Hi All

I have a question if you can help.

I have Di2 with battery in the seat post, I wanted to check the battery but as I pulled the battery out the connections fell off so must have been poor soldering. Anyway my question is I don’t know which wire goes were, I have 3 wires 2 black and 1 yellow.
On the battery there are just 3 prongs with very small numbers at the bottom of each prong 1 to 3.

Any ideas

Thanks Miesta
