I am trying to do a factory reset on two PS-3 equipped engines a 30-20108-1 IAIS GP9 and 20-20247-1 CUT GP9. I currently don't have the DCS installed on the layout for multiple reason and neither are responding and just sit there when power is supplied. I setup a test track and tried a factory reset but I'm not able to get the two toots to indicate a reset. I'm using a Lionel CW80 on the test track, so my question is: Do I need to use a MTH transformer to get these to reset?
Thanks for any suggestions.
