John,
I am baffled on the Lionel electrocouplers not working with the ERR unit. Again, there are only 2 wires coming from the trucks. One is definitely the roller pickup. I assumed the other would be for the coupler and somehow the other end of the coupler would be grounded through the truck (the only way I could explain one wire). Nothing I have tried will fire the coupler.
I installed a brand new set on the previous diesel I did and it went without a hitch. I was hoping to use the existing couplers on this one not only to avoid dropping another $40 on couplers, but coupler replacement on this one doesn't look to be exactly easy. Any ideas here?
Troy
