Attached picture nicked from ebay but my Indy has the same clocks. Sorry for the newbieness of this question but I'm a dullard with electrics and I have a dead speedo. Does anyone know what make these are and how they would be wired in on a blade engined car? I need to start the search for the fault. TVM.

Have you got a pic of the backs?

the look like ETB instruments, have a look at the bottom of the speedo in curved lettering

If they are then the speedo probably has 2 small cables that pick up pulses coming from magnets usually secured to either the propshaft or the diff flange.

Greenguages or ETB I would guess

There ETB

ETB with magnetic blocks on the propshaft.

The pickup will have failed.....been there dun that!
U2U macspeedy for more details

Thanks all. Just downloaded the manuals from ETB so I can work out what I need to replace.
