When I first turn the power on, the
engine will not begin to run. I
have to turn the throttle off and
then on again to get the engine to
operate.
When I press the whistle/horn
button, the bell comes on instead.
I can’t get the horn to blow when I
press the whistle button.
I can’t get the bell to ring when I
press the bell button.
The bell won’t work on a separate
bell button.
When I try to fire the coupler, FYS
starts.
The Proto-Coupler won’t let the
engine uncouple on the fly.
The coupler does not fire or stay
coupled.
When I press the whistle button,
the bell sounds.
Reverse the transformer leads.
You may be pressing the button
too quickly. Try pressing the
whistle/horn button more slowly,
taking approximately one full
second to fully depress the button.
You may be pressing the button
too quickly. Try pressing the bell
button more slowly, taking
approximately one full second to
fully depress the button.
Reverse the transformer leads.
Check the wiring of the separate
button.
You are waiting too long between
whistle button presses.
Try lubricating the coupler knuckle
with a dry graphite lubricant. Do
NOT use oil.
The coupler needs to be cleaned.
Wipe with denatured alcohol (not
rubbing alcohol) and let dry.
This is normal behavior. To
prevent accidental high-speed
start-ups, Proto-Sound 2.0 is
programmed to start up in neutral
anytime track power has been
turned off for several seconds.
