Error communication with the battery
Hi guys, I would appreciate any advice. I have replaced faulty shutter unit on Canon 70D. Shatter is working now and camera works as it should however another problem developed probably during assembly. When camera switched on a message cannot communicate with the battery pops up. If option continue is accepted camera works fine only the battery info not available, shows empty battery symbol and battery info not available trough the menu.
I have checked few time and all the connections sims to be in place. Does anyone know what part of the camera responsible for reading battery information to narrow down the problem.
