Battery drain

[A.P.]

Hi, to all. My truck seems to have a short somewhere, my battery dies after I let sit for week. I disconnected the battery and put a multimeter in series between the battery cable and battery. With the key off, I get a 3.4mA current drain. I removed all the fuses and nothing changes. But if I disconnect the two pin connector on the alternator, the current drops down to zero. I have an alternator with internal regulator, thats been in my truck for over 3 years. My question is, is a 3.4mA drain enough to drain a battery in one week? For those who have an alternator with internal regulator, have you measured the amount of current drain while the key is off? If you have, what is the drain amount? Thanks for any info. you all can provide.
