1.25 amp battery charger problems

I have the charger hooked up to the pigtail on my 2016 street glide. I plug the bike in then plug the charger into the wall. I get a steady amber for a couple hours. after that I get a steady amber and a blinking green simultaneously. I checked the P&A fuse and it looked good so I swapped it with the radio fuse to be sure. the radio still works could someone please help me figure out what's going on???

Is it working for input 240V?

I bought this one from San Jose - US dealer with the part number is 66000033. It shows this tender is universal fit, and the package also mentions that it is can use 100 - 240V. However, the label stick in the tender mentions "Part No. 022-0185-HD-WH Input: 120V ~0.35A 50/60Hz Output: 12V..., 1.25A" as the picture attached. The serial of the tender is (S/N): 2815-100602C I am not sure if this is wrong sticker or my misunderstanding. Please let me know if I can use 220V for this tender? Thank you.
