Went to start my 2003 ford ranger regular cab truck and battery was dead. Jumped it off and now lights flicker and speedometer indicates 10 miles per hour sitting in the driveway. The speedometer needle is shaking. Any idea what the problem could be?
Actually the Speedo is controlled by the PCM I would pull the NEGATIVE battery cable for 30 minutes and then hook it back up. this will reset the PCM.

Yes you have burned out the circuit to the speedo motor, did you jump it incorrectly???
