I've posted about this before and have searched extensively with little to show for it. The odometer on my Rx7 is no longer working which seems to be a fairly common problem in the community. I have come to the conclussion that the only way to go is replacing the guage cluster with another hopefully around the same mileage. Any other ways to go? Does anyone have an cluster that has around 70,000 miles on it? If so please let me know thanks

 

Although I have not done it myself, a friend of mine fixed his by just replacing one of the burt lamps...

 

what exactly problem it have it work but didnt have light?
Or it didnt work at all?
The needle work?
It can be a broken soldering ball before pay for new one take it out and go to electronic technician to resolder all the pcb also it have some power transinstor and regulator you can check if it is work because this one give power to odometer to work.
I hope the cpu still work otherwise you have to search for other odometer.
