I'm having an issue with a VL loco and tender (GS-5, SKU 2031570) where both drawbars, but especially the tender's, got damaged falling off a shelf. Other damage is only cosmetic, the engine functions exactly as it should but I think there is no signal between it and the tender as (1) the tender doesn't have sound, and (2) although the marker lights work, they don't change color and the reverse light does not come on.
I think that although I have bent the drawbars back into what I think is the right shape, possibly the signal connection between the loco and tender is misaligned or one of the IR bulbs has broken.
I have tried lining them up manually and looking for illumination in both of them but can't make out anything or get the tender sound to start. But I am actually not sure what to look for - I think that the IR beam is a kind of pink/blue when it is transmitting, which I have seen on other Lionel wireless tether engines.
Any ideas how to diagnose this problem? I hope it isn't worse than I think, as in a board issue. Have tried a soft reset but not inputting a new engine ID. Thanks in advance for any advice.
