B_man_Al, Yes Al I am hearing what you say and its a trickey system for sure to arrive at what is a correct reading both in volts and current draw. The harder you rev the engine the lower the coil current draw and voltage reading. I usually check at idle speed and voltage can be about 3 volts and 2.5 amps current draw ballpark figures. Anyway when checking this I usually do tests with the engine stopped, points closed and then do the engine running test. With engine stopped test the longer the ignition is left on ,then the hotter the resistor becomes and higher resistance which alters all readings. Anyway enough of that and thanks for your comments. Regards, Kevin.
