I also leave the X unlocked because last time when the battery got so low, the alarm starting going off at 3am waking everyone in a panic...

I bought the perfect fuse based ammeter from harbor freight. You pull a fuse plug it Into the fuse socket and put the fuse into the ammeter. Digital readout shows the amperage and can handle at least 30a. I don't have time to track down a link but from my description you'll know when you find it. I've used a few times to track down parasitic drain but it's only full size fuses I'd like to get similar for mini fuses.
