On30 / Forney Circuit Board Wiring
June 19, 2012, 06:39:10 AM
Hello all,

Wonder if anyone can help me?

I have acquired second-hand an originally 'sound fitted' Bachmann On30 Forney which has had all it's circuit boards and wiring stripped out and which has been converted back to non-sound 'DC'.

However, the two little green circuit boards have been supplied with it, with a mass of loose wires still attached to both (no 8-pin plug).

Does anyone (possibly Bach-man?) know if there is such a thing in existence as a wiring diagram for this engine, so that I can re-instate the original DCC circuit boards and sound? I have an 8-pin plug to hand and am quite competant with wiring, so all I need is to know what wires attach to where on the two circuit boards and which where on the boards to connect the various wires from the pick-ups and motor.

Thanks in hope.

HO / Can anyone help with a Bachmann British question?
December 28, 2011, 08:05:04 PM
Hi there,

This is really aimed at any users of Bachmann British 'OO' Scale who aremembers on the board.

I'm trying to establish the overall length of the Bachmann Class 105 2-car Diesel Multiple Unit (DMU) train, also ditto for the 2-car Class 108 DMU, and if anyone knows it, the overall length of the forthcoming 'Derby Lightweight' DMU.

I appreciate you guys in the USA probably won't be able to help - but thought it worth asking anyway just in case, as there is no similar forum for Bachmann UK.

Thanks in hope,
Don Mason

On30 / Bachmann 2-8-0 Head Light Failure
April 22, 2009, 03:58:27 PM
Anyone have any experience of curing faulty head lamps?  I have a problem with the 2-8-0 (lamp on front only in my case) but assume all of the DCC ready Bachmann Locos will be similar.

I am using a Soundtraxx Tsunami just plugged into the 8-pin socket on the Bachmann 2-8-0 circuit board and everything works fine - except for the head lamp, which originally worked OK but suddenly went out without warning after just a week or two of use.

I have replaced the lamp itself (with no success) and I then established that the original lamp is in fact still working fine anyway (on another loco).

I have traced the wiring right back from the lamp, through the connections in the ash pan and all the way back to the printed circuit board in the tender and have checked all the connections and solder joints. Everything seems fine so far as I can see - but still no head lamp.

The Tsunami itself seems fine, so I have ruled that out.

Anyone have any ideas? (I was going to say 'bright ideas' but that would have been a pretty rotten pun!)

On30 / Forney struck dumb ??
April 08, 2007, 07:42:59 PM
Hi gang,

It's been a while since I posted anything - been too busy lately layout building / laying track.

Can anyone throw any light on this?

I bought 3 'noisy' Forneys, have never run any of them other than a few times up and down a straight length of test track, as I am only just getting round to permenent track laying on my new layout.

So none have run for more than about 20 minutes in total.

However, one of them has just been struck dumb - unexpectedly and instantly - without warning.

One minute - absolutely fine, the next, total silence.

Everythng else is working fine - power, headlight, etc. I've tried resetting the decoder (successfully) - but it's made no difference ...silll no sound.

It does give the occasional strangled moan for just a millisecond or so if I try to blow the whistle after first switching on - so it's not a blown speaker.....but that's as far as it gets.

I do have to say that I'm a bit teed-off at having a loco struck dumb after little or no use.

Anyone got any bright ideas as to what the problem could be - or has anyone else had this happen?  It's got me totally mystified (and not a little annoyed - after all, I couldbuy a dumb one for a lot less money).

General Discussion / Sorry Guys
February 12, 2007, 10:33:11 AM
Sorry Guys - but don't like the new board format at all.

On the old board, I found posts in various scales and gauges to be of interest and it was easy to see the suject of ALL posts at a glance, therefore making reply very easy.

This new format is a minefield, taking MUCH longer to dive between different scales, different subjects, etc.

Far too complicated I think.
