I had a battery problem several days ago---positive terminal would move--- and lost total power. Installed a new battery and everything is OK except the total mileage does not show---just a line displayed. The trip --1 and 2 display and all other functions show. This is not the first time the battery has been out of the circuit--by the way. And each other time when re-connecting the battery, total mileage showed up. Any ideas or suggestions. The bike is a 2016 Icon.
