2 truck Heisler

I have recently acquired a Bachman Spectrum 2 truck Heisler no 81794, Oregon Lumber co
I am let to believe that it is DC but DCC ready, according to the box,
it came without any paperwork, being second hand and from a member who has gone to that great roundhouse in the sky.
At some point, I would like to fit it with a Massoth sound decoder.
my request is, does anyone have the relèvent documents, exploded view etc , so that I can take it apart to fit the decoder?
perhaps the documents could be scanned and emailed to me?
there is a very good video on YouTube about lubricating the loco but I cannot find a vid on fitting a decoder.
any other tips or hints on the loco would be much appreciated
thanks
Dave

Dave,

Have you looked here?

Thanks for the quick reply, yes I went there first , the 2 and 3 truck Shay and the Climax are listed but the Heisler is conspicuous by its absence !
Short of emailing Bachmann , I don’t know where else to go, I have looked on the internet quite a lot but not found the relevant info.
I understand that Bachmann are not the best at replying to emails?

Thank to Greg and Homo for the links, I now have a big pile of details To go through.
Interestingly, I decided to put the loco on my layout , mainly to see how much current it took to run it.
Hmmmmmmm! Nothing happened! I use Massoth DCC, I know some don’t recommend running DC locos on DCC but it should be ok for a very short while?
No!! We had fireworks from the front truck , it ran backwards for a few yards then stopped.
reading some of the above info, it appears that there is a noise cancelling circuit under the trucks, there being an electrolytic capacitor on the board. This must have been the fireworks.
I then tried the loco on a short length of track with an DC transformer, that’s where the ‘magic smoke’ appeared from!!, not the board in the back but from the switch in the smokebox.
nextstep is to investigate the boards under the trucks, the advise from the documentation above, is to clip out the capacitors if used on DCC…………watch this space!!!

I do love a challenge!!!!
 
You put the DC loco on DCC? Why do you think it would be ok for a very short while? The last electronics that would take a while to blow up were vacuum tubes, transistors and other stuff have little tolerance for abuse.

If you have an issue with the switch in the smokebox, it's most likely you have a major short in the electronics main board, that is drawing excessive current.

I think you need to do the "separation" of motor and track wiring now, like you would do in any DCC install.

Then debug the motor and track pickup circuits separately, using an ohmmeter, not live power.
