With the ignition on, crank the engine. if the light flashes, the points are working. if not, and the light stays on, the points are not closing, or the connection is open to the points. If it stays off, the points (or lead to the points) are closed, not opening, shorted to ground, or the lead where it passes through is shorted to ground.
