Many times when the BATTERY is disconnected OR jumped the protection fuse for the ABS computer will BLOW! That will keep the speedo from working & the ABS/ASR lights will stay ON.
This fuse is in a computer under the hood on the passenger side. The cover for this box must be removed & then check these fuses.
The box looks like it has a "OIL" cap but IT isn't!! Good luck.
