instrument panel lamps

The lamps in my 82 C10's instrument panel, wiper/washer panel, and heater control panel are fed 0 to 10 volts as I turn the dimmer knob. Would someone here please check their 5 amp instrument lamp fuse to see if they get full battery voltage with the parking lights on and dimmer knob turned full CCW? The fuse is on the lower left of a C10 fuse panel.

I'm guessing that the dimmer rheostat should provide full battery voltage in the CCW position, so that would mean mine is dirty or just plain worn out.
