di2 front harness, 1 red flash

[redfalcon]

bike does not shift, when I hold down the front harness button 1 get one red flash.
Anyone knows what this means? can I fix it?

Means your battery is dead. Charge that bad boy!!!!!

[redfalcon]

well, I swapped batteries with a known good one, and same problem

Well that's not what I wante to hear. The only time that has happened to me was when my battery died. Maybe take it to the shop and have them use the diagnostic tool? If you know someone else with Di2 try swapping components to see if you can trace the problem?

Try to hold down the button until the red light flashes a few times. Then release, wait few seconds and try shifting again.

What kind of setup you have with Di2? Is it all original?
