when driving at highway speed of about 70 mph the speedometer, tachometer and volt meter pegs out and vehicle runs normal. any idea what could cause this condition
Could be a bad ground for the cluster, but I think it may be in the charging system controls, if I remember correctly they are controlled by the ECM on this truck.
