You need a meter with ohms on it and a beeper or light for continuity testing.
Check for continuity, the wire between the coil and points, then check that the points are working properly, actually springing shut and opening with the correct gap (14 - 16 thou or .35 - .4 mm new money).
With the points closed, with the ignition turned on, pull them open and look for a little spark, if there is a big splashy spark, the condenser is duff.
If that checks out ok, do a resistance test on the coil, with the coil disconnected from everything (preferably on the bench) put an ohm meter on the two small terminals, ( the primary windings), make a note of the readings, then connect between the small terminal and the plug wire hole, (the secondary windings), make a note of these.
Unfortunately, I don't know what the exact readings should be, but as a rule of thumb, the primary windings want to be between .7 to 1.7 ohms, the secondary windings should be between 7,500 to 10,500 ohms.
The correct readings are important and should be somewhere on the interweb or a better brain than mine will be along shortly to tell us, but if you cannot get any readings on either winding, then it will prove that is the problem.
Sorry it's a bit long winded, but I hope it helps.
