Slightly off-topic of this post but as the Bach-man is in contact here:

Can you advise me what the various Auxiliary connections on the Bachmann G828X DCC Adaptor Board make with the motherboard of the 2-6-6-2 Mallet? ( Smoke, cab light, firebox flicker, etc. ?) - ie: which pins on J1-12 & J2-12 connect to what functions on the Mallet?

Hi all,

I'm after a pair of side frames (or a complete truck) for a Climax - the side frames are not available on the Bachmann spare parts store and I want to make my Climax into a three truck locomotive (I'll scrath build the rest of the components).

Any help here would be appreciated.

Hi all,

I'm converting a Bachmann Fn3 Mallet to battery power with radio control.

I've got it working on the bench with a CVP Airwire CONVRTR-60X receiver and an ESU LokSound 5XL decoder (sound and motors) - lights, etc. have not been tested yet as the tanks are off during the setup process (and awaiting a custom battery to fit inside - but that's another story).

You cannot view this attachment.

I've chosen this combination as it is running successfully in the 3-truck Shay I posted elsewhere and I use LokSound in both this scale and my 1:48 work due to the ability to customise the sounds (the Mallet is running ESU's mallet sound file but with different whistles as I didn't like those in the factory file).

I'm wondering if someone can advise me what the various Auxiliary connections on the Bachmann G828X DCC Adaptor Board make with the motherboard of the loco? ( Smoke, cab light, firebox flicker, etc. ?)

Maybe I have missed this on the forum but I'd be grateful for some help.

Not essential as I can work through it by trial and error but it could save me quite some amount of time - once I know all of the connections I will post a PDF spreadsheet for others who wish to go down this path.

Any assistance would be greatly received.

LokSound 5XL and CVP Airwire conversion is now finished and the Shay has had many successful running days (lasting all day on the LiIon battery in the water tank).

Only "issue" is the sound stops if the transmitter and receiver lose momentary contact and the locomotive stops if connection is totally lost (I'm quite happy with that as I'd rather it didn't keep running without me knowing what it was doing).

Hi Kevin,

nice work - look forward to seeing it painted and weathered..........

is it dead rail with RC or DC track power?)

Hi greg,

thanks for the email - I have done this on a 1:48 scale installation in the firebox of a Wiseman Model Services Willamette winch on my "Winch #3 diorama) so I may go down this path.  I would post an image of this but apparently the upload directory is full....

The flickering ashpan and firebox are not really an issue when used outside - just wanted to see if I could get them to work (along with the smoke unit) without having a Bachmann cicuit board.

Probably need brighter LEDs than the ones I used in 1:48 scale.

Hi Bill,

thanks for your reply - I have not connected them to the decoder as there are no resistors on the boards and the wires were loose under the coal bunker (no circuit board).

I'm assuming there were resistors in line with the output connections located on the circuit boars but the Bachmann schematic doesn't show any circuit diagrams for the board (just wires going to various points on the board).

I assume the firebox LEDs are cooked by the color underneath them - in the absence of any help from someone who has done away with the circuit board I will put resistors in line with the LED inputs and see how I go.

I've just finished installing a LokSound 5XL into a wreck of a three-truck Shay that has no circuit board (see my post about firebox circuitry) with an Airwire receiver and a 14.8V LiIon battery and it is happily driving all three trucks on the rolling road as I write.

Will be few weeks before it is finished with fixing broken parts the first step, and then painting and weathering the way I do my 1:48 stuff (see Narrow Gauge DownUnder October issue for my "Winch #3" diorama and other forums).  This is my first foray into Large Scale.

I have a new Climax to convert the same way except I'm going to convert it to a three trucker (have 3D printed sideframes and Bachmann wheels as a start).

Hello all,

new to this forum and to large scale.  I'm rebuilding a wreck of a three-truck Shay which had the circuit boards removed and cut-off wires floating loose under the bunker when it arrived (supposedly setup for wireless control according to the eBay ad but was absolutely unusable when it arrived - the shop that sold it to me did do a partial refund when I sent photos of what was missing under the bunker and water tank).

I've just finished wiring it with an ESU 5XL decoder and an Airwire receiver after tracing all the wires including the loom to the water tank on the third truck (Bachmann colour coding changes in the loom to the rest of the engine when testing across the pins on the connector board).

All is working but my question is does any one have knowledge of how to wire both the ashpan flicker board and the firebox flicker board?

The Bachmann circuit diagram just shows the colour of the wires going to the main circuit board (which does not exist in my engine courtesy of the butchery done to it before) and does not show any resistors in line with the positive LED feeds.

The Ashpan board has 3 pin connections:

• Y1 - Yellow
• R1 - Green
• GND - Blue

The firebox board has four pin connections with no indication which is ground:

• Orange
• Brown (across 2 pin connections)
• Red

I'm not prepared to make any assumptions here based on colours - given both wires to the cab light are purple and the ashpan ground is blue!

I also think the ashpan board has been cooked by not having resistors in the positive feeds so I will probably have to replace the LEDS as well.  (the board doesn't appear as a spare part on the Bachmann site)

Any help would be appreciated.
