Aristo-Craft GE Diesel DC
Installing a Dallee DCv3 auto-horn Sound System into an Aristo-Craft GE locomotive.
1 - Reed Switches - locate and prewire the reed switches as shown.
Since they both connect to a common wire, only 3 wires are needed
between them and the sound board.
3 - for ease of disassembly, a 3 pin connector, item 521, was used
between the fuel tank and bottom chassis. A hole is needed in the
chassis for these wires. Make sure it is deburred properly.
2 - Since one reed switch controls the Horn and the other controls the
Bell, they need to be mounted on opposite sides of the chassis. These
are shown below, attached with double sided tape (item 388), inside
the fuel tanks end. To keep things consistent, we used the right side of
the engine for Horn activation and the left for Bell. By wiring all engines
the same way, it is easy to know which side activates which function.
Note: You may want to test the activation distance for the reed
switches before final assembly. Since not all reed switches are made
alike, some will activate at a very low magnetic field strength and
others at a higher strength. The higher strength isn't the problem as
much as a lower strength. A lower strength reed switch might activate
from a magnet located on the opposite side of the rail (from a far
distance). This is tested by using an ohm meter to test for closure of
the reed switches or by wiring to the sound system and passing a
magnet for the opposite activation.
Basic Reed Switch wiring to the sound board.
4 - attach the track power wires and appropriate materials for the track
power pickup (J1 and J2) as shown in the main instructions. An easy
installation of the rechargeable 9v battery (item 647) with a 9v battery
snap connector (item 578) is easily accomplished with double sided
tape (item 388) as shown.
5 -A sound on/off switch (item 524) can be easily mounted by drilling a
small hole in the shell as shown. Place it in the same direction as the
other switches. This way the "ON" position will be easily known.
6 - as can be seen above, the sound board is easily mounted in the
switch access roof panel. It not only clears all of the other switches
when mounting this way, but access to the volume and notch setting
controls are easily accomplished. As can be seen, all wires to the
sound board pass through the existing openings.
7 - connecting J3, the motor input sense wires. In this application, we
decided to utilize the motor switch that already exists instead of wiring
the motor leads (white and black wires from J3) directly to the track
power pickups. By wiring this way, when the motor switch is set to the
"OFF" position, the sound systems prime mover will merely sit at idle
when the track is powered instead of ramping up/down to the applied
track power. This makes for a more realistic installation so that the
engine can sit fully illuminated, or not, with the sounds running at idle.
You can also leave track power on to fully charge the battery if
necessary without running the locomotive. If you don't care to hear the
sounds, merely turn the volume control fully CCW.
J3 pin 2, Black wire.
8 - Connect the other track power wire (shown as a black wire). As
shown, this is the other track power wire. The sound unit's J1, pin 2
connects to this point or to the "SOUND PWR" connector.
J3 pin 3, White wire connects to the other motor/track power lead which
is the same as the red motor wire or Sound Power
as shown. J1, pin 1, also connects to this point.

9 - either carefully solder speaker connector wires from the sound
system's connector to the main pcbd or the existing speaker. Or utilize
the "SPK" connector to connect the speaker wires.
