Just wanted to give a heads-up to those 3rd gen owners with odometer displays that stopped working. After spending a few years in storage, my FD gauge cluster failed to display the mileage. The fix involves replacing several capacitors in the cluster. While I am handy, this was not something I wanted to attempt and risk further damage.

I was not sure if many FD guys have used them previously, but I gave DNA Speedometers a try. They are based out of Tampa, FL. The repair is a flat fee (PM for details), and the turn around time is 2-4 weeks, depending on their backlog. I sent them the entire cluster.

My cluster recently came back, and is now showing the mileage. Way better than having to replace the unit.

 

Yes, DNA is the place to go, for sure. Many, many other threads on this though...

 

It is pretty easy to replace the cap, I had an intermittent odometer so I took it apart to replaced one of the cap above the speedo, and I did it without separating the speedo from the circuit board.

No more blank odometer

 

sorry to bring this thread back. what happen to me is after replacing the said capacitors the odometer worked for 2 weeks. after 2 weeks. the odometer is still working every time I put the key in the on position. But once I start the car odo numbers disappears. don't have any clue what's going on now. lol!

 

I had the same situation and had replaced just the one capacitor and it quickly burned out again. I have a few theories but the next step is to replace all of the caps as other failed caps can quickly burn out the newly replaced cap.

I bought another cluster but it has its own problems so I will be back at this again soon.
This time its the tach not the ODO that doesn't work but I believe its the same issue with the caps.

 

Let me know wazzup. I'll be gone for a week. When I get back I'll try to test my cluster for voltage and grounding. Hope that works. And iv read some old post that it worked for them by starting the car using crank the car first then step on the clutch.pretty much it's key first without the clutch then step on the clutch. I'm gonna try to change the capacitors again if those steps doesn't work.

 

Thanks for the tip!

You're not alone in your frustration. The ODO repair has been the single most pain in the *** repair I have done on this car. I finally have mine working most of the time (it has to warm up before it comes on most days) after having it in/out 4 times on my bench and once to Southern Electronics in Richmond, VA.

If you haven't already... Check out this thread for more details: https://www.rx7club.com/3rd-generati...ometer-599220/

 

Done that. ODO works till you start the car. Once u start the car.numbers goes out.

 

Another Great thing about DNA speedos in Tampa -- if they can't fix it -- No CHarge!
I sent them one that was just too Dead, they checked it out and sent it back no charge.
Definitely will use them again. Probably soon since the replacement speedo I picked up
comes and goes already.

 

i dont know if DNA still doing FD odometers. i tried to get a quote they didnt got back with me and they saying that they have no luck on FD odometers.

 

Search on my username, best way to fix it is to get a low mileage JDM cluster, swap your mileage chip over, and calibrate for MPH.

This is especially true with '93 speedos, they're just crap.

Got the ODO running again. Tried to tap ground and 12v bit those ddn't work.i replaced the caps again.lol.

 

Mine also stopped working.
Question: does it still count the km's while its not working?

 

If it's totally out it doesnt. Just change all the caps again and it's should be fine.if it goes out again re solder again.lol

 

sorry to bring this back as it was years ago but could you tell me from your pic with a circle which capacitor it was the one you changed as I just got a cluster that has been stored for years and the screen didn’t show the km on it
it all looks new and all works just not the screen I don’t mind changing the hole thing from one cluster to the other but one is 180km and the one with the not working screen is 300km one
And I’ll also like my original milage tbh

thanx

hi
thanx bud
ill take a look a it and see if I can sort it out as it’s doing my headin lol

thanx
