>>The contact points are switching the coil wire to ground.  With ignition
on, when points are open there will be power on the wire from coil to
distributor.  When points are closed the wire is grounded and will have no
power, 0-volts, no light.

One of these is not like the other.  :-)
You can use a dwell meter if you don't have a test light.  With the points
closed, the meter will read 0 degrees of dwell, with the points open it
will read 90 degrees.
