hey guys, having problems, i have 1991 none turbo jap verson of car running in kph, trying to convert to mph, am on 3rd mph unit now, and all dials work apart from the spedo dial its self, any one know if im missing anything or something should be doing, the kph unit works fine, thanks

Are you changing the dials, speedo itself or are you using a converter 'chip'?

 

I've just bought a converter but haven't fitted it yet. My speedo goes to sleep regularly and it's something I'll address when I take the binnacle out. Apparently they're infamous for dry joints on the back of the PCB so it's out with the soldering iron.

 

Maybe that's what's wrong with yours.

am changing the dials completly, its 3rd unit now trying and just dont work in mph, my kph one works fine, just dont understand the mph dials not working, didnt know if something else need to do if putting a uk mph unit into jap kph car

So far as I know it's a straight swap. Are you swapping the speedo itself or the complete binnacle? There is a difference I think between S1 and S2 binnacles, but I can't say if the speedo units themselves are the same between them.

 

I bought a set of UK clocks and they were screwed. Would hate to think you've had three sets.

 

Check the PCB for dry joints though, I would say it's a good start.

change the complete binnacle, yea nightmare on the 3rd, do you think would work if just swap the mph speedo itself into the kph unit, will also check the pcb see if is dry joints

Might be the speed sensor on the gearbox that's not working.

would the speed sensor work with kph and not with mph if swaping them or is there something need to do with that sensor
