I just finished installing a set of UK Clocks into my 1990 JDM TT Auto.

 

This seems to have rectified an issue that I had had with the auto box shift pattern...which now seems much smoother and to change up and down at the correct revs :cool3:.

 

All of the warning lights and gauges are working with the exception of the speedo. I'm assuming it must be a fault with the speedo unit as it was working previously with the JDM clock set...so unlikely to be anything outside of the instrument cluster.....is there anything I can check/test on the cluster itself?

 

Also....when driving...as you pull up to a stop...just before you stop there is a chime or ping :confused1:...any ideas?

 

And finally the instrument cluster light is dim...I'm guessing that could be the reostat on the right hand pod...but I don't recall it being dim with the JDM clocks...

It seems that the speedo signal is working but not the dial, common issues are dry joints on the speedo board itself, which means taking it all apart again im afraid to gain access.

You can disconnect the chime box, or wait till you have rectified the speedo, the chime bos is a little black box under the cowl at the top of the dash on the left, if you disconnect you wont have the lights left on bong, so no great loss.

 

The dash bulbs may need replacing, but make sure the dimmer is up ( drivers pod)

Thanks Groover.......why does it bing/chime as you pull up to a stop?....it didn't do that with the JDM clocks installed!

 

Also...is it an option to swap the speedo mechanism from the JDM clock set (utilising the UK dial fascia)....or does that negate the benefits of fitting the UK spec clocks?

The resistor on the UK speedo is what determines the correct speed, you would be going back to JDM if you swapped the speedo dials over.

The bong at a stop has happened before on some previous threads, might be worth doing a search, but i think its speedo related, ie corrupt signal from the speedo board, in some instances the needle has suddenly jumped or stutters.
