Any Communication to Fixing Prisoner of war Diesel Horns ?? (Lionel 2337)

Posted past MickeyDemian on Monday, December xx, 2010 12:42 PM

Merry Xmas Everyone:

  In attempting to fix the diesel fuel horn on my PW Lionwel 2337 for my grandson, I went out and purchased a new horn.  Soldered it into place and it activated every fourth dimension  when I touched the wire to the spiral on the top of the whistle relay.  Now the relay activates only the contacts don't ever create enough electric current (it clicks)  to activate the horn.  Should ane curve the contacts to improve connectivity?  Sand down the contacts to clean them up?   Is at that place any maintenance to the relay -lubricate-clean??  What has been your experience in ensuring a good diesel horn?  Is it even possible?  Thank you for sharing your experience and input.

Starting time verify that the contacts are the problem by touching them with your finger when the relay closes but the horn fails to blow.  If you can become it to blow by nudging the contacts, and so yous could effort cleaning with very fine sandpaper for a very brusque time.

The contacts are designed to rub slightly against each other when the relay closes, to go on themselves make clean.  And then farther cleaning should not be needed as the locomotive is used.  In fact, it may clean itself in the first place with employ without any intervention past yous at all.

I'm curious equally virtually mail war horns took a battery also. and with out the clicking is what you lot use to go. so my question is did you over look putting a battery in it. is it a postwar horn you bought or a new type horn? as it may accept a dissimilar type hook up than running thru the horn relay. What is the engine number to this engine? all questions so we can go a good thought on how to better help you. By the way you came to the right identify you have guys hither that are retired train repairmen to novice to ones at present doing railroad train repairs you have a lot of know how hither on this forum

My experience has been a slight adjustment of the relay tab can assistance...I wouldn't sand those contacts except equally a concluding resort (if they are totally black or burned).  I usually put a little Goggle box tuner cleaner on a piece of newspaper, concord the contacts together gently and pull the paper betwixt them several times to make clean the contact points.  If y'all have to sand them, piece of cake does it of course.

That lesser arm of the relay mechanism is pretty delicate, so less is more when it comes to adjustment.

Good luck!

Thanks for oyur response:

   Yes, this horn takes a d size battery and I did place one in the engine.  The engine # is a Prisoner of war Lionel 2337 Wabash.  I think i will try to lightly touch up the contacts on the horn relay.  Give thanks you.
