1966 Mustang Temperature Gauge and CVR Testing

I test the CVR (constant voltage regulator) and temperature gauge on a 1966 Mustang.

All of my gauges work, but all of them, except the voltage one read sometimes correct and sometimes high. Mostly high. Would it be the CVR or something else, like a resistor?

I'm sure it's the same with a 68, right?

Nice, but it would be better if the cam would not move so much... Thank you anyway.

Too much Camera action.
