please help..son crying now

see other post…thank you!!!

Well you have two wires coming from the transformer. These should connect to something called a lock-on. One wire is attached to each of the connectores on the lock-on. Sometimes its difficult to get the lock-on onto the track. It should sort of snap when it is attached properly. Thats it.

Keep trying and keep us informed. No question to dumb here. Good-luck
