Great Northern Atlantic

Now it became electrical.
The whole wiring, lightning starts just here.
I use flexible thin stranded wire. And for optical reasons mostly ones with black insulation. The NMRA colours help you to assort which wire belongs to which pin, but between loco and tender i do not like to see multi coloured wires.
So it will be a little bit harder to wire them to the correct terminals, but the inconspicuous look is it worth.
Let me count what is needed on the loco:
2 wires from the pick ups from the rails
2 wires the the motor
1 wire to the front light
1 wire to the cab interior light
1 common
----------------
There are 7 wires from loco to tender. All these loco wires will end in an NMRA socket and wired according the NMRA rules.

For 3 of the wires i made an aditional terminal in form of a socket like in this example (0-8-0 USRA). So you are able to take the whole loco apart without soldering.

In the tender there will be another socket. This socket is fixed by glueing to the bottom.

Here are additional wires soldered:
Red to pick up, in this case to the bottom of the tender, current will flow from here to the non insulated wheels on the right side.
Black to the insulated wipers in the tender trucks of the left side.
Yellow to back up light.
Blue is common.
All these wire are soldered in such manner, that plugs and sockets can still be fitted.

The Tsunami Sound Decoders are delivered only with loose wires. Here i soldered a plug according NMRA rules to it.

Lightening of the Great Northern lamps.
The GN is sporting a very special sort of headlights.
There is not much room in it.
And they are brass in this case.
And brass has electric condutivity.
What to do?

First, buy 0603 type LED with flexible ultra thin stranded insulated wire.
Second, make headlight glass out of clear styrene sheet.
Third, glue the 0603 LEDs onto the inside of the glass, set aside an let dry.
Forth, drill 1mm hole into the rear end of the casing.
Sixth, drill another 1mm hole into the smokebox front rsp. the tender shell.
Seventh, paint inside of head light casings silver to imitate a reflector.
Eight, thread wires into the holes, not more difficult than contriving a thread into a sewing needle.
Ninth, glue the glass with the glued LEDs onto the rim of the headlights.
Tenth, solder a suitable resistor to one of the wires from the LEDs! I use 1,2Kohm resistors in conclusion with white LEDs.
Eleventh, solder a suitable pin to the other wire.
Twelvth, make trial and error which wire is which.
Thirteenth, mark the wires
Fourteenth, enjoy.

Were are the electrical wires?

The speaker. Here i decided to fix it onto the shell with the extra large acustic box. But had to make an additional plug - socket connection for it.

Still waiting for PSC parts.
