225 Slant no spark

It might not be the original resistor. Regardless, that is not your problem.

Please re- read what I posted.

In "start" (assuming the car wiring is OK) and using the key to crank the car, the ignition switch sends battery voltage DIRECTLY to the coil by means of the brown wire. You can see that wire going to the ballast resistor on one end.

What this means is, you can remove the ballast resistor and toss it in a nearby lake, and the car will fire for a split second while cranking the engine.

This in part is why my posting was as it is --- to try and find out what is going on
