Hi All,

The cable is supplied by digital speedos. http://www.digital-speedos.co.uk/bsa--triumph-cable-drive-adapter-1123-p.asp.

Wouldn't that be just the job to drive a digital tacho if your "A" has a drive from the oil pump ?? *bright idea*

I was wondering that but I suspect the tacho  needs a different type of pulse. I suppose you could drive two speedos and read one as a tacho!
