If there's a load on the battery even when not running (say a short), would
the battery read lower?

Car batteries are considered DEAD at 11.8 volts or something like that.
excuse me, they are considered to have 0% charge.

If there's a short in the system, maybe disconnect the red lead and put your
multimeter in series (black lead on the red wire and the red wire on the +
battery post)...be sure to set the tester for current (amperage), set it to
a high scale so you odn't blow your meter.
If there's a short draining your battery, you would see current flowing (+
or -; not sure if I got your leads in the right order). don't forget there
will be a small amount of flow for your computer/radio or anything else that
would hold a memory!

Thanks for the suggestion, SB. That remind me a few weeks back, I can't turn
off the light under the hood. Even I close the hood completely, the light is
still on. I remove the light bulb since I don't use it anyway. Is that short
you talk about? Can that (without light bulb) still drain the battery? Thanks.
