i got a light kit from creative railway engineering that installs in athearn six axle loco
it has fow and rev lights and strobe i installed it correctly but the loco now runs much slower
wheels and track clean. i am using mrc command control (loco in question does not have dcc) is this affecting operation why does loco run slower?
Does your loco sound different then before are not if so you might have wires rubbing the fly wheel on the loco.
