I have a thread going on the Flyer "S" Gauge thread. Trying to fix a Flyer 490 whistling baggage car. It uses a DC relay, ala Lionel, to cycle a 'reverse' unit to turn the whistle on and off. The DC relay is giving me problems.
I thought I had it fixed but no dice. The relay responds to AC. This in turn makes it 'chatter' and engages the reverse solenoid turning the drum, and thus, the whistle on and off constantly.
I took the relay apart, polished everything, but no change. It gets magnitised with AC and only slightly more so with a DC push. I have several 'parts' Lionel relays and they only close their contacts with DC. A Lionel relay won't fit in the baggage car (as a possible fix).
What goes bad in a DC relay? How are they constructed as opposed to a AC relay used in many Lionel Postwar accessories? It's all staked together.
Any 'Chicago' Flyer collectors have a spare Prewar Flyer relay laying around?
