Hey guys,
My MSD wires are about 5 months old, I was adjusting my timing and when I grabbed the top of the distributor to move it BAM I got zapped. So I checked the wires and the boots, no cracks, cuts, tears, nothing.
I made sur the boots fit in the cap...I was adjusting it and I got zapped again.
Could these wires be defected.
Thanks

A lot of voltage leaks from the plug wire boots. Dielectric grease helps some,so does that heat shrink tubing that covers the boot/wire. Check it out at night for a light show...

Try not touching the fender or any other metal, of course that completes the ground.

Are you using the MSD box as well?

I know how that can bite!

Electricity is lazy. It takes the path of least resistance. If the resistance between the car, your arm and the boot is less than the resistance of the plug wire, the plug resistor and the plug gap it's gonna go through you. Work up a good sweat and it only gets worse.

This story reminds me of the time I used to work for a rental car agency. One of the customers returned a car because the car would not turn off when the ignition switch was turned off. You could remove the key and the car, a F*&D Lincoln Town Car no less, would just sit there and idle away. This went on for 30 minutes while the master mechanic tried to figure out how to shut it off. He disconnected the battery thinking that would work-NOT! Finally he gave up and said he was going to call the dealership to see what they recommeneded. My quick thinking was to grab a towel and rip the coil wire off thereby stalling the car. Let me tell you, even with that darn towel that was about the most electricity I have ever had pass through my body! Needless to say the car stalled. And to think, all I really had to do was remove the fuses one by one until it stalled. What can I say, I was 16 at the time and not nearly as smart as I am now..

Yeah, I got zapped so bad from an MSD6AL, it took about 1/2 hour to get over it.

Pain...

I took the wires back to the Hot Rod shop and good thing, they exchanged them.
I'll put them in tonight and see if I get whacked again....
One other thing, the 6AL box goes for about $195 here, Guys know where I can find one for a good price?

Rubber gloves are wonderful things!!

I always grab the sides of the dist or the vacuum casister. Grabbing the top is asking for it even with good wires and boots.

Me too!!

About 25 years ago I owned a Datsun 260Z. (Fun little rust bucket) I had just finished replacing all the ignition wires. It was a nice hot day, no shirt or shoes and plenty of sweat. I fired the car up and with it idling I decided to check that all the wires were pushed on tight. NO ROCKET SCIENTIST HERE!! I grabbed hold of the coil wire to give it a check--ZZZAAAPPP!!! I have never been hit harder. I could feel the current move up my arm across my chest and down my body to my legs and feet. I don't remember how I got loose. All I know is that I felt really-really bad for the next three days. I think if that would happen to me now at the age of 48 instead of age 24 it would probably kill me.

STUPIDITY AND ELECTRICITY DO NOT MIX!!

A dead stock HEI coil, is worth 50,000 volts. No matter what kind of module or box attatched to the coil, it is still only the coil, that fires the voltage to the plugs.
A good ignition system will only need 10,000 volts, with a nicely tuned engine!

True, it's still only the coil secondary voltage, but it hits multiple times.
