Well, if your not joking, here's the deal with
electricity.  You are going to always have a voltage
across that big red wire, and anything else that's
grounded in the car.  That's good.  The voltage
doesn't drain any power, you want to measure current.
 If you are testing for battery drain, take the lead
off the battery, and put your meter in between the
lead and the battery post.  Make sure it is set to
milliamps.  You should see a very small amount of
drain just to keep stuff like the clock and radio
settings.
