At idle the charging system isn't doing anything so the only thing 
you're checking is the battery voltage which is slowly running 
down. What you need to test is the Charging System regulating 
voltage which you can only measure at a high enough rpm to get 
the output voltage up high enough to regulate.

If you watch what the voltage does as you up the rpm you will see 
that it rises slowly and then levels off at some value. That value is 
the regulating voltage. So just watch for it to level off, then measure.
