It can be done with a pencil lead but a polarity tester like the one Nu-Rex makes is a bit easier to use. Ford likely had a problem with polarity in the early days of the model A before that service bulletin came out in 1929 to change the coil wires around. It won't run as good if the polarity is off.

The SparkLite is a very handy tool. I was skeptical when I first bought it, but I have used it frequently.
