I have a pair that I bought off of Ebay and the flashers don't flash, one red led lights up on each cross buck and does not flash however the gates do operate correctly. Are the led bulbs burnt out? Is the PCB board defective on each unit? I have the wires hooked up correctly to the 153C contactor per wiring instructions and to the correct voltage. Each crossing signal does work independently or together the same as mentioned above. I did get a refund from the seller and was allowed to keep them so I am trying to repair verses discarding them. Any help is appreciated. Ed

The gates are not in warranty so I am attempting a repair on my own. It's a challenge as well because I am a retired Lionel Service Station called Ed's Trains and pre and post war is my specialty. I say IS because I'm still repairing but Lionel retired me because I didn't want to get into all the new electronics with circuit boards. This item has a circuit board and therefore creates the challenge that I've taken on. So I'm looking for any help that I can get,however I understand most would trash them if not under warranty. Ed

I didn't mention on the original post that the LEDs that don't stay lit do very briefly blink so I think the LEDs are good and the circuit board is faulty. What's up with NLT, I entered all the correct data into their parts search and came up with item not found so I emailed them a week ago with no response. Ed
