TROUBLESHOOTING
PROTO-SOUND® 2.0
Starting Up
Remedy
When I first turn the power on, the engine
will not begin to run. I have to turn the
throttle off and on again to get the engine
to operate.
This is normal behavior.
To prevent
accidental high-speed start-ups
,
ProtoSound 2.0 is programmed to start up
in neutral
anytime track power has been turned off
for several seconds. See the Basic
Horn/Whistle
Remedy
When I press the horn/whistle button, the
bell comes on instead.
I can t get the horn to blow when I press
the whistle button.
Reverse the transformer leads.
You may be pressing the button too
quickly.
Try pressing the horn/whistle but-
ton more slowly,
taking approximately one
full second to fully depress the button.
Bell
Remedy
When I press the bell button, horn/whistle
comes on instead.
I can t get the horn to blow when I press
the whistle button.
The bell won t work on a separate bell
button.
Reverse the transformer leads.

Try pressing the bell button more slow-

y,
taking approximately one full second to
fully depress the button.
Check the wiring of the separate button.
Bell
Remedy
When I try to fire the coupler, PSA s
tarts
.
The Proto-Coupler won t let the engine
uncouple on the fly.
The coupler does not fire or stay coupled.
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.
