That would only let all of the analog smoke out of your test light!!
There are tests out there looking for specific values of resistance in ohms between the various coil wires and ground. These indicate whether you have broken wires in the coil or perhaps the enamel insulation on the wire is breaking down. These tests are usually done with the plug cap removed so that any resistance there is NOT part of the circuit under test.
The problem here is that every different part number for coils has different values for resistance which makes stating absolute values for any particular type of coil impossible. I have resistance values for my 70's Honda minibike engine coils but that will not help us here.
I will say this - most coils do not fail internally. Usually, it is a broken wire that can be fixed with a high tension wire splice kit. Or, the plug cap fails open with infinite resistance (due to trapped rusty water) on a continuity test on a multimeter - simply get a new plug cap.
I have also "repaired" coils by removing the plug cap and then nipping a quarter inch of the wire off and then reinstalling the cap. Rusty water can wick its way up the wire and kill the spark.
