Beth – success! Problem fixed. Board not fried. The “wicked hard to push in” really helped – I, ah, “insisted” that the battery get seated oriented as in the picture, and now everything works. Thank you for helping me through this. -Dave
You’re right, apparently my RTC is fried since it will not hold the time/date. This is very frustrating, as I followed the RTC battery installation instructions on this forum at RTC battery installation instructions.
Can I get my RTC fixed, or do I need to throw away a brand new Mayfly? -Dave
Problem fixed! Problem cause: days ago, I tried to insert the Real-Time-Clock battery upside down. It made contact, but wouldn’t seat fully (of course). I removed the battery, but DIDN’T insert it at all. The Mayfly never worked again (I tried for days) until I gave up, posted my plea for help, and happened to install the RTC battery (the correct way). The Mayfly LEDs started to cheerfully blink. Dunno why this caused a problem, and I hope this helps someone else.
