Default Need help please to identify the problem!!

I have classic instruments gauges that were installed by the previous owner ( since 2011).

The tachometer and the speedometer used to work before taking everything apart to restore the car.

A digital tach was wired and it works fine but the analog gauge in the cluster does not work.

Regarding the speedometer, I realized that the speed signal generator ( classic instruments part no SN16) was not responding when hooking up a voltmeter while rotating the speedo shaft. So I installed a new speedo sensor for my Tremec TKO 500.

The car is suspended on 4 jack stands, so I turned on the engine, hooked the voltmeter to speed signal wire and ground at the classic instruments connector, put into 1st gear for slow rolling.

The volts started to alternate between battery volts and zero but the speedometer pointer in the cluster was not responding at all.

If the speedo pointer in the cluster was not responding, does this mean the gauge is bad and it is time to new gauge cluster

Will appreciate your input guys
