Yes the FAQ is more accurate than simply checking the
resistance. The bad part is that a dwell meter is much more
expensive than a test light and does exactly the same result
on this test.
What you want to do is to remove the negative side of the coil
and attach it to your test light (possibly 22-50 watts bulb would
be better.) If you don't want to remove any wire then attach a
ground lead to the secondary port on the coil to prevent coil or
igniter damage.
