rpm gauge not working

changed my vavle gasket , spark plugs and wires , started the car no response from the rpm gauge. i thought it was the wires so i changed them back but stiill nothing.

Male sure your distributor is fully plugged in.

distributer fully plugged in still no response

Did you test the gauge itself?

no i didnt and i wouldnt even know where to start. can you give step by step instructions on how to do that please.

Do the other gauges work?

yes the mph gauge works and also the temp gauge. but the temp gauge moves up and down sometimes,
