Ok, I seem to have some sort of speedo problem at the moment. It's difficult to demonstrate exactly what is wrong, because it's so strange. Anyway, most of the time it's definately wrong! It seems that a lot of the time it reads in KPH, sometimes it flicks back to MPH, and sometimes, we suspect it reads somewhere in between.
Also, the rev counter may be off too. Not sure. It's only a suspicion that the rev counter is wrong - I have certainly see it move when the engine revs are not changing! (For example, when cruising down the motorway I can see the revs change even though I am at constant speed). I'm not sure whether the revs read right when the speedo reads wrong, or whether the revs read wrong only when the speedo reads wrong, or whether they're completely independant of each other!
The idle seems to show 1500 even though it seems to be nice and slow and regular like the approx 750 it should be.
I am wondering whether it's actually read 8/5 times that of what the revs should be - just like an inverse conversion of MPH to KPH. I am pretty confident that it has a speedo converter wired into the electronics behind the dash, as i have seen something wired into the loom that I wouldn't expect to see there. I have also seen some suspect wiring in the loom in another place, which I have corrected, so I was wondering whether the speedo converter could just be wired in with rubbish soldering.
Sorry about the long post - but if anyone can offer advice or help, it would be most aprreciated! It's doing my nut in! :)
