I hope this makes sense

I fitted an mg zr speedo head in my old 200vi and everything worked as it should, ive just got one for my 25 but the speedo doesnt work.

The circuits differ between the 25 and the new zr head.

Both the new and old (200vi) zr circuits differ from each other too.

the old zr head worked in my 25 (before i buggered it) so i swapped the zr circuit boards over but still no luck

This surely indicates a problem within the unit? i have done a continuity check on both zr circuits and all is gooood

someone help, if i think too hard i'll forget to breathe!

yeah cause the 25 speedo head is fully operational and so is the buggered zr speedo head, just says im doing 30 when im doing 80. its just the new one which wont budge! its something internal to the new speedo head.

doubt it, theyre tiny and really fragile aren't they. hopefully he'll take them back, i dont want to pay for postage on them because they arrived faulty but i cant see it happening :S
