Should the idle rotary valve click when battery voltage is applied to it?

I tested mine with straight battery voltage and I did not hear anything. Is that mean it's dead? I know the ones on BMWs clicks when voltage is applied. I am trying to diagnose a high idle problem that happened after a cylinderhead rebuild. Please search the forum for my last posting on this issue.
PS. I cleaned it with electric part cleaner and it was fairly clean. Still no click with voltage battery applied.
