Super H plug wires

I reconditioned my 53 SH about a year ago and put new plug
wires on at that time. I was wiping down the motor with it
running and it shocked me hard. Jumped about 3'. Not being
any smarter than I am I tried it again and determined the plug
wires are arcing through. I thoroughly inspected each wire, with
the motor off this time:), and no obvious cracks. Tractor runs
really good.

What's up with that? Cheap wires?

These wires came from NAPA. Any suggestions on a brand and
type that won't do that?
 
Plug wires should be either Magnetic suppression wires with a real metal wire wound around a synthetic core, or real copper wires. Make it work.

Doubt there's a problem with the wires. Rather moisture from your wiping activity (or dew) coating the wires created a temporary conductive path from a spark plug terminal, then through you then on to ground.

You might try this: Run the tractor in absolute pitch darkness and observe the plug wires (give your eyes a few minutes to acclimate). If you see any blue or yellowish discharge (glow) on the plug wires the insulation has broken down. The wires should be replaced. Otherwise the wires are fine.

Tip: Shut down the engine when working around the ignition! I know mechanics who have suffered broken arms, elbows, etc from being "bit" by ignition and the involuntary reflex causing their arms to snap back and hit stuff.
