I have a 1969 Brum Scott. It did not have a Zenner diode fitted. Just an unregulated 6 volt system.
Your machine should be running a 12v system driven by an alternator off the L/H side of the crank , the drawing I have shows no voltage regulation device of any kind, strange but true !
If your running a 6v system using a dynamo, which is not standard for your year, then you will have a regulator box fitted to the machine
If you can clarify which charging system you have fitted I will help you sort out your query .
