Reply To: 6 to 12 volt conversion.

Kenneth,

If your Traction was originally 6V I assume it was not a Slough car and, being 1935, is almost certainly LHD Paris built.  Paris cars  (or those from any of the other Continental factory) were only ever built with a 6V system right through to 1956 so no 12V wiring diagrams exist.

Your car will have been built without indicators or brake lights and with only one rear light.  Nevertheless, a late 6V diagram ought to give you a starting point because, in general, the layout for a 12V conversion is likely to be quite similar to that of a 6V car.

I therefore suggest you start by consulting this excellent publication from the technical pages of this website ………………

However, when a car is converted there are often modifications incorporated into the new system which will differ from the basic “original” 6V wiring.  (I am aware some conversions require a system for stepping down to 6V to power certain components such as the wipers whilst others will incorporate an alternator).

Bonne chance!
