I have a boost and fuel pressure gauge and although they work, I just got back from a little spin tonite and they do not light up anymore(they have a red glow). It looks like all of the wires are still hooked up etc. and since they work I am assuming everything should be fine. H as anyone had this happen to them? Before I start tracing all of the wires is there a particular place I should look at first? Any help is greatly appreciated.
