Should Points Be Sparking?

Points shouldn't spark when the engine is running but they might while you're working on it. The points are the grounding circuit for the primary side of the ignition coil. If the secondary side is not completed - spark plugs in and hooked up, (make sure the plug leads are good) you can get a spark across the points.

What causes points to spark?

the spark at the point gap is caused by the 'back-emf' of the ignition coil. the system works like this: 1) points close , current flows through points energising the ignition coil via it's primary winding. 2) voltage builds across ignition coil, which creats a magnetic field.

Why is there no spark at points?

If no spark is visible, check to see if the points or wires are shorting to ground either at the points or at the primary terminal screw going through the housing. ... Last but not least, there could be a problem with the coil itself or the coil wire going back to the cap.
