WE just purchased a new 2-8-0 with Tsunami sound and the capibility to run on DC and DCC. WE tested it in the hobby store, it worked find on DC. Got it home and it was a no go on our track. We are running an MRC dual Cab Transformer with pulse and full speed switches. The loco just sits still with headlight blinking. After swapping to another transformer (single wired direct to cab 1) the loco worked and functioned as it should. What could be the problem? IS the pulse feature on this power pack a problem? Or is it the dual cabs? Or could this older transformer be putting out unclean DC that is causing the onboard electronics problems? All other DC locomotives we have work fine with the transformer.
