I just bought an MTH CP C40-8W and it works in DC (analog mode) when I place it on my DCC layout it causes a short and the
system senses a fault and cycles on and off until I either remove the locomotive of turn off the power.
I am using a Digitrax DCS 200.
I was told the MTH locomotive would work on a DCC layout.
Has anyone seen this sort of thing before?
