Battery draining fast

I just bought my daughter a 65 Barracuda was transported from Sacramento to Los Angeles . Off the truck it started up with some hesitation but ran . Parked it and woke daughter up she drove it . The next day it was what I thought flooding . Did research and replaced resistor ballast and she started right up . Took most of the connection apart cleaned and replaced . Now the battery is draining really quick . I tested the alternator and its hot with the keys out of ignition at the post . Any suggestions

Thanks Bud27
