Picked up a Bachmann Spectrum SD45 with a MRC AD350 chip installed. I do not have DCC (yet). When I put in on the track the lights come on but it will not move. My other loco's move fine. It should run normally on the track without DCC, shouldn't it? I'm thinking of opening it up and removing the chip but how do you get the shell off? Everything seems so fragile I'm afraid of breaking it. Any help would be appreciated.
