Yeah, all good advice Jim.  You should be able to read some small 
current from turning on the radio or parking lights or such.  power = 
volts * amps, so a parking light at like 5 watts should show about 0.4 
amps times however many there are.  If you're reading 0.0, something is 
not right.  Even a properly functioning car should have a tiny draw for 
the clock and other little stuff, though you will need to dial the meter 
way down to read it.
