I have a 13 year old Roadsport, with five speed gearbox and mechanical speedo.
After several failures, mostly the nasty angle that takes the drive of the gearbox, but also two new speedos, I thought it would be better to upgrade to an electric speedo, but was in ignorance of the resulting difficulties.
I have drive sensor, a Caterham electronic speedo and the 8 pin connector for the speedo.
However there are two wiring diagrams, one from Caterham, and also one from Caerbont (who make the speedo), but the diagrams are different. The speedo doesn't work in either configuration. Caerbont have helpfully suggested swapping the wires around, but with eight of them there are a lot of possible combinations.
Does anyone have any experience of fitting an electrical in place of mechanical speedo?
