    Grounding/Instrument Panel Question

    97 GMC with instrument panel issues. I ran some beefy grounds thinking that was the issue.(after reading here on Big 3) No tach or speedo movement. Lights all seem to work fine. Battery reading goes to 19volts, temp goes to 210. Fuel has been weird as well. They don't move after driving it...
