I can certainly tell that you are like me, a terrier. I don't give up until the solution is found, which at times is very frustrating.
I spent 1.5 years troubleshooting my first restoration 944, which had a "no-start" condition, so I know how you feel here. I also agree that there IS no limit to the amount of pages it takes to resolve an issue such as this.
( It's Wayne's website and I don't see, or hear him complaining about the amount of pages we are using here to resolve an issue!)
The bottom line is, it helps everyone in the future, period!
The solution is near, however, in view of all the data you have provided. This data, is what, we the Pelican community, will be most grateful for in the long run. It WILL save someone else a lot of time and money to resolve.
Don't give up and keeping posting your results!
