bolt it down, and use a cover over the + teminal.

    I agree I would also take back the battery and get it tested. Ive bought batteries from Auto Zone before brought them home and they didnt work. I take them back and have them check and go figure its a bad battery. I havent had trouble with any of my Auto Zone alternators though. Mine hold 14.3-14.5 volts cruising and 14.1 at idle :thumb:

    Make sure your battery terminals are clean. Use some baking soda and water on the terminals to clean them off. Replace the cable's end if needed to make a good connection. Make sure your ground cable going down to the transmission bolt is tight and clean. Cleanliness and solid connections are the key to success.

    I had the same problem. The battery terminals looked great all together. Then, I took off the terminal and it was all corroded. So, I cleaned it up and put it back together and I had no more problems.

    Also, feel the terminals if they are warm or hot to the touch then it's having a hard time getting current through that terminal and that's where your problem lies.
