Hu guys, recently bought the ultegra 6870 for a new project. This will be the first time I get into electronic shifting. Bought the whole groupset from Ribble and got them today. Installed everything according to the manual found on the shimano website. Followed everything step by step, but I have one problem.
The shifters doesn't seem to work. 3 port junction A lights up red when I hold it for 1 second but nothing happens. Holding it longer than that gets a blink red light with movement on both the front and rear derailleur. With the lights off, pressing the levers doesn't do anything. I disconnected the cables just in case they're loose and installed them again using the provided tool. Is this a firmware problem? I just assumed that it will be updated from the get go without me buying the £100+ box thing that connects the system to a PC for firmware updates.
So I have it like this, 2 levers, connected to Junction A, Junction A wired to Junction B by the Bottom bracket, battery, and both Derailleurs attached to Junction B. Doubt it's the battery as I charged it when I got it.
Thanks!
