Q: Not starting, battery drains

new battery,new starter,alternator tests good,fusible link intact,cables good,terminal bolts new, clean ,tight,accessory belt good ,tight.
My car has an automatic transmission.

The alternator may test good but may be cause of draw on battery. You will need to have the battery draw isolated by checking the circuits until the draw is found. This can only be done by isolating circuits. I recommend having a certified technician, like one from YourMechanic, perform these checks for you firsthand and pinpoint your starting issue.
