You really need to read how a dynamo/contact breaker/regulator works. There could be several reasons for the light not going out, from dynamo not giving an output to fault in cut-out box.
The cut out closes when the current from a charging dynamo runs through the cut out coil enough to create enough magnetism to attract the metal bit attached to the points to pull them closed. The adjustment of the points is quite critical.
It does sound though that your dynamo is not working.
A good read is the Lucas technical service overseas correspondence course http://mgaguru.com/mgtech/books/lts_otcc.htm
That should get you looking in the right area.
