Rev Counter problems

Hi my rev counter has never worked on my TR 7 v8 and have taken it out to see if the 48k ohm resistor had been fitted to make it compatible with the V8. It does have an additional resistor but this does not appear to be fitted in the same place as recommend on the conversion guides and here is a pic

I'm no expert on those tachos but I would expect "the 48k ohm resistor" for V8 to be a scaling adjustment. Without it I'd expect the tacho still to work but show double the actual revs.

The grey resistor in the foreground is a 47K. If somebody has modified it wrongly then that might explain it not working. Do you know the history of this tacho?
