Appendix I Troubleshooting 98
36. The horn or whistle continues to blow
when the horn button is no longer pressed.
Or the horn, whistle or bell will go on and off
when no buttons are being pressed.
Also, when I enter RESET from a cold start, I
hear three dings instead of two. Or if I do a
normal three-second power down RESET, I
hear a “ding” after three seconds without
power and an additional "ding" when I re-
apply power.
Also, I am having difficulty selecting my
engines or other RESET choices and do not
hear the "ding" when I press the horn button.
An accessory, faulty transformer, powered car or some
problem with the engine is putting a DC horn or bell
signal on the track. The following may cause this
problem:
1) Right-Of-Way brass cabooses can be a source of
DC on the track since their lighting system draws
power unevenly from the track.
2) Faulty smoke generators in some new brass engines
can cause uneven power loading on the track. Turn
the smoke generator off to see if this solves the
problem. If so, replace the smoke generator.
3) Dirty AC motor commutators can be a source of
DC because of carbon build up. Try spraying the
commutator with TV tuner cleaner or and running the
motor for a minute or so.
4) Rollers are a source of DC on some engines
(Weaver RS-3, and FA Alcos) because the metal that
is used makes them take power unevenly, or because
of carbon buildup. Try cleaning the rollers before
replacing them.
5) Faulty track connectors and dirty track can
sometimes (but rarely) cause DC on the track. Try
cleaning the track and run extra power leads to
different locations on the layout.
6) Some electronic products that you may use in
engines or cars use a half wave rectifier. This will
cause DC on the track. Try turning them off or
removing them and see if this solves the problem.
Troubles in Neutral
37. Pressing the horn button to turn on the
bell or arm the coupler causes the engine to
go dead and it will not respond to direction
changes. You are not in neutral, you are in RESET. If the
power has been off for three seconds or more QS-2+
will automatically be in RESET when the power is
turned back on. If the engine has an ID #, it may be
de-selected when the horn button is pressed. Go to
RESET Position #0 and do an All Select (see Quick
Exit Guide above).
