8N spark plug boot.

I have replaced my spark plug wires with wires from ST tractor. I was testing for spark strength today, good strong spark, and was feeling little shocks through the spark plug boots on all 4 cylinders. I turned off the lights in the shop while the tractor was running and I do NOT see any sparks or tracking but when I touch the boot with my finger I can feel the shock. Dad would say: Stop touching it! The shock is a lot less then an electric fence, but it does wake me up. I noticed the boots are made of a spongy soft rubber not the solid heavy rubber I am familiar with. Currently the machine is running good, and if I keep my fingers away from the boot I have no other problems, but I can't help but think these boots will eventually fail. Anyone have a source for good quality spark plug wires that not only have quality conductors but quality boots?

Thanks for any advice. Joe

STOP touching the boots when the tractor is running and put it to work.

Reminds me of the story about the mental patient who at every chance banged his head against the wall until he was bloody. Therapist asked him why he did it and he answered because it felt so good when he stopped :shock:

I would guess that a good hardware store or a Menards would have plug boots for mowers.

Soft and spongy doesn't sound good from an insulation standpoint. Also, are you sure these are completely dry?

Start it up at night and shut the lights off. I had to do that once with an intermittent miss that was driving me nuts. Turned out to be a small worn spot on a wire that was close to the fan belt that would arc once in a while.
 
Joe, NAPA, and possibly others used to carry good rubber boots. I haven't had the need to buy any lately. I would listen to what your Dad would have told you.
 

I will freely admit that I have fixed many things until I have broke them. Reminds me of the joke about the scorpian and frog trying to cross the river.....Its in my character! But I never walk away until I fix the opportunity I created. Thanks everyone. I enjoy the feed back of this forum. No better way to learn!

You got booties? Your wires are fine. That is indicated when you turn out the lights and observe there is no arcing on the plug wires. Plug wires matter. The good, copper core type is recommended. There are cheaper harnesses out there so it matters where you buy from. The OEM spark plug worse never had booties on the plug connection, only on the cap connections. Leave your hands alone ---
