Has anyone figured out the wiring of the lighting boards yet to fit a decoder??

"anzac1959"


this will be of some help : http://ca55ino.blogspot.com.au/2013/03/the-73s-have-arrived.html

I left a comment on his blog and as he states the markers are a big problem. I found they are switched on the lamp board itself . So that means you need to change polarity to change from white to red !something you cannot do on dcc. its either one or the other without auto switching.but if someone knows better im all ears.He is going to try 2 decoders.

Wolfman,

Apart from the wheel bases and bogie centres, Wiki gives this for the 73:

Engine power 700 hp gross (650 hp for traction) (522/485 kW).
Length over headstocks 10.97m Over buffers 11.99 m

For the Y class: http://www.victorianrailways.net/motive%20power/diagrams/ydia01.html

Rated horsepower 650
Length over couplers 43'3" (13.18 m)

Nothing in it if you ask me. Y class a tad bigger. One major difference is that the 73 is a diesel hydraulic whereas the Y is diesel electric.

Best regards,
John

Thanks for that info, too, nothing much in it at all, really! And apologies for 'derailing' the thread, continue regarding the 73 from Auscision! Embarassed
Speaking of, does anyone have photos of the 73's (and 422's, but that's another thread!) to share on layouts?

all three 73's I have have a loose panel on the top, it falls off literally. Thining of bluetacking it there - anyone else noted that?

Got my 73s great little locos and pull a decent load for their size.The small roof hatch is to access switches for headlight and marker lights,bluetac as you say or glue on if dcc wired.

Did the 73 have both red markers on when shunting yards?

And anyone know what happened to the 2 YouTube vids of the 73 shunting darling island ?

Sitting down with a pen & paper has revealed that getting red at both ends and still having the option of going red/white across ends won't be easy to do without modifying the pcb that the LEDs are mounted on. I'm still in two minds about whether or not to do this.

My question is about the number board lights. Are all four on simultaneously on the prototype, or are they switched end for end as per the headlights/markers? I've often wondered about this, as I'm sure that all the models I have with the molded plastic lenses for the number boxes aren't quite right as far as this goes!

Has anyone found out what decoder to use in the 73? and most of all how to wire it with the marker lights working?

There will be a how to guide in the next AMRM.

Or do as I did, I installed a NCE D12SR and will only be hooking up the front and rear headlights when I get my order from DCC concepts

No idea why but the YT user "DC 4916" took them off a fair while back. A copyright issue perhaps, I don't know, but it was a great bit of historical footage. When I've googled for the film all I can find re it's availability is to borrow it from the State Library NSW. FWIW, for the purpose of searching, title of the film was "Island Shunters".  Wish I paid more attention to the finer details when it was still online.

Edit: Just clicked on one of the uploads and there was a copyright claim by the filmmaker, Tim Woolner.

We used to leave all the number boards lights on (with red markers) when we were shunting in the various yards around Sydney, but only had the front number boards lit when working a train. If working a train with multiple units, then it still would be only the front boards on the lead unit that would be illuminated. Also used to leave the rear boards lit when running light engine, but cannot remember if it was a requirement or just out of habit.

I finally threw some credit card details Auscision's way for the first time and I'm more than impressed. Although I've been keen to grab hold of a 73 and 422 when they were first announced I let the idea slide until they were recently released.  Seeing some numbers quickly disappear and the need to throw some reverse schemes into my mix of locos I decided to get the current twin pack 422/73 reverse combo.  Whilst not a huge fan of the reverse scheme it looks fantastic on the 73. Either way, incredible detail on both, and great finish.  I'm really reluctant to weather any RTR loco these days.

Anyhow, quick question, exactly what are those big yellow boxes on a 73's handrails?

Thanks Raymond.  
Geez it seems pretty obvious now. I got it out of the packaging again and noticed the pipes coming down and the four boxes correlate to the four wheels each side. I didn't have a close enough look before.

Plus 1  .... I thought they were some kind of baffle, like the NR ones, but had me stumped .... So thanks Raymond.

Have just read through the convert your 73 class to DCC article in the latest issue of AMRM.

While a very concise and informative article has been provided, it certainly seems like Auscision dropped the ball with their 73 class model, sure its noted in the review of the model in the same issue that this model was built by a new / different factory for Auscision, maybe mentioning this they think they get a "get outta gaol" card.....

Here's hoping the 45 class does not go the way of the 73 where we have to alter the light boards to get things to work under DCC.....

Well, my 73 is currently on the workbench in pieces as I prepare it for a major transplant to become DCC. This will certainly require some work.
Maybe Auscision were not aware the light boards were wired incorrectly for DCC operation or possibly when they did find out it was to late to change and decided to ship it as a DC model leaving it up to others to sort it out for DCC.
  anzac1959 Chief Commissioner

Hard wiring it is not the hard part , the lights are the hard part to switch separately.I wonder how many people will ruin there light board trying to prise the defusser from the light board. I rang Auscision the week I received mine as I blew a marker led. There response was the factory didn't supply any spares(lol). PS the hand rails are also very fragile .

Just came across this:



http://www.youtube.com/watch?v=qCzfqmxQzPA

Maybe these "sugar-cube" speakers might be the answer to those of you who have a 73 that you want to add sound to?

Details are sketchy. Laurie mentions "TVW Minatures" as being where he obtained the speakers from, but their website doesn't indicate they sell the speakers....more so that they do decoder installations. I might add that I think his prices seem to be very reasonable too..... http://www.tvwminiatures.com/products.html

Well I finally sat down last night and commenced to modify the 73 Class ready for the installation on DCC sound. As we all know the 73 class is not DCC friendly due to the light boards and there are 2 options to convert it to DCC.
1) Install a decoder and only wire track pick-up and motor connections and forget about the lights. Approx. 15 mins work.
2) Modify the light circuit boards to make them DCC compliant then continue with the usual installation. Possibly 2-3 hours with sound. This requires above average soldering skills to alter SMD components.

Now option 1 is quick and easy but with the quality of our RTR model these days I feel why have a new release loco with the functions of a loco of 30+ years old, so I went with option 2.

Let me warn you.... this is not something that should be done unless your are confident with your soldering skills. I personally have not done something at this level before but I took my time and have successfully completed stage 1 of this conversion to DCC.

Stage 1: To modify the light circuit board. Thanks to Ben O'Malley for his hard work discover the problems and to produce an article in the current issue of AMRM will help describe how to do it.
I have used his guide but have made some changes.
Due to DCC function restrictions only 6 available unless a separate function decoder is added and I don't think there is room for 2 decoders, I have linked the number boards and headlights together to be directional with travel, now only 4 functions left for markers. In the article it appears the way it is wired that the number boards remain on at all times having a permanent GND wired to them. I guess this means the number boards will be on all the time the loco is on the track. Not what I wanted when it might be sitting in a yard.
I will be separating the 4 markers to 4 functions in order to have front and rear red markers on when shunting. This has its own problem as I'm using the ESU 21 pin decoder which only has 4 outputs and 2 logical. An adapter board is available but with space inside the 73 Class limited, it may not fit. However, once again thanks to Ben, he has a solution to this and requires more modifications.
For now I can say that stage 1 is completed and both light boards work the way I need for DCC.
Hints: Mark the (+) end on the SMD LED with a marker before removing as they are so small it helps when re-soldering them back on the board.
         Place a container under your work to catch the SMD LEDs. Remember you need to put them back and finding on your work bench could be hard.
         Don't use the soldering iron too hot. I had it set around 280-300 which was perfect to remove the SMD LEDs quickly with no damage.
         When testing the board on completion the markers have resistors on the light board but the headlights and number boards will need an external resistor on (-) function wire.





Stage 2: To modify the 21 pin adapter board ESU # 51967 for full 6 functions.
I'm working on that at the moment, waiting for parts.

Stage 3: Installation of adapter board, decoder and speaker.

Here some pics so far:

Nice work.

ESU V4 decoders actually have 6 function outputs now. You have to wire Aux 3 & 4 off the PCBA. See the Select manual for the solder pad locations.

Thanks Mansfield.

I'm using the ESU 21 Pin Select which has 4 control outputs and 2 logic outputs = 6. I need to convert the 2 logic to amplified controlled outputs. I thought the V4 were the same. Have they recently changed? I know the Select and Select Direct have solder pads for amplified controlled outputs for Aux 3 & 4.

The sorrow of this aspect of a new factory being used is the going back to old problems with wrong wiring in the models.  IIRC, this happened some time back with the Austrains X class, & I understand resurfaced with some other loco's as well. While they worked ok on DC, when some converted to DCC the wiring was wrong & blew the electronics.  

With the ongoing price increases of models of types, & the attempts to try & keep models affordable especially with detail & quality I think all the importers may be searching out places in China, possibly even to the Gobi desert & beyond finding new factories that can produce for a few $$'s less, which is understandable really but, it will mean the importers will have to really do their homework to ensure the new factories are aware of the standards needed, something the older importers have, in general learnt.

One thing that might also be better is having a standard wiring colour for each thing within a given range. What I mean here is some come with the correct colour coded wires and then you get one or two that it looks like the factory ran out of a certain colour wire and simply substituted whatever the had at hand spare. Make all models in Brand X the same wiring colours. And don't get me started on models that have all black wiring inside them either. Cut the black wire sure but which one.

Yes I know there is a standard for DCC wiring but a lot of manufacturer's do not use it in the models though.
