Please someone, recently our speedometer and tachometer has stoped working. Both needles are on the opposite side of the zero pin. The battery has not been touched (changed out, all normal) and all other instruments and gauges appear to be working fine. I have tried the reset procedure I have read on other forums but this didn't work. I tried disconnecting and reconnecting the battery and that didn't work either. I looked at the fuses under the hood and saw none to be blown. What is causing this and how can I fix it.
