I don't remember now why you didn't have access to this group's webpages.? I think something was preventing you from signing up the "normal" way, so you had to subscribe via email only.
I think you really ought to subscribe the "normal" way, so you can get access to the group's Files.? Over the last 14 years, there have been questions about contact bounce and about modeling arcing (sparks), and files uploaded about them.? I don't remember how completely those questions were answered.? But I think you might benefit from being able to see those files.
