connector straight out. Excessive force may pull
out the wires or rip the mating connector off of
the circuit board.
19. Cut one piece of double-sided foam tape (or
Superlock fastener) approximately 2” long. Peel
the backing off and place on the Sierra board
on top of the large chips on the side opposite
the terminal blocks. Peel the remaining backing
off of the tape and place on the floor of the
locomotive next to the battery as shown in
Figure 11. Be sure to allow clearance for the
body shell.
20. Attach the cab and body shell to the frame and
replace the screws. Attach the sideframes to
the trucks and tighten the screws.
21. Make sure all the wires are tucked inside the
fuel tank and there is nothing “pinched.”
Replace the fuel tank with the securing screws.
22. Place the locomotive on a section of track. Turn
the power switch ‘on’. Note that the Sound
switch on the underside of the locomotive
must also be set to ON. You should hear the
engine start up. Slowly apply power. You should
hear two short horn toots as the locomotive
moves forward and three horn toots as the
locomotive moves backward. Make certain that
there are no short circuits detected. If horn
signals are reversed, switch the wires to Sierra’s
terminals 7 and 8. As you increase the throttle,
you will hear the engine RPMs increase and the
bell will come on. Refer to your owner’s manual
for programming.
Enjoy your SoundTraxx equipped GP30!
