AF 312 armature shorts only in reverse.

LKOGR Forum Member

Im a ogauge guy but I volunteered to clean up a flyer steamer. Would not run at all. I looked at eunit first, cycles and contacts okay. Took boiler off and brushes one brush was getting hung up. Still jamming. Cleaned gears and oiled. Now works forward great, but smoke or arc on armature plate in reverse. Does this mean armature shot or something else?
