Thanks for the responses; I am kind of weak with the volt meter, if I measure DC Milli-amps on the volt meter will that suffice as the ammeter?

Am I right in thinking that when a battery drains, its volt output is unaffected; only its available load (cranking amps) is. Correct? If this is true, then even a voltage leak would not cause a battery to go from 12v to 10v.
