I down loaded UP SD9043MAC Numbers 8008, 8037,8087 when I run them AI the door at the front of the locos is open. This doesn't happen when them manually. just curious has some else come across it
Try activating the pantograph again and see if the door closes. There are four settings.
1. Pantagraph down - Door closed
2. Front pantograph up - door open
3. Rear pantograph up and front pantograph down - door closed
4. Both pantographs up - door open
