The inductive (as sold by Snap-on; I'm sure that there are less-expensive ones available) or Hall-effect ammeters are used to measure the current drawn by the starter. As was mentioned, the current drawn with a 12-volt starter and battery should not be much above 200 amps.

Did you say how fast it cranks with the spark plugs removed?
