If more than a tiny fraction of a volt can be measured at the points, clean or replace them.
THE POINTS ARE A GROUND. A GROUND MEANS ZERO VOLTS!
When the points are open, you will read full battery voltage at the side of the distributor, regardless of what the coil winding resistance and/or any extra resistors which happen to be in the circuit.
