Speedo Problem on 'Carmen' 4.0L XJS
Hi Guys
Got a bit of a problem with the Speedo on 'Carmen' my 4.0L Six Cyl XJS that I've never come across before
When I went to Start her up, the needle on the Speedo suddenly went right over to 150 MPH even though the Car was stationary and then the needle stayed there and wouldn't return to Zero when the Car was switched off
Even with the Battery disconnected
Any ideas?

I’ve had this happen & to get the speedo needle back to zero I had to remove the instrument cluster & whilst holding it, rotate it through 180 degrees anti clockwise to get the needle vertical & then rotate it another 90 degrees anti clockwise to get the needle back to zero. Mine was related to having the battery discharge over a period of time & then reconnecting a charged battery & turning on the ignition - AKA just one of those things!

Same thing seems to have happened with mine!
Battery went flat, put on a New Battery, Speedo went right over to 150 mph and Stayed there!
When you say rotate the Instrument Cluster, did you mean the whole 'Binnacle' or take the Speedo out of the Cluster first?
It sound like you meant the whole Cluster but just want to double check
