due to tolerances, it is useful to place some kapton tape under the decoder in
front of the motor tabs to make the fit more snug.
3.For this installation the factory 18mm x 10mm speaker is mounted in the
upper rear under the decoder, as shown in in Figure 2.
Before mounting the speaker under the decoder some kapton tape should be
placed over the frame halves so the silver conductive disc on the speaker back
will not short when installed. The speaker can be slid under the decoder until
located as shown in Figure 2. You can optionally remove the white tape from
the speaker to stick the speaker in the correct position against the decoder.
Dress the speaker wires so they do not get in the way of the shell and do not
short to anything.
4. (Optional) Functions for other lights etc., may connected to the pads identi-
fied in Figure 3. These function leads effectively switch the track voltage, so
LED's and 1.5V lamps will need current setting resistors installed externally, as
required.
5. In this SD60 installation the included insulated 100uF/25V electrolytic ener-
gy storage capacitor will fit inside the frame and shell in the cab location
shown in Figure 2. For other locomotives it may be possible to create space to
accept this or another capacitor elsewhere. Place kapton tape under the capaci-

tor and make sure that the capacitor case and leads do not short to the frame,
or damage to the decoder will result.
6. Inspect the installation before testing the sounds and replacing the shell. In
particular ensure motor tabs make proper contact with the PCB slots and do
not short to the frames, and the power tabs connect to the castings.
