It sounds like you have got a short circuit or fault somewhere draining power.

have you got a volt meter ? if so test the voltage on the battery then start it up and test it again , if the voltage is higher then the aulternator is ok , you know the batery is ok so if the aulternater is reading lower then get another one but check all conections first , if all is fine then suspect the starter motor.

thanks for the help. i think its the new alternator draining current, because the car is drawing 2.5 amps, when all is switched off but when i disconnect wire on the back of alternator it draws .03amps, the only worry i have is when i dissconnect alternator wire does this disconnect anything else that could cause this? I don't think i had a drain before i changed alternator

Faulty alternators can present a permanent power drain ... it could be the new one is goosed??
