Dipping Headlamp wiring - David.H - 14-05-2018

Does anyone have a wiring diagram for the dipping circuit for my AG tourer. I have now established it has R47 35/32 lamps with original Lucas Graves reflectors (which I eventually will get re-silvered in Birmingham) I have some Bosch bulbs somewhere, I will see if they fit the bulb holders (which do take BPF bulbs if all else fails)
I particularly need to know how to wire up the 9/CS dip switch (3 Terminals) to the terminal block on the bulkhead & thence to the light switch and on to the Head & sidelights. I can probably work out the tail light wiring.... Advice on wire gauges will be helpful too.
Were there any particular colours? the remains of the wiring to the dip switch are not much help. the "top" wire is white! Were they still in "armoured" cable in early 1932?
The wiring at the moment looks like the trade test (failed) of an apprentice electrician in week two of training! how not to do it!

Hopefully there is an RN wiring diagram attached. The wire from the light switch H terminal goes to the dip switch terminal which has the switch lever on, the other two terminals are dip and main which ever way suits you, I arrange it with the lever up is main and down dip. I don't think the wire to the dip switch was armoured, I use some 3 core mains flex.

Check the A7CA Archive to see if the handbook is available to view.

Just checked- Handbook 715D is available with the wiring diagram on page 36-

Fantastic! THAT even I can follow.
Thanks so much.
I have removed all the old wires & the body is 75% done, so this is a great help.
The car is a bit of a special...1932 AG original steel body (chummy) SWB tourer, modified with 4 speed box, Nippy head etc (not crankcase, sadly) hydraulic brakes & an interesting history...Hong Kong, California, Ohio....
