[. . . ] IN LOCOMOTIVE STEAM CHUFF SOUND for various track power by Version 3. 8 volts) to maximize volume potential and battery life. When connecting the battery (DC) power leads be absolutely certain that wires connect to the proper DC input leads. If any connections are not done properly, especially the power connections, you will damage the sound system. The sound system is thoroughly tested and inspected before packing to insure proper function. [. . . ] Wiring for use with one of these amplifiers is contained with the amplifier instructions. Volume Control Speaker Output Speed Set This system features an optically coupled motor input sensor. This means that any connection to J3 pins 1, 2, and 3, do not electrically connect to any other power to the board!

If you care to use two 8 ohm speakers you must place them in SERIES. When connecting DC power to the sound unit be absoloutly sure that the "+" and "­" are connect correctly!If not, you will either burn out the sound unit or the supply feeding it.

Drawn as a SPST. 1N4002 or equivalent diode (item #374) If using a standard battery instead rechargeable, do not connect/use a resistor!of Battery Holders #579 - single 9 volt (shown) #652 - holds 6 AA #654 - holds 2 AA #578 - 9 volt battery snap connector Battery power - must not exceed 24 volts DC. Use one 9 volt battery or a string of 6 AA or AAA batteries (24 volt DC maximum input). Typical operation of most sound systems for one good 9 volt batteries is about 8 hours, AA or larger is well beyond 50 hours! Resistor needs to be calculated for battery type (you must know the charge currents of the batteries used) and maximum track voltage used. R = (Vtrk max - Vbatt nominal) / battery charge current This diagram allows for the use of rechargeable batteries. When track voltage exceeds battery voltage, the sound system will operate from track voltage and the battery will start to charge (when in the forward direction). If you need to charge the battery fully without the sound system on, place the locomotive on the track (with the motor not powered if present) and leave full track voltage on for 14 hours. The batteries will charge whenever the locomotive track power is set for the forward condition regardless of the sound system being on or off. They will not charge when the polarity on the track is set in reverse. When running in reverse, the sound system will only operate from the battery. A bridge rectifier could be used instead of a single diode alleviating this potential problem. ­+ 9V or 6-AA, or 6-AAA batteries For 12 - 14 volt maximum track voltage: 1 - Item #647 (8. 4v / 150mahr) rechargeable battery use 380 ohms (1/4 watt). [. . . ] 2 - connect Normally Open (NO) of the switch to the Black wire from the SYNC input. We recommend using optics since they can switch much faster, don't bounce, and do not interfere with the mechanical operation of the axle. Item #707, as shown, is a subminiature micro switch for this purpose, in lieu of using optics (0. 32"L X 0. 1" W X 0. 26" H). DO NOT use a leaf switch to the chassis (quartering lobe) this will damage the sound unit! BLACK 1 . . . . . . connect Black and Green optical pickup wires together, this then connects to the Black wire from the SYNC input. [. . . ]
