Troubleshooting
Wrong directional toots – Swap wires between C3:1 and C3:2 on the
Auxiliary Input Board, P5T, or change the track polarity using the
Computer Interface.
No Sound – Start by rechecking the wiring to the speaker, volume
switch, and power connector. A connection may have been missed
or become loose. Measure the voltage applied to the power
connector when you think the board should be on. 7 volts is
needed for the board to make sound. It may be something as
simple as the volume being turned down, try raising the volume.
Also check the volume switch and its connectors to make sure
there is no damage, broken connections or that the switch
terminals are not touching anything metal.
Low Volume – If the volume is lower than your chosen setting the board
may not be receiving full power at connector C1.
Erratic Chuffing – The axle magnets may not be mounted
symmetrically. Also, if the reed switch is not mounted to the truck,
the distance to the magnet might change during curves. The wires
coming from the reed switch might be broken or loose. Engines
with built-in contacts (Bachmann Spectrum) may require cleaning
or oiling of the contacts. Contact Problems are the normal cause
for faster then normal chuffing.
Whistle too frequent – The whistle plays based upon the speed reaching
the whistle play speed threshold. If the train slows down in curves
or at grades this may cause additional whistle triggering. Running
at a slightly higher or slower speed may help. If a reed switch is
used to blow the whistle, triggering may occur due to unexpected
magnetic fields such as those generated by the speaker. Make sure
your reed switch is not mounted too close to your speaker.
