I am pretty sure I have a slow battery drain, as the battery retains more voltage longer when sitting pretty and disconnected than when plugged into the car. I lose about 0.5V overnight when plugged in...after a week, no start, obviously... I suspect stuff I did recently (gauges, Voltage reg) but that's not the issue (yet)... I followed common directions:

Set Multimeter to Amps, disconnect Neg cable from battery and run the Multimeter in series between the neg battery post and (-) cable (or do it all on the + side, same thing, just riskier). Observe Amps draw, and start pulling fuses until it the load drops, you've found your problem circuit... Easy in theory... There's even Youtube videos on this for Pete's sake...

Well my Multimeter reads a big fat 0.00, in Amps, milliamps, you name it. Never moves. I've got the leads in the right connectors per the MM screen itself... A low number, I can believe, but 0.00 seems like a wrong read to me ?

The MM is still fused and not broken as far as I can tell. It reads voltage and other stuff fine, fuses aren't melted... I went to an auto store to buy another one, but held off as really good ones are not cheap. The sales guy asked why I needed 2, I explained and he told me regular MMs were "useless" to do this... I needed either a load tester or a quality $$$ Fluke MM. I have seen several Youtube vids on this procedure with what appears to be crappier than mine "run of the mill" MMs... So what am I doing wrong ? Thanks !!
