Erratic Rev Counter
Discussion
Been driving me crazy for a while this one.
The car seems to be running fine (maybe a little rich), but the rev counter will not settle down.
Seems to be over-reading erratically at low revs and more stable as you go over 3.5k.
Tried cleaning all connections at coil with no success - any ideas on where to go next??

I thought that may have been coming! To be fair I have recently (miles not months) renewed all ignition components and the alternator. I may just have to look into cleaning everything up a little and checking it's all tight.
As for the suppressor - I take it is a pretty standard item - any idea what it looks like - I may have binned the original when I threw the old dissy cap away??

I don't think they are Magnecor branded, but they were reasonably expensive - around £60. The only branding they have are '8mm Silicon Power' printed along the length, sounds a little suspect on reflection!! I also renewed the extenders at the same time.
Where would you suggest for a new set of leads?

If you can get a test meter on one of them, measure its resistance. A normal lead is over 10k ohms, whilst a low resistance lead is nearer around 2 k ohms,(these values depend on its lenght) so you can tell the difference this way. If they are low resistance, you can either fit resistive plugs, or an inline "suppressor" in the king lead as suggested, but its a messy option. Otherwise a set of origional lucas leads can be had for around £20 (Try some of the Land Rovers suppliers) that work just fine. The king lead will be the wrong length, so ask the supplier if they can do the correct one. I would not want to send you down this path unless you are sure the origionals are low resistance type however.

Ummm ....some where in between. Your best bet is to go and buy a cheap replacement king lead from a motor factor. Take the old one with you to match the connections, and a test meter to check the resistance is higher. I would suggest 10K is a better reading, and give it a try. If the problem disappears, you know the fix.
