"Other stuff"
Use your head here and THINK
The points are simply a switch to ground. If you stop the engine with points open, or BLOCK them open, the coil voltage on both terminals should be "same as battery"
With points closed, the coil power terminal should be "same as battery" but the points terminal should be VERY low.
So consider the circuit path from the coil points terminal.
1....The terminal end there at the coil to the wire. THAT can be bad in some cases, molded plastic/ rubber etc
2....The distributor primary wire can be broken open internally, and intermittent.
3.....The distributor primary wire can/ has and might SHORT at the grommet going through the distributor case
4.....If the path into the distributor is a feed through terminal and not a grommet, the insulating washers can be allowing a short, OR MOISTURE AND CORROSION in that assembly could be fouling things up
5.....The terminal/ insulator right at the points might be suspect.....shorting to ground or intermittent
6....MOST COMMON would be the points themselves are dirty/ greasy/ corroded and not making contact or INTERMITTENT
7....The breaker plate MUST be grounded. If the coil points terminal shows a lot of voltage / points closed, don't assume it's the points contacts......CHECK the breaker plate!!! Put your meter lead on the points ground mounting, and the other probe on the distributor CASE. If you show ANY voltage, investigate. The breaker plate MAY HAVE (or missing) a ground braid
