Lighting Connections
12-16V lamps can be directly wired to the function outputs as shown in
Figure 21.
Figure 21 - Wiring the Decoder for 12 Volt Lamps
If you are driving 1.5V microbulbs with your Tsunami decoder, it will be
necessary to wire a small current-limiting resistor in series with each of the
lamps to prevent them from burning out (see Figure 22).
A separate resistor must be used for each bulb even if they are connected
to the same output. A 560-ohm, 1/4W resistor is recommended for use with
SoundTraxx P.N. 810022 or 810024 microbulbs, however, you may need to
adjust the resistance value to get the desired brightness depending on the
output voltage of the command station. Lower resistance will increase the
brightness of the lamp.
Figure 22 - Wiring the Decoder for 1.5 Volt Lamps
1. To wire the Headlight, connect one end of the bulb to the decoder’s
WHITE wire. Wire the other bulb lead to the decoder’s BLUE wire.
2. To wire the Backup light, connect one end of the bulb to the decoder’s
YELLOW wire. Wire the other bulb lead to the decoder’s BLUE wire.
If you use Functions 5 and 6 for lighting effects:
3. To wire the Function 5 output, connect one end of the bulb to the
decoder’s BROWN wire. Wire the other bulb lead to the decoder’s BLUE
wire.
