Speedo Cable/Digital Dash Problems

[R.I.P.92Rolla]

My digital dash does work..the gas guage does work and lights also..but the speedo is not working at all..I have checked the cable and it is hooked up..What issues could i be looking at and the best way of getting it to work.

Call John at Caspers electronics. He can tell you what may be wrong. If the dash needs a rebuild he does that as well. He upgraded mine at the Buick Nationals in Bowling Green this year, it will now read up to 199 mph instead of flashing 85.
