battery dies but alternator is good

I posted a week ago that my battery dies, I took my alternator out and had it tested and its good. What could be wrong? Does something have a bad ground and its draining my battery? Just need some help!

Unless you've converted to a single wire, you might check the external regulator. Same thing happened to mine, alternator turned out OK but it wasn't charging.

Try disconnecting the negative cable from the battery. Put a test light between the negative cable and the negative post of the battery. See if the test light comes on. It should not light up unless you have a clock or a modern radio memory.
