I assume your freshly charged battery has been tested and is good. Following tblakes advice, make sure you disconnect the negative cable and put your ammeter between the negative post and the negative cable. For the battery to drop that fast, you have to have a major draw, like a dead shorted engine cooling fan, alternator, etc... When you get your ammeter hooked up, try unhooking the plug to the voltage regulator on the alternator first. If the draw goes away, the alternator is dead shorted internally.
