Okay. Hubby took the top off. The positive red wire leading to the center pin can not be adjusted. For some reason he can't explain why the attys are not making a connection. So, I'll look for a dud on sale, a spare part top or just give/sell it to someone. They're still at a good price. It's fully charged, OLED is fine, blue color, and in really good condition. Love that it's 3800 mAh with that USB on the bottom.
If anyone knows or has that spare part, please let me know. Thanks.
