Normal range for temp gauge
I'm getting reacquainted with owning an old American car again and wondering what's your normal range for the temp gauge? It's a 1991 E350 club wagon with the 460. The entire cooling system is brand new except the heater core. Copper radiator and 180 thermostat. The original cooling system did not have a coolant reservoir. The replacement radiator had the nipple below the radiator cap, so we added a reservoir.
What bothers me is how active the gauge is. Cruising along, it stays right about half. Stopped at a light, it will creep up to the L. Right around the A or L is when I can hear the fan clutch kick in. Well, I can always hear the fan but that's where it's really pulling. Soon as I get going and the gauge is below the A, the fan is quieter. All of this should tell me it's doing it's job just fine but all the cars I've ever owned, US and import alike, the gauge stays more in the lower half at all times unless there's something about to make it overheat. Do I need to just let this go? I watch my gauges often and I get anxious thinking it's on the verge of overheating all the time.

Now that I changed my search results to relevancy, I found my answer. Gary's extensive talk about the instrument cluster voltage regulator was way more than I could handle but enough for me to leave it be for now.
Just figured I'd put this out there before the resident "use the search" person chimes in.
