4-6-0 problems

[ngbobme]

Dear Bachmann (or others)

I recently received my 4-6-0 ( the undec, steel cab version) and when I took it out of the box and joined the electrical connectors, it ran fine. I exercised it for a couple of days and then separated the loco and tender to detail and decal them. When I reattached the two units, the loco went crazy. On DC, it runs OK in reverse but will not budge forward. On DCC, which will be the norm, it does not go in either direction under control and the decoder buzzes as it jerks backward on its own for about a distance of about two inches on about 5 second cycles. My DCC controller (MRC Prodigy Express) goes into "SVPA" mode with each jerk. Anybody have this experience or suggestions? It could easily be something that I inadvertently hit on the DCC keypad since I'm about as electronically minded as a cocker spaniel, but it is very frustrating. Other locos run fine on their assigned frequencies in all details. Help!

Just an update on my erratic 4-6-0. I took it into my local hobby purveyor and he ran some tests. It seems that the decoder was kaput. Whether it was something I did or defective from the factory I do not know. Anyway, it has a new decoder and I have reassembled it and it runs fine.
