Okay, I'm really confused now...

"...the distance between the two electrodes" - You don't mean the distance between the green lines in the pic below, do you? You're talking about the distance between the red lines - so the center of the arc of the ground and the electrode?




Most of my confusion is coming from the only wire gauge I've seen (and the two I have) are closed loops. There's no way to get the gauge into the curved portion of the ground lug since it has to make it past the points of the lug - which will be closer to the electrode than the arc.

Past that... since electricity will flow to the nearest ground, and the points of the lug are closer than the center, then won't the spark jump to the points and not the arc?

The gap between the CENTER electrode and the GROUNDING electrode, where the spark jumps is the GAP. That GAP needs to be ADJUSTED to .044".

Yes the points on the GROUNDING electrode will be CLOSER then the CENTER part of the GROUNDING electrode. That is to encourage the SPARK to jump from the sharper part of the electrode providing a hotter more focused spark.

Use a wire type gauge and inserted it BETWEEN the GROUNDING electrode and the CENTER electrode. ADJUST the GAP so that when you pass a .044" wire from one end of the GAP to the other you can do so with a little bit of DRAG on the gauge. YES the ENDS of the electrode will be TIGHTER then the CENTER area.

Is this making more sense now? I will try to SHOOT a picture of the PROCESS and post it in the next day or so.

Dude... relax.

I'm (we're all) trying to learn, but the information gets cloudy when you talk about "the two electrodes" and I read it as you're referring to a matched set of parts - which to me would be the grounding electrodes.

Also, when I first asked you about this, you replied:

Use a wire type gauge and you want to be able to slip the wire from one side of the gap to the other on each grounding electrode with some resistance, but not a lot.
Which, to me, read like "one side of the gap to the other" implied measuring across the points.


It also appears that I have to find a new gap tool since mine are closed loops. Until now, I'd never seen anything but flat feeler gauges and closed loops.

Trust me, I am RELAXED.

I don't get worked up until someone is trying to stab me or shooting at me.

Just tying to make things as CLEAR as possible and I am doing the best I can.

Most wire gauges I know of are LOOPs and that is what I use. I don't know why you are having so much trouble.

Like I said I will try to shoot a picture.

'k - good to know.

I'm not in front of the plugs and gauge now, so maybe I'm just having issues visualizing this. I'll work through it when I get home.


Thank you
