Lights
One of my lights is out
None of my lights are on
When I apply power to the
track my engine starts up
(lights and sound) but it won't
move
My engine hesitates at slow
speeds
Analog DC
Check for an obstruction in the smoke
stack
Add 10-12 drops of smoke fluid
Most likely you had been running the
engine in DCC or DCS mode and
toggled that light off. Put it back into
one of those modes and turn that light
back on. The engine will remember
that when you run it again in
Conventional DC.
Could be the same reason as "One of
my lights is out"
Is the engine getting power? Check to
see if there is voltage on the track or
move the engine a few feet in either
direction.
Check the Tender/Boiler drawbar
connection. You've got to have them
locked together.
Lower the track voltage then raise it
again. The engine should start
moving. If you apply greater than
9VDC quickly the engine will just set
there. Lowering it below 9VDC then
raising it will get the engine moving
Check the Tender/Boiler drawbar
connection. You've got to have them
locked together.
An engine may do this right out of the
box if it has not been lubricated.
Follow the lubrication instructions.
Now go ahead and run it.
New engines even after they are
lubricated may take a little bit to get
everything run in. Be a little patient
and let it run for a bit. It should clear
up shortly after lubricating and
running
Check to see if you have any kind of
binding on the side rods. There may
be a chuck of your favorite, perfectly
scaled pine tree stuck in there.
