Coils and ballast resistors
Discussion
Due to swopping an engine I have a mix of old a new parts including the coil that goes with the engine but I have no idea is it's 6v or 12v; if it's 6 I need to add a ballast resistor, so does anyone know if it's possible to tell if the coil is 6 or 12 v as there is no label on it!
(Please don't ask what the cars are ;-) one is 1951 and the other 1973, and it's too complicated to try and explain why what and how, but if you know the answer to the question it would help!)
Having typed this I think it might be easier to just buy a 12v coil and have done with it, but I'lll see if someone answers!
Cheers
