KB538: Capacitors in Bachmann's Spectrum Steam Locos

This article was last updated on Aug. 17, 2011, 7:48 p.m. | Print Article | Leave Feedback

Q:  I have seen notes several times where the author recommends removing the capacitors that are in the Bachmann circuit boards before installing a DCC decoder. Can you comment on the need for this? Is it universal for the Bachmann steam locos?

A:  As a rule, all capacitors must be removed from locos before installing decoders. Also, any choke coils must be removed, too. Both capacitors and choke coils cause problems with DCC signals.

If you are unsure, a Google search for the locomotive type and the term "DCC" often produces an article specifically about the locomotive installation in question.
