Have the above to do.
The tram has been modified with a DPDT switch, which appears to switch power to either smoke, or added GOW internal lights..
This unit has a small square circuit board with a 4-way bank on DIP switches, a resistor, a diode, and (I think) a ceramic capacitor on in. The is also a 6-pin header.
Have a 55021 to fit. - Which should fit in the bunker.
I reckon I can strip-out the switch, and wire the GOW bulbs into the decoder.
The smoke unit has yellow and brown leads, so need to work out what voltage that is. - I have the info somewhere, just not to hand!
Presume the resistor takes care of bulb voltage for fromt/rear lights, with the diode sorting out which way it is running??
Can use the decoder to switch the smoke unit on/off. - Check the voltage, and program accordingly.
Ditto for internal lights.

Does anyone have the connections for this small board? - Pickup/motor are obvious.. The 6-pin connector is not!

thanks,
Phil Partridge.
 
Here's how I did mine, Phil:
http://www.gscalecentral.net/digital-%28dcc%29/chipping-fiery-elias-now-all-completed!/

I junked the little factory circuit board and wired everything straight to the decoder - my install also used a Powercap Micro. Mine didn't have smoke - in fact I'm not sure that any of the tram locos have ever had factory-installed smoke, presumably yours has had it added along with the interior lights?

For the wiring layout of the 6-pin interface plug, if you want to keep it, see any Massoth XL or XLS decoder manual - they have diagrams for wiring up to an LGB interface cable.
As the Elias has front lights only and noting at the rear, I think they are always on regardless of direction of travel - at least that's how I've wired mine up using the Licht-I (interior) connection on the decoder.

Jon.

Edit: the 55021 has exactly the same pin layout as a Massoth L, of course, so the L manual should also show the 6-pin interface wiring and which pins on the 55021 they connect to; I think Muns (GRO) has the plug and cable for about a fiver.

Black and white wires = 5 volts
Grey and black wires = 18 volts
Yellow and brown wires = 18 volt
2 white wires = 24 volts.
 
Thanks for that Neil.. did not realise there were two sets of wires colours for the 18V units..

Jon, the problem with the 6-pin interface is that it never shows you the orientation.. If I used it, I could connect the cable either way round! - There seems to be lack of any standardisation between LGB, Massoth etc. in this respect.

I guess I will end up 'belling' out the (after market) switch, lighting and smoke installation, so pulling the original board will not add any extra complication to the job.

Thanks both for the information.
 
OK, I see what you mean, Phil - from memory of doing mine, the little circuit board just has the six pins for the interface plug and not an actual socket for the plug to go into - so I see your problem. Most other LGB locos that use the interface plug have the plastic socket with a notch in the side so the plug can only be inserted one way round. I'd just remove it altogether, it'll save buying an interface lead.... ;)

If it's any help on yours, that little rectangular enclosed speaker from Rapid that I used on mine works well and sounds fine, and fits very neatly down beside the boiler.

Jon.
 
Hi Jon,
Yes, the rectangular speaker is a nice fit.. I did another tram loco, where the existing decoder had failed.. fitted an LS from memory (four wires to motor/pickup) it fitted qite nicely with one of the optional ends snapped off.. Used a `standard` potentiometer for the volume control, mounted in place of the switch adjacent to the bunker.
Adapted it to look like a hand-brake.

Nice touch with the "handbrake" from the volume pot spindle! I may have to borrow that idea..... ;)

The LS decoder doesn't have snap-off tabs like some other Massoth decoders do - the components and plug sockets go right to the ends of the PCB - but it does fit very neatly in the bunker space as shown in the pics in my thread, just needs the four power/motor leads carefully bending up where they are soldered on, so they don't stick straight out from the end of the board.

Drifting slightly off-topic, the provision of the snap-off ends on some of the other decoders can be very handy for certain minimum-space installations - for example, if you take both tabs off an "S" module then it will JUST fit into the tiny coal bunker in the cab of an LGB feldbahn steamer, with an "M" driving decoder in the little designated space ahead of the gearbox!

Jon.
 
Jon,

That is good to know about the Feldbahn loco.. Can you just confirm which 'LGB' number you are talking about please? - I have one here, but think it is the little diesel.
You are welcome to use the pot/handbrake idea. that is why I posted it! ;)
 
Sure, Phil - I mean the little 0-4-0 feldbahn steam locos, LGB numbers 21140, 22140 and several other livery variants. There is a very small coal bunker in the left hand side of the cab, which is a separate piece and retained by a single very small screw under the cab floor. There isn't a lot of room inside, but you can just squeeze a "tabless" S in there as I mentioned, and then fix a small flat speaker under the cab roof with a ring of white-tack.

Jon.
 
I did the feldbahn loco. I fitted the HO Loksound decoder in the boiler section and in the coal bunker I put the speaker. I took out the coal bunker and with a drill opened up the side that goes against the boiler and this then allowed maximum sound out without anyone noticing the bunker was opened out. Sounds magic.
