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.

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.
