Neal, please don't take offense at what I'm going to say because I'm trying to help.
I see you've worked on your Oasis system in the past. Whenever I have a problem, I always retrace what I did and there have been more instances than I care to admit that I caused a follow on problem.
When was the last time your Oasis system operated trouble free? What did you do to fix that? When did problems crop up after that first repair? Are your problems different than those that existed that caused your first repair attempt?
Hope you get this figured out to your satisfaction soon.
