Leonard - you're being very non-condemning in your reply, aren't you?
My opinion, without naming names or slinging arrows at anyone, is that some people really should not try to do some of these modifications! You DO have to understand a few things about electrical circuits, don't you?
I've never investigated these things at all, so I was only reporting on problems I had read about in the other forum. You've pretty much confirmed something I've suspected for a long time - if you can follow directions and use common sense, you'll be OK.
When I have some time and more money, I may investigate them more fully!
Thanks for the clear, straightforward post!
