I phoned today.  Will be mailing the locomotive in for service.  Thanks.

Still waiting for a callback from Williams.  Thanks.

The seller said to check with Williams 1st so I'm doing that.  Thank you.

Thank you.  I may try to return it for a refund or exchange.  I'm afraid that if I fiddle with it I will eliminate my chances to return it without fixing the problem.  Thanks again for your suggestions.

There's no wire from the tender to the engine and it has center rail pick up rollers and wipers on the axles.  I have not tried putting them on the track unhooked and applying power.  We're in the process of moving and my layout is packed away.  I can use my grandson's but he's 100 miles north.  This is a new engine and tender.  The track was Fastrack.  Thanks.

The locomotive by itself runs well.  When the tender is coupled on the locomotive shorts out.  The tender itself doesn't cause a track short.  Other locomotives run well on the same track.  Any ideas?  Thanks.
