Hi All, I've added the DigiTrax DN163K1C to my new Kato SD79ACe. The OEM light board took a bit of effort to remove but the DigiTrax board went in nicely. After programming, the Loco sped around the layout nicely, however, the headlights do not engage when turned on. Usually I have the opposite problem and it's motor tab related. Where should I check for a solution? I've done a factory reset and nada.
