Turn Signals Scrambler 900. 2023

Hello People, new to the group. Just bought a scrambler 900 2023. Super cool bike.. i have done a fee mods to the bike already and i appear to have a problem with turn signal. All the install was done correctly. The turn signals work when ignition on but as soon as engine is turn on the signal just lights they wont flash. Any help would be very appreciated. I have plugged in a code reader and no code was active or stored
