Default 1991 RPM Gauge Question

My 91, L98, six speed has a RPM gauge problem. When I turn the key to ON the RPM needle slowly moves upward, when I engage the starter the needle pegs at 6000, when the engine starts the needle drops to zero and does not move anymore. I bought a used cluster which the owner says worked fine but when I installed that I had similar problem. Help.

Just re-read your post, guess a tach problem would be something else.

It is the tach that isn't working. All my other gauges and the speedometer work fine.
