Take main battery leads off and carefully check them (both ends) , pay special attention to the earth leads.

Remember you need a good earth to both the body and the engine (gearbox it is bolted to normally)

Thanks for the info I have tried the earths and relays before but will give it another go. Would an earth fault effect the speedo and rev counter? because when this happens they drop to zero or go full deflection

[spider]

Yes earthing faults can have some very very strange effects

Look around fusebox for any earths there too (unlikely to have broken) under dash drivers side.

tried earths again with no joy. looks like unit called body service interface unit which is hidden behind the fuse board in the drivers foot well
this controles everything and gives symptons as I discribed,
a company called bba reman do repairs so I will give that a go

thanks for your advice I will let you know if it works
