connect the positive of the energy storage system to the plus
terminal (labeled things like V+ or +14V) and the negative ter-
minal to the minus terminal (labeled things like V- or GND or
the ground symbol). I suggest testing with a voltmeter before
you connect your module. Look for correct polarity and a volt-
age a couple of volts below your selected track voltage.
For SoundTraxx wrapped Tsunamis:
TSU-1000 –connect the positive from the energy storage sys-
tem to the blue wire, and connect the negative to the capaci-
tor black wire, not the black track wire. If you connect the
system where the external capacitor was connected, you will
only store energy for the processor and amplifier.
TSU-750 – Connect the energy storage system to the blue
and yellow/green wires, just as the instructions show for
the external capacitor.
For TCS decoders – observe the color code – TCS is consistent
throughout their product line. If the decoder has a black/white
stripe lead, that is your power supply negative. If the decoder
doesn’t have a black/white stripe lead, there is no power sup-
ply negative brought out. I don’t recommend digging into the
decoder to find the negative. But that’s your choice.
Digitrax sound decoders – just connect the energy storage in
place of the external capacitor.
I know this list isn’t comprehensive, but it should lead you in
the direction you need to go. When in doubt, dig out the volt-
meter and test.
