Did you check the relay coil with a meter? It sounds like the coil is open circuit. Inspect it carefully and see of the ends of the coil wire are going somewhere and are not broken.
I will check with meter when I get one, but the insulated wire that enters the coil in the middle seems secure and the uninsulated wire that exits atop the coil and attaches to frame of rely is secure. I am assuming those are the two wires to the coil I need to be concerned with?
OK…got the meter, checked continuity from the pickup roller at the wheels to the armiture relay and there is continuity. I am not sure at what points to connect the leads to the relay to check for continuity? If anyone can shed some light…that would be great.
I confirmed continuity all the way into the relay. Not sure where to check at the other end of the relay. Thus far, everything I touch to is not showing continuity. I touched to the botton of the relay below the copper washers (lugs), tried the uninulated wire coming out of the relay. Not sure what else to try?
That wire coming out of the relay, although it looks uninsulated, in fact is.
You want to find the two wires coming out of the relay coil, and check for continuity of the coil by checking where they are soldered to their connection lugs.
If you have continuity here, then connect your dry cell battery to these same two points and check for relay operation.
Rob,
Are they soldered to opposite sides? One has the black insulation and is next to the other insulated wire above the point of contact while the other is on the opposite side and connects to the frame of the relay?
I see you are in Hopewell…I am in Poughkeepsie.
Opposite sides - see diagram below - 1 lug on right, 1 on bottom left.
Yes, only 287 miles away, and on the main line of the Finger Lakes Railway(Former NYCRR Auburn Road)!
Those are the ones I thought…no reaction whatsoever on the multimeter when I touch the pins to those two lugs.
We have a Hopewell Junction about 8 miles away. Beautiful country up where you are…as a child we once vacationed on Lake Conesus and my Nephew was married in Aurora and had the reception at the Aurora Inn on Cayuga.
Thank you all for your input. I went ahead and purchased the relay on ebay, got it, tested it, installed it, and the whistle works like a champ! I would have been lost without the great feedback I received…I really appreciate it!
