Stop in for a cup of coffee

When you apply a resistance check on a capacitor, the needle should swing over. Analog meter with a power source like AA or 9V battery.
Otherwise you need a meter that does capacitance.

Typically its power source to coil - in your case maybe coil negative if was for a positve ground application, then to the points. When the points close, current should flow through the coil primary windings to ground.

Testing condensers without a dedicated tester is impossible. Analog multi-meter on ohms scale test one way, then reverse leads. Needle will bump if its not open or shorted.
Depending on meter, battery size matters. 9 volt powered ones are better.
Or just holding on to wire,tag it across 12 volts then hand it to your wife. If she gets a snap then its good...

And not knowing the microfarads needed for your particular application, testing is pointless.
An engine will run without a condenser, just not very well. value is important, as it prolongs the life of the contact set.
It’s a 9 volt analog. Not even getting spark at all. I’m getting 12 volts to the positive side of the coil. Not getting a thing at the condenser. Thinking about taking it out and sending it to hoppy.
