If one side is connected to  battery positive and the other side to the moving 'arm' of the points, the lamp should light whenever the points are closed. Touch the wire to ground to check the bulb . If it lights up,  connected between positive and ground,  then it would suggest that your points are badly corroded or not closing. Also possible is that the points backplate is not grounded properly or your test lamp is an LED , which will only work when connected the correct way round - Red to positive,  Black to ground.
