Help with a miss and voltage drop

Ok so an update of sorts. I removed the plugs again, and reset the gap down to 40. And now the miss is hard to find. And it doesnt drop the voltage down. At the same time I also replace the wire that was coming off Alt going to the ICM, as that wire was looking strange, like the wire inside was fading?? I will keep testing it out and see if that Miss comes back. thanks for all the help. I see on Youtube, people take a water bottle and spray under the hood at night, and you can see small arcs. Has anyone tried that on the Slant??
I've used the water bottle misting on just about everything, Std. points, HEI, DIS, COP, You name it,.....if there's a high tension leak it will easily help it rear it's ugly head.
No electrocutions in 33+ years of it, just don't test it with Your tongue like a 9V, or feel compelled to grab it where it's sparkified & sizzlin'!!!!:rolleyes:
