Trying to eliminate the HT leads from our hot misfire problem.
http://www.peachparts.com/shopforum/showthread.php?t=158510
I want to test their resistance, both when cold and hot, as suggested in other threads, but am unsure how to do it correctly.
The leads are pretty new according to the PO bills we have.
We have looked in the dark, and no leakage showing.

How do I do that and what am readings am I looking for?
Any ideas on replicating the hot underhood condition?

Sparks at night are a GOOD sign of breakdown.. spraying water will really show a leakage problem.

Thanks MB,
I will spray it tonight, and see if there are any fireworks!
If there is not, any ideas what to check next?
