3.2 milliamps. I have a very weak charger from a lawn mower, but the battery did get to 11.25V and rapidly fell almost a whole volt when hooked up for a few minutes. Would not crank at all. Will give it overnight to charge and see if any crank.

I'll do the fuse tests, and a diode test once I get it running, but so far no explanation. I don't see how I could have shorted something in the removal and replacement of the fuse box, or how all those disconnects dangling for 2 days would have drained the battery. Which is not that old by the way.

Not getting any crank. I'm still thinking starter or ignition short, but with no parasitic draw? That's my topic for research this evening.
