Has anyone ever adjusted this little screw on the solid state IVR?

Great find!
Yeah, my '71 is still sporting it's original IVR as well. Not necessarily an apples to apples though, as it hasn't been actively used in years!
But like so many used car ads claim, "worked when parked" so it should be fine.
Hmm, I'll have to ask Doug what's in my '68.

Big thanks to @toddz69 for sharing where he got his NOS IVR. Lucky me, I was able to buy one today. Not-so-good luck for the rest of you, as the one I got was the last one they had. I have high hopes that this NOS unit will solve the various gauge issues I have now, since the wiring and gauges all test out fine, but the IVR shows inconsistently low voltage.

Todd, did you happen to check the voltage of the new design when you removed, as compared to when you set it?

And same for NOS IVR when you installed it?

I didn't. But I could check that pretty quickly one of these evenings...

I didn't check it either.

Feels like something shifted on the output on the electronic one if gauge was reading elevated. If so, thats not a great design.
