Thanks guys,

Ferdman, Yes I have a very small metal sleeve around the boot so it sounds like I got beru.
Do I have seperate resistor ends also?

If so, I got a wire arcing at the boot to the cylinder head, is it the wire or the resistor end that needs replacing or both?

How do you tell which is bad? I'll replace whats needed but if something is good,theres no sense.

Thanks, Jeff
