odometer not working

[fast_cat]

The odometer and trip meter stopped incrementing on my analogue speedo recently, although the speedo still works fine.

I tried a few resets of the trip meter but no joy. So removed the speedo from the car and checked it out further and a bit of WD40 just to make sure all free. All looked ok and cogs would still rotate manually.

So then I used a squared off nail and electric drill and this worked fine - speedo, trip meter and odometer all working and incrementing fine.

So I put it back in the car and......

speedo works, odometer and trip meter still not incrementing.

So is the cable broken ? - maybe the squared off end is not working, but if so how is the speedo still recording the speed ?

thanks in advance

I'd guess the mechanical drive to the meters inside the speedometer is on the way out. Perhaps the cable is putting a bit of side force on the drive or the angle at which you tested it is a bit different from how it sits in the car.

Fortunately there are some trusted repairers.
