How does this elderly Voltage Limiter work?
This is a Voltage limiter, for my Fuel, coolant temp, and oil pressure gauges in my '89 Dodge van. It plugs into my gauge cluster and is not extremely simple to access. My Factory service ...

My 7 dollar solid state solution is now in place, and my gauges no longer swing wildly for no discernable reason.
I mounted it so I can still fairly easily access the adjustment screw. It is at 5.12 volts now, and the gauges read a smidge lower than what was normal, on level ground with steady battery voltage, with no radio interference, or any other gauge swinging factors.
Red incandescent bulbs found their way into the cluster, and the green turn signal indicator and the blue high beam indicator got colored LEDS which are much brighter and richer in color than before. I went Incandescent on the background lighting as LEDS do not properly work with the stock dimmer, and I am not wiring up a PWM dimmer just to save ~1.25 amps that the 194s consume.
