That can't be enough draw to cause any sort of significant drain on the battery. I also took out all the fuses one by one (those in the engine compartment and under the seat) and none had any effect on the amp readings. So now I'm really stumped ..... any thoughts anyone?

Based on your test, if that is the current draw, it is not enough to drain your battery in one weeks time. I know that you state in your post that you had the alternator checked out, but I would suggest that prior to re-installing it, you set you multimeter to the continuity setting, and touch one lead to the battery terminal of the alternator, and the other lead to the case of the alternator. If there is a strong continuity, then I would say that one or more of the diodes has failed. If you have already re-installed the alternator, I would suggest that you disconnect all wiring to the alternator, and then, using your meter, measure the current draw between the battery post of the alternator and the battery cable leading to it. If you have a higher current draw, your alternator is the culprit. Good luck
