Miller headlight switch
« on: 15 Jun 2014 at 01:44 »
I have a Douglas Handbook 600 c.c.(Side Valve) MOTORCYCLE      My bike is E/29 Model
I am trying to wire the headlight switch and found a contradiction in the book.
On page 40 the diagram shows battery to terminal 2 and dynamo to terminal 3.
On page 41 the diagram shows battery to terminal 3 and dynamo to terminal 2.
A previous owner has had it apart and put it together wrong.  Help!!!!!

The illustration on page 40 is "diagrammatic", and is more of a schematic than an verbatim view of the headlamp switch. However since it shows and describes the function of the switch, it should be relatively straight forward to wire up your switch, regardless of which terminal is numbered what. For example, the battery terminal has to be between the cutout (dyno) and half charge resistor terminal. Thus so it can be spanned by the same contact segment from the Charge, Low, and High positions of the switch. A second segment then takes care of making the connections to the appropriate lamp terminals.

If I look at the illustration on my photocopy of the E29 handbook for page 41, it shows the battery connected to terminal 2, and the cutout/dyno to terminal 3 (assuming a counter-clockwise ordering). This is the reverse of what you are seeing in your copy.
