Dear M;
1). Turn engine till points are open.
2). Connect a 'jump wire' from the + side of coil to the + side of battery.
3). If spark (jump wire) occurs, points are shorted. If none, go to step 4.
4). Pull the coil (HV) wire out of the distributor cap & place near ground.
5). Short the points with an old screwdriver. An (HV) spark should occur where the coil wire is near ground and @ the points (12V) also.
Good luck.
