Tachometer and Voltmeter won't work! Any ideas?

My father and I are restoring a 1984 Camaro Z28 for my upcoming birthday. The other day, we started the car up, and now both the tachometer and voltmeter will not work: the tach starts @ 0 RPM before starting the car, then drops straight down, and the voltmeter starts @ 8 Volts, then drops straight down. What could possibly be the problem? Any help would be greatly appreciated. Thanks.
