Obviously an amp-clamp is the way to measure the wires individually, wonder if the
parts stores have them to loan.

I probably should have started a new thread about the battery dying overnight.

After sleeping on it, I'm guessing that an always hot wire is pinched before the
fuse since pulling fuses didn't cure the high draw. Perhaps it has something to
do with the smashed door - we should replace it ASAP.

It would be great to have a wiring harness that highlights all the always on wiring for just
this sort of problem.
