*** I always wonder why things like the express models lighting kits sell.... Having looked at them and corrected a couple of miswirings for buyers who tried to install them, they are no easier than simply adding seperately bought LEDs!

It sound like this kit is arranged with each light set totally separate, but you can "automate" all lighting if you wish.

If you want automated lighting then one (front end) headlight and opposite end (rear) lights should be connected to the front light function (white - and blue +). Each light (red and white) should have its own resistor as red and white need different values (which as this is an express kit I presume is already done).

Ditto for the opposite end head light and opposing tail light, which should both be connected to the rear light function (yellow - and blue +).

*** No problem Alan - Once this one is done you'll be away and the next few will be easy. If you get stuck, just ask on list or PM me if you prefer

*** Don't give up, but take your time... It doesn't sound good that the loco running is affected now... if you can take a photo it may help but no promises... If I was closer I'd suggest you sent me the loco to look at. (although you'd be far from the first to send one to me from UK - we do specialised install work all the time for UK customers)

It occurs to me: Is it the blue deltic? - if so it is a 21 pin loco, so I presume that you have an 8 pin decoder via an adapter?

If so, only F1 and 2 (lights front and rear, or white and yellow) are actually connected directly via the adpater - to activate others (f3 green and F4 purple), it needs links added to the adapter PCB... and this is not documented properly with the bachmann adapter.

QUOTE (alan p @ 16 Feb 2009, 03:15) <{POST_SNAPBACK}>Now everything is going wrong. I have just noticed that it doesn't run smooth at low speed in one direction and it shorts in the other direction! I have checked the wires and nothing seems to be touching. It only shorts when I start to move the loco.

Maybe I'm not cut out for this digital buisiness...

and I still don't have the rear lights.

I wired the lights up matching colours from the decoder like it said in the instructions.

Would it help if I took a close up photo so someone could check the wiring for me.... ?

I'm getting really fed up now

It looks OK as far as I can see, but why is that second inductor (whe wire coil thing) discoloured???? - has the Express PCB been resting on it by any chance?

Also - what is the dark patch between blue and yellow on the express PCB - not a bit of solder I hope - if so, cut it away.... its shorting the connon + and yellow wire!

The whole of the express PCB copper is exposed as are the pads, so really needs properly insulating from everything else, especially the other PCB.

Also, remove C1 from the PCB along with any other capacitors fixed on the motor.....

----------------------------------------------------------

With it set up that way it is in the photo, you will at the very least, need to configure four functions to operate.

These will not necessarily be f0, 1, 2, 3 as it will depend how the decoder was set up by whoever programmed it. You will need to be sure that there is no conflict between which button operates which sound too - for example, if F1 turns sound on, it cannot also be used as a lighting function.

So... you have two choices - a complex re-organisation of the CV's to non-sound functions for lighting use which allows for the sounds to stay as they are OR a re-jigging of the sounds to free up 4 early functions for lighting only!

You really need a lot of patience or the LokProgrammer to do this easily - or send it to a sound expert to do it for you

OR

change the CVs so that all 4 lights are directional and on/off via F0. Same really - or send it to a sound expert to do it for you - Loksound manuals are awful for the casual user to understand (poor translations / not enough info) so messing with the Function CV's needs a lot of care if sound isn't to also be mucked up.

***ESU can repair the chip for a fraction of the cost of a new one. Either take back to the source and ask them to arrange repair OR Send it direct to ESU by registered post (they can occasionally tend to lose things :) ) and include a no value customes declaration if one is needed within the EU as they are twitchy about customs clearlance costs.

Include card detail and if you can, a reciept - if not, tell them the date it wa bought... they are pretty good about those things... They can be slow but it will come back 100% good as new for quite a low cost.

I install very many chips and to be honest I never find it much of a problem, but I do see and fix faulty attempts for customers - usually its simply something not properly soldered or insulated - a moments carelessness that didn't fault when the body was off but shorted when the pressure of the body pushed the added item - like your express PCB, onto other electronics.

Don't give up - simply become very cautious, double check each part of the curcuit you are making and insulate with heatshrink or similar at every opportunity...

*** Hi Alan

Its usually a silky smooth loco so something is not right.

As I said earlier, shame you are not closer so I could take a look at it for you. replacing things like the loco PCB are not likely to be the real fix... there is so little there to go wrong anyway. You COULD try replacing both the coils with a bit of plain wire - they do B all under DCC anyway, being part of the loco's DC suppression circuit.

When U get the sound decoder back then if you like I will make you an offer I would not often want to repeat too often.

Because I'd like to learn what your problems were, if you bundle up the returned decoder, the lighting kit and the loco and post to me, I will professionally install them for you and fully configure the lighting for you for the cost of return postage plus $A20 which will cover consumables and probably replacement LEDs all round. This is less than 20% of the standard cost.

I make this offer ONLY as I am always curious about such problems and want learn why its let U down... and of course, to help.

If U want to go ahead PM me and I will send U my company address details. turnaround would be several weeks as I am reasonably snowed under (80 plus loco's on the shelf awaiting my attention!!) right now.

regards

Richard
