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
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.
