       Possible problem with whistle tender
       By: Bobbo Date: June 13, 2020, 8:40 pm
       ---------------------------------------------------------
       I have two whistle tenders, 2671W and 6466W that I am cleaning
       up. The 6466W works great, but the 2671W whistles okay until I
       power up to maybe 75 - 80% throttle. From there to full throttle
       it stops whistling because the whistle relay drops out. If I
       release the whistle control, the relay will pull in but will
       immediately drop out. No problems at lower throttle. Again, no
       problems with the 6466W across the entire throttle range. I am
       using a KW transformer with nothing else running.

       Make sure the whistle relays are clean and the bottom contacts
       are free to move. Clean both contacts on the relays with a fine
       emery board to remove any dirt or corrosion. Confirm the
       contacts are touching each other squarely and firmly when the
       relay pulls in.
       If the problem persists after cleaning, swap out the relays and
       see if the problem follows the relay. If it does, the relay is
       faulty and needs replacing.

       Thanks for the suggestion Larry. I have a lot of other cleaning
       and maintenance to do on my collection, so it will be a while
       before I try swapping the relays, if it comes to that.
