In any event, if you have a mystery battery drain like that and it isn't obvious, I'd recommend taking off the negative battery cable and put an ohmmeter between the disconnected negative cable and ground. It should read infinity, or very high, or open. If you get something less than 1,000 ohms, start looking for frayed wires, accessories left on, something. (That's for a negative ground system which is original)

If the battery fails and you have over 1,000 ohms, you have a bad battery.

On another note, draining a battery repeatedly will destroy it. Until the issue is figured out you should remove a battery cable when you park. Also put a trickle charger on the battery for at least a day or two after draining it.
Yes confusing because at first he said it was negative ground then changed it to positive ground.

Regardless I believe he has his answer, leaving the key on will drain the battery. As he said in the first post
