Speedo Still Don't Work

Hi there all,

 

Right then, I've put a UK cluster into my JDM and the speedo and odometer aren't working. The cluster came from my old UK car and were working fine, its only since connecting up into the Jap car it don't.

 

I've tried the following and now have no idea where to go with it now.

 

1. Dry solder on the PCB. - There seemed a bit of crap solder there so I re-soldered it.

2. All the screws are in the back

3. Re-glued the EL dials and the needles aren't catching.

 

There seems to be a weird green/yellow wire doing its own thing, pics below.

 

Any help please guys, cheers.

Not sure how much this will help but

 

When I delimited my NA my speedo and power steering started to cut out. Problem was the 12 volt wire that the chip was connected to was not up to the job of powering the speedo, power steering and and delimiter so we just moved it to a different 12 volt wire and all has been fine since.

have you removed the speed resistor from when it used jap clocks? it may well be a fault in the printed circuit board on the back? im guessing there. however, you can easily disasemble the clocks and pop them in so it may well be work popping the uk speedo out of the cluster putting it in the jap spec cluster. im not sure if that can work, but its worth having a look into. im sure somebody said to me if your rough with the cluster it ****s them up.

Hello mate,

 

Regarding the speed resistor the answer is no as I don't know what one is, it doesnt have a speed converter as there was no extra wires connected to the Jap clocks. The Uk clocks have been removed a few times so there may be some damage I don't know of, nothing obvious tho.

 

All the other gauges etc work fine

Mine doesn't work either, i thought it was the cluster so i changed it for another jap spec one (but converted to mph) but still only works when it wants to. Been told it could be the speed sensor on the gear box that needs replacing.

mine only ever works when it feels like it too, mostly when the weather is nice. when it rains, it stops again. so i'm guessing its probably the speed sensor too.

Mine used to work fine, up until 60mph, then drop to zero, so I changed the kph/mph converter for one I had lying about, it now works fine up until 80mph, then drops to nothing, which is strange, the fact the fault is different, so I'm going to do the live feed fettled as mentioned above, sounds logical... Also, if I accelerate hard, with either converter it would drop to zero before it would get to 60/80, so again, sounds like the live feed from the screw at the back of the speedo isn't quite juicy enough, if that doesn't cure it, I shall have a look at the speed sensor...
