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 apply power all of the lights do
not come on. Or the lights come on,
but the engine will not move when I
cycle the reverse unit.
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. See
the "Basic Operation" section for more
details.
The drawbar connector may not be
seated properly. Make sure the
drawbar is properly connected.
