Hello,
today I ventured to the garage to use two SP AA shark noses. I found that the rear was having trouble firing it’s coupler. So I tried to reprogram the set of shark noses only to find no sound or movement from the powered unit. (Note) I tried numerous ways programming them and found that the coupler finally fired, but it does not matter since the powered unit will not roll or make any sound what so ever. In p.s. conventional mode it ran fine. any advice helps👍🏻
