wisstle on a 6466 tender is sucking 3 amps

[Cacau]

Hi ,

My tender's whisle works by itself on the track. When I run it together with any of my locomotives, it will only work in top speed.  I use a 1033 transformer, and it didn't use to be this way.

It appears the whisstle is using a lot more power than it used to. I opened it up, it turns freeley, and I also lubricated it.

 

Any ideas?

You seem to be describing a problem with your model train, this is a site for OLD trains of the PROTOTYPE size.  There is a model RR site here at Trains forums, you may get the response you seek there.  AA

You may try giving it a good cleaning. I'd start with the wheels and pick-up rollers, then move under the shell. Remove the brushplate and clean it, along with the face of the armature. Clean or replace the points. Check to make sure the relay contacts are clean, if not, use a piece of emery paper to clean them.

If you do a search for whistle tenders on forum, you will find a wealth of info. on postwar whistle tenders. Hope this helps.

Cacau,

Along with cleaning the tender inside and out clean your tracks!! I had a whistling tender problem and it was two-fold, the tender needed cleaning both wheel sets, center roller wheels and motor inside, also need to clean your track or the problem will be back in about two months. If you have a smoking locomotive you need to clean the track more often, even modern smoking locomotives leave a small residue of oil on the track.

I doubt that improving the electrical connections will help with excessive current draw.  There's a chance that your whistle motor has shorted turns in the field coil--not easy to fix.
