It worked
Sure took a lot of figuring to understand something so terribly simple, but now
I know how!!
The switching relay works oh so well.
Plug in the power cord, and it disconnects the battery, and supplies power from the converter.
All faster than a fellow can blink!
Now I'll never have to worry about too much voltage from the charger.
Thank you all for your time, effort, and concern!

Waiting for "someday" will leave you on your deathbed wondering why you didn't just rearrange your priorities and enjoy the time you had, instead of waiting for a "better" time to come along...
