No my battery is dying still like something is not connected the lights on the dash turn off rite after they all come on when I try to start it again the battery is completely dead but starts rite up no problem with a jump and stays on for about a minute or two after taking off the jumper cables it will stay on for about two minutes and do the same thing lights will come on and then they all turn off car starts to die but if reconnect the cables before it dies it runs normal and all the lights come back on

I'm having a hard time following your posts and understanding exactly what is transpiring.

Sounds to me like your new alternator is a dud. Wouldn't be the first time we've seen this. Can you get the car to run on it's own for 1 minute without being hooked up to jumper cables? This may require a new battery if your existing battery is toast and not rechargeable. Grab a multimeter and look at the voltage at the battery terminals while the car is running. It should be pretty consistent and fluctuate very little and be in the 13v to 14v range. Then watch the multimeter over the course of the minute or two that it runs on its own. If the voltage keeps dropping and dropping, that's a sure sign it's your alternator.

Also, check the fuses both under the hood and in the car.
