nSolder the positive (+) red wire from the battery
to the Charging Jack’s B terminal and insulate
the connection with heat shrink tubing.
nCut a 5”length from the remaining supplied red
wire. Strip and tin the ends.Solder one end to
terminal C of the Charging Jack.Solder the
other end to terminal #4 of the Power Switch.
Insulate both connections.
nSolder the positive (+) red wire from Sierra’s
Battery Connector Plug to terminal #5 of the
Power Switch and insulate the connection.
nCut a 9”length from the remaining supplied
green wire. Strip and tin the ends. Solder one
end to terminal #2 of the Power Switch and
insulate the connection.
nSolder the free end of the green wire from the
‘Speak1’plug (Step 6) to terminal #1 of the
Power Switch and insulate the connection.
nInstall the charging jack in the hole you drilled
in Step 8. The threaded shank of the battery
charging jack may not be long enough to go
through the thick plastic of the frame and have
room for the nut. We suggest using epoxy to
glue the jack in place. Be careful to not get any
glue inside the jack’s opening or barrel.
nInstall the Power Switch in the hole you drilled
in Step 7.
nAfter completing Step 11,skip to Step 13.
12. Installing Only the Power Switch
Since you are not installing the Battery
Charging Jack,wire the power switch as in
Figure 9. Insulate the soldered connections
with heat shrink tubing to prevent accidental
shorts.
nCut the positive (+) red battery wire in half and
strip 3/16”of the insulation from the ends of
each wire.
nConnect the wire from the (+) battery terminal
to terminal #4 of the Power Switch and insulate
the connection..
nConnect the remaining wire to terminal #5 of
the Power Switch and insulate the connection.
nCut a 9”length from the remaining supplied
green wire. Strip and tin the ends. Solder one
end to terminal #2 of the Power Switch and
insulate the connection.
nSolder the free end of the green wire from the
‘Speak1’plug (Step 6) to terminal #1 of the
Power Switch and insulate the connection.
nInstall the Power Switch in the hole you drilled
in Step 7.
13. Installing the Remaining Switches
If you have purchased a Remote Volume
Control Switch (P.N.810073), install this switch
in the hole you drilled in Step 9.
14. If you plan to install an optional Coupler Clank
Sensor Switch (P.N.810072) install it now using
the directions that come with the switch.
15. Trigger switches can be used to activate some
of Sierra’s sound effects by way of magnets
embedded in the roadbed.If you wish to use
this method of activating your sound effects
you will need to purchase P.N.810074. Included
is one trigger switch and one magnet. One
trigger switch is required per effect and one
magnet per location. If you plan to use trigger
reed switches,install them according to the
instructions that came with them.
16. Cut a 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 in front of the battery as shown
in Figure 10. Be sure to allow enough clearance
for the body shell.
