The answer to my previously posed question appears to be a change of circuit boards in the Vandy tender I wish to use with my Bachmann 2-10-2.   I find many references to the task of swapping circuit boards, but no information on the sourcing of these circuit boards.   Can I buy them from Bachmann?  I cannot even find a source for some of the tenders that come with the 2-10-2.    Thank you!

I swapped tenders on a new Spectrum 2-10-2 from a coal tender to a prevously purchased (but unused) Spectrum Vanderbilt Hicken tender.  The engine will reverse with the coal tender, but remains dead rather than move in reverse with the Hicken tender with dummy plug, or w/decoder.  Any suggestions?
