Howdy all,
Broke into jail again. (And, yes I’m a newbie ). Took apart a late 1940s 6220 switcher. Before I put the motor back on the truck, all parts on the motor and truck spun smoothly and freely. When I stick thE motor back on the truck, the wheels only roll backwards (reverse direction). They will not roll forward when I try to turn the wheels. However, when I spin the armature, the wheels move in both directions. What did I miss?
