No rev counter!!

Drove to Tesco, all good, got back in the car and rev counter isn't working! Fuses in footwell look fine, speedo works, turn signals work, all dash lights work but no rev counter! Nothing looks loose under the bonnet, all plugs are connected, fuses under bonnet look ok.. I'm stumped!
Any ideas from you intelligent lot?

Apparently the ICM in the dizzy could be a problem, but I thought that would cause a jumpy tach? Also could be something to do with a blue wire going to the tach, I don't know, plus its cold and getting dark so I'll have a look tomorrow..

(...not that anyone other than Newkid seemed to be able to offer any help here, so in the interest of completing threads...) ...I have solved my dead tacho problem by taking the dizzy apart and cleaning up the electrical connections, put it back together, fired it up, there was a delay of about half a second and then it jumped into life

TFFT!

dizzys are a pain in these cars - seem very sensitive imo - any trouble i normally replace the whole thing

glad u got it sorted and newkid pointed you in the right direction
thats a cheap fix and good info for future

I'm pretty sure my problem was to do with the connections in and around the dizzy. That said, my alternator belt does squeal a little, especially in the rain.. but I always forget about it until it squeals again and by that time its peeing down with rain and I don't wanna get wet! ..prob should replace all my belts really.

So the actual bolt broke?
