6 volt to 12 volt austin 7

[Ian Williams]

I am another 6V exponent, like Martin I do not see the point of going 12V, the only failing of a 6V system is it requires all connections to be in good condition, any resistance in joints or through undersized cable will have a greater effect. Think of it like a fluid flowing in a pipe, if the pipe is small it will resist flow, if there are poor joints the pipe will leak, either way you will not get so much out the other end. 12V can be thought of as increasing the pressure in the system to over come resistance, only really necessary if your 6V system is in poor condition. Much simplified explanation but there is no need to complicate and confuse matters with technicalities. The old argument that 12V allowed you to use larger wattage bulbs to gain brighter headlights is, as already mentioned a thing of the past
