Usually it is a challenge to cram all of the parts in but there was no shortage of room in the tender for the electronics in this tender. |
| The
speaker
I
used
is
the
same
one
used
in
many
Lionel
tenders
and
is
rated
at
2
watts.
With
the
large
size
of
the
tender
as
a
resonator
is
it
truly
awesome
sounding.
The
board
on
top
of
the
speaker
has
the
headlight
diodes
and
resistors. |

Due
to
the
enormous
size
of
the
Northern
and
it's
possible
extra
current
needs
I
decided
to
use
the
AC/DC
Commander
board
from
the
Electric
RR
Co. It is offered in a special combo version with both boards. Other manufacturers boards would also fit. |
| The antenna is very simple. It is a small piece of blackened printed circuit board cut to size to fit between the details under the tender. The program/run switch is mounted in the tender floor. |  |
 |
The chuff trigger switch and magnet are mounted on the rear truck. They are CA glued in place. I opted to mount the sensor in the tender for the sake of simplicity. The tender wheel ratio was so close to the smoke chuffer's that it did not make sense to mount it in the Loco although it could be done. |
| I left the original wiring as intact as I could. You can see the added motor bypass capacitor. |  |
 |
I replaced the original four pin connector with a six pin Molex type female connector and a double row dip header as the male connector. |
| Yes that is a working headlight in the tender. |  |
 |
This is a close up of the added golden white LED. Not too hard to add and it really should have been included in the production version in my opinion. |

Here are some details of the |
 |
| Here
you
can
see
the
six
pin
header
plug.
The parts for the connectors are from Mouser Electronics. 6 pin connector shell part number:571-874562 Connector pin inserts part number: 571-1021282 Double row header part number 649-68691-172 |

Here
is
the
wiring
diagram. I used golden white LED headlights but the original bulb will work too. |
