Pin Out Connections to Bachmann Mallet Motherboard?

[David Price]

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).

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 as Bachmann's documentation (and wire colour coding) leaves a lot to be desired 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.

what the various Auxiliary connections

David, I have the PDF of the "Large Scale Plug/socket V2.1" which I can send you if you msg me your email. [Any way to attach a PDF here?]



I think you'll find the smoke-box flicker was never in the original spec, so it isn't defined. In my experience, Bachmann is a bit cavalier about what is on the board and what isn't. For example, the C-19 has a speaker installed but using a Crest Revolution (derived from the original Aristo spec,) the speaker isn't connected. We had to use the plug on the Revo board directly to the speaker. Best of luck!
