You said that right...plus you'd need a hefty multimeter to measure amps from an alternator. The handheld ones are rated to 10amps before the fuse blows (or you hand fries which ever comes first).

It has to be more than 10 amps to handle the load of the lights, fan, defroster, wipers and least of all the engine ignition, fuel injection and charging systems all at the same time. My guess from this load would be @ 55 amps which is typical for a car without power windows.
