Safety while working with spark plug wires

[Steve Baldwin]

Pulling plug wires off with the engine running is something that I do
reasonably often to find weak or missing cylinders. This is mostly on
older points type igntion where the leads are often dirty too.
Side note: Dirty leads cause no end of bother when there's a bit of dew
about. Far easier for a spark to go down the outside of an oil/water
covered lead than through the carbon center. Discovering this also
causes pain.

My method for yanking leads off is to pull them off with a jumper cable.
Clip the other end to a good earth and hang on to the insulated handle,
clip it onto the boot and pull it off.

I like the idea of the plug with a hose clip though.

Steve.
