Can you use on of those CDI systems that used to clip onto the coil? Can't think who used to make them but they didn't use the coil, you take the points out and put an optical chopper in instead.

I think that only works on 12v and not on 6v, but I could be wrong

Yep Alan, they are the ones! Must be a few years since they were sold though what with most cars these days having electronic ignition as standard.
Didn't know they wouldn't work on 6v though.

thanks for the info ,I know what you mean, but I don't think they will work on 6v systems, but I'll look into it.
I've not seen them around for some time know,but I did see reports that they worked well.

have a look an old VW coil. 6v electrics but I am not sure about the pos earth bit.

My first car was a 1959 sit-up-and-beg Ford Popular with a 3 speed crash gearbox, cable operated drum brakes and yes, 6 volt positive earth electrics.

I would have thought that you could source a coil from something like this - cos I think your best bet is a temporary fix involving taking the original coil out of circuit and using another one in it's place. Should be easy enough to modify the primary connections shouldn't it?
