I got it turning manually. So I tried spinning it with a drill to get the odometer to move and it did for a few seconds at 70mph and then the needle dropped to zero mph. When I inspected closer pieces fell out of the light hole. So something catastrophic occurred inside. I couldn't even identify what the pieces were on my dirty garage floor. I have the car up on stands and have been cleaning and removing all sorts of stuff so there is dirt and debris everywhere.
So if anyone has a 140 mph Mk 1 unit, let me know.
