Instrument voltage regulator

Well Red maybe you COULD post the right way to do it. Frankly I've of the opinion that there IS several ways to approach this problem. At least one involves some sort of material, goop, silicone, epoxy, whatever, to safely isolate the offending parts.

I've said this before. You have to use your head. You have to think it through.

You seem to be of the opinion, that it's your way or no way, AND I won't even tell you how.

Well, alrighty then, and thanks for your help

How ? Grab the limiter with needle nose pliers and peel it out of there. That's the easy part.
Opening the gauge and closing the gauge is where many have screwed up. I cant detail the opening and closing because they aren't all assembled the same. Some are crimped, Others have brass brads.
What disturbs me so, The "do it yourselfers" do successfully open then successfully close without having done what needed to be done. Not their fault they were misinformed. Not mine either.
