If the points are shorted, the - terminal won't glow-the current all
goes to ground. If the - terminal glows, the - circuit is open.

How does a terminal glow?

Rob

The test lamp ON the terminal.....tap, tap, tap

So, if the points are not shorted or closed, and the OP is getting ~12
volts with a test lamp at the (+) & (-) terminals of the coil, where is
the ground/negative return for this circuit?

Rob

points closed completes the circuit.

Right, So, if the points are not shorted or closed, and the OP is
getting ~12 volts with a test lamp at the (+) & (-) terminals of the
coil, where is the ground/negative return for this circuit?

The OP also says his "hot" circuit does not continue across the points,
which would indicates the points are not closing.

Rob

There isn't a ground return. That's why he reads the same voltage
everywhere. He is reading the total circuit voltage across an open
circuit.The points must not be set right or the contacts are contaminated. I
think we are saying the same thing different ways.
