Roughly speaking, you should have just about full continuity between the coil’s ground wire and the coil’s wire that attaches to the points. You should have maybe 5000 to 7000ish ohms between the coil’s ground wire and the spark plug terminal…..or if you have taken the coil off the mag plate, then where the coil wire would attach. There are exceptions to every rule; but for the most part, if a coil appears to be in good physical condition, it is probably going to work.
There are electrical brains on here that get deep into condensers; but what I have found is, yeah, yours are probably bad and if you can get new ones that will physically fit where the old ones were, they will probably work fine.
last but not least, you should have zero ohms (complete, 100% continuity) across the points, with the points closed and the coil NOT attached. If you even have ONE ohm, you have a problem. When the points are open, you should have infinite resistance.
Long live American manufacturing!
