Recently accquired Caterham 05, Tach registers double the actual value...Tach experts (Noisonger) advised, if working, may be ok, check installation. Unit (electronic ignition)appears only inside distributor, no points, just a small black box sitting where the points used to be.....which manufacture or type is the best for this set up? There are no external electrical units installed with this ignition.
I have checked rear of tach and ran thru all the available setting options, no difference.
The manufacturer identification is not readily apparent....an option would be to replace it with a new and improved electronic ignition, any suggestions?
