No Spark, 77 Midget

Last week my 77 Midget stopped running at highway speeds.  I coasted
to the side and found that the car had no spark.  I did not have a
multi-meter (not sure if that would have helped) so I got towed home.

Last night I was poking around with a multi-meter and this is what I
found:

      1.  If the points are OPENED there still is a path to ground on
      the positive side of the coil.  I would think there should only
      be a path to ground if the points are closed.

      2.  I disconnected the white-black wire from the coil that that
      still had a path to ground (as verified by my ohm meter).

Am I looking at a short to ground somewhere between the coil and the
tach or somewhere further down the line?  Or is my line of reasoning
incorrect?

The coil has ~8 volts when the car is on (the system has a ballast
resistor).  Any ideas on what I should be seeing?

PS.  Haynes shows that the early 77 cars do not have a ballast
resistor, but car does and it was built in Feb of 77.  Go figure.
