Picked up a Lionel 229 diesel switcher on ebay in "parts only" condition. I did manage to get it running quite well, and separately tested the horn, which runs on an on board "C" cell battery. When hooked up to the train, however, it doesn't work. It's powered by a KW transformer with the whistle button, but when I press it, I get nothing. I connect the points on the horn relay, and it works, but the relay won't work by itself. Not sure if the coil magnet is any good or not. Is there any way I can test this relay to make sure it's working? Also there was a lot of broken wires on this unit, and all I had to go by was a grainy wiring diagram I downloaded. I know there's some really sharp electronics guys out there, and I could certainly use your help.
