Getting a desulfator will bring back a battery if it's not too far gone and the internal cells aren't dead.

quick update ... when first attaching amp meter draw is .28 amps, after 50-60 seconds it drops to .058 amps. The last addition prior to battery issue was an interior dimming mirror w/ compass ... I'll pop that fuse and see if I get a drop. Garage thinks it may just be a shorting battery plate ... battery would still test fine but there would be a steady discharge. Looks like battery time.

Quick update : My wife noticed that the console gear select lamp was not on. Opened console replaced fried bulb. It would not light. Unable to determine fuse by looking at the owners manual. Thought I'd check all lamps / switches. To my surprise, the lamp lit after I played with the power seats. Out of curiosity, I rechecked the parasitic draw. It is now .045 amps ... before it was .058 amps (after 50 seconds). Held off on battery replacement because after a couple of charges it seems to be holding the charge. For awhile I had it on a quick disconnect but it's been connected the last few nights with no appreciable loss.
