Australian flathead questions

[Aussie54cussy]

Hi guys,

Hoping someone can shed some light on if my car is 6volt or 12v, and positive earth or negative earth - sounds easy but nothing is making sense.

First, my car is an Australian 1954 customline - these were built in Australian from Canadian knock down kits and run a mercury flathead in the standard 54 body. Seems like there were no consistent specs with these cars - it's like they were made from left over parts. The info I can find says they were either 6volt positive earth or 12v neg earth.

Now my car makes no sense. Globes are all 6v. But the coil is set up negative earth and has what I assume is a balance resistor attached to it - but if it's had a 12v conversion then how can it have 6v globes, and if it's still 6v then how can it be 6v neg earth?

And the Lucas regulator has no marking to help.

Any info would be very much appreciated

Thanks in advance
