There is a man in Yorkshire who knows all about these kind of things... He has a load of wiring diagrams and also does repairs and upgrades so you can use them with elecrtonic dizzys etc... I can't remember his name, but I did find him on google.
I've spend 10 mins searching google and not finding him. So I've been of no use but some else must know who I'm talking about.
I must have the details at home, I'll look tonight.

When I first fitted a Zetec into my Vixen, the rev counter needed to be converted from pulse to electronic. The guys knew what they were talking about and converted my existing rev counter shell, to hold electronic internals.
I believe ETB were doing/or had done clocks for TVR at some time (I maybe wrong, but thats what I recall being told).
The rev counter has never caused a problem sice.

Give them a shout, they gave a quality service,, theyre the ones to go with!

The guy in Yorkshire is probably "JDO Instrument Engineers" http://www.jdo10.pwp.blueyonder.co.uk/ (taken from a recent posting in the "S" forum).
Hi,
when I got my vixen on the road last year, my rev counter was doing a similar thing and was reading double (4000RPM) at about 2000RPM (not sure what had caused it or whether it had always been like it?). Anyway, it was the ford cortina type so was able to remove the back, drill a small hole in the case which lined-up with the small potentiometer on the circuit board, re-assembled and then calibrated it myself for 3500rpm against a digital RPM meter strapped on the coil.
Seems to still be accurate across the range.

Had forgotten that the rev counter was not working correctly.
Now the car is road legal this shortcoming appeared.
Checked wiring, earthing with no result.
Read things on PH about voltage stabilizer.
Connected one from a TR6 but no good reading.
Needle didn't go any further than 2200 rpm and stayed at that point even when engine shut down.
After some shaking the needle move to 0 rpm starting point.
Now opened the clock and found the problem.
A thin red cable hang lose and blocked the needle.
All sorted.
Sometimes you need all the time of an retiree.
