Hi everyone, I have a 1995 xjs in mint condition...it was my dads,so i keep it covered in garage. Battery had to be replaced so I did and everything started and ran beautifuly, but the speedometer is stuck (pinned) at full speed and wont give any other reading than that. Took it for a spin (35mph?) and still wont come down from full speed.....can anyone help please? THANX
