The release of the TSU-AT1000 decoder allowed an update to the installation examples to cover this decoder.

This is a fairly straight forward installation:

  • Remove the factory light board
  • Remove the factory LEDs from the factory light board
  • Install the factory LEDs with 1 K ohm resistors on the Tsunami
  • Screw the Tsunami down to the motor - insulate with nylon screws (the photo shows white styrene instead)
  • Put the speaker in the fuel tank and rout wires up to the decoder
  • Wire the track pick ups and the motor to the decoder

Sound Quality - While the speaker enclosure mechanism is NOT what Bruce would design, it works just FINE! Not to worry - follow the directions. Except, Bruce sees no reason for using a gasket - the speaker snaps into the Kato enclosure. Question - why didn’t Kato mold holes for the speaker wires into the enclosure?

Lighting - When programming the Tsunami, set the light type to LEDs and you are golden (white LEDs)!
