I have the same car I had the same problem.If you have the correct battery for your car with the same problem you have a short or positive ground in your dash/electric fuel pump/fuse box also be carefull of how you take the key from the ignition and if they're old replace them.

The FuseLink is blown. It is a 100 AMP in-line fuse on the red wire from the alternator.

The first thing I would do is remove the alternater and take it to an auto parts store and have them check it. If the alternater is working good, then check the belts are routed and have the right tension. Either of these can keep the battery from charging. It's very common that a rebuilt alternater isn't working properly. If all these things are correct, check the live wire to the alternater is live. If it isn't alive you have problems in the wiring and I would take it to a mechanic.
