DIRTY DIESEL Posted March 29, 2013 Share Posted March 29, 2013 Hi All, I’m on my second unit, as the first one only had one cab light working so it went back. I received my replacement and all was ok when running unit in on DC, but soon as I chipped it (all done very carefully) same problem again only one cab light works. Am I missing something are the cab lights on different function buttons? (Bachmann 21 chip fitted) Or have I just been unlucky, as the marker/head lights work ok at both ends I’m probably going to keep it as I don't tend to use the cab lights. Just a bit confused/disappointed that this should happen on such a good model. Thanks Stu Link to post Share on other sites More sharing options...
RMweb Premium Gwiwer Posted March 29, 2013 RMweb Premium Share Posted March 29, 2013 This is one powerful little beastie! I set up a loaded test run and kept adding more and more vehicles as she strolled away with everything I put on the hook. In this clip the unit pulls smartly away and accelerates load 36 and will clearly manage more. There are a couple of spots where the train slows down but responds to more power being applied; one is where the 128 has reached the start of a gradient and the other is where it enters the long sweeping curves above the cliffs and beaches. At the end of the clip the 128 is actually heading back towards my position on the opposite side of the layout but has the entire train moving up hill and around curves without a problem.

SRman Posted March 29, 2013 Share Posted March 29, 2013 That's very impressive, Rick. It certainly has power at least equal to any of the Heljan diesel locomotives! At the other end of the scale, here's a more typical parcels consist. Link to post Share on other sites More sharing options...
RMweb Premium Gwiwer Posted March 29, 2013 RMweb Premium Share Posted March 29, 2013 Those images look a lot more typical of the workaday 128s Jeff. Mine has found a pair of Hawksworth vans look good in tow among other short formations. Link to post Share on other sites More sharing options...
SRman Posted March 29, 2013 Share Posted March 29, 2013 I based mine on a photo I found - needless to say that it doesn't even notice that it has a tail load behind it!! I am sure I have seen pics of Hawksworth, Stanier and Gresley vans behind these, as well as the BR and SR types. The model looks good with any of these, I think.

RMweb Premium Gwiwer Posted March 29, 2013 RMweb Premium Share Posted March 29, 2013 Agreed Jeff. Any of the above. Plus DMU passenger cars as well though Heljan and Hornby don't run at all well together meaning I can't successfully pair the 128 with the bubblecars. Works a treat with unpowered Lima cars though. I'm definitely struggling to not buy a blue FYE one. Link to post Share on other sites More sharing options...
SRman Posted March 29, 2013 Share Posted March 29, 2013 Now there's an idea! I have several Lima units that I could easily 'de-motor' to form dummy units the DPU could multiple with (ie haul or propel!). Link to post Share on other sites More sharing options...

Both cab lights work on different function (F1,F2) so you will need the new Bachmann 21 pin decoder ( which I had other problems with ) or a Hornby Sapphire ( No problems ). As long as the decoder will handle 3 lighting functions you should have no trouble. Link to post Share on other sites More sharing options...

Hi John thanks for your reply, Iv got the old Bachmann 21 pin chip in it at present but I do have the newer version will swap them around and see what happens, I did read up on the newer Bachmann 21 pin one and its problems, hence why I put the old one in. But have had another read since and feeling more confident in the speed curve programming now. Stu Link to post Share on other sites More sharing options...
SRman Posted March 29, 2013 Share Posted March 29, 2013 Mine has the newer 36_557 decoder fitted and all seems to be OK. I have not yet experimented with the various speed curves but I have altered the inertia/momentum settings on CVs 3 & 4. Link to post Share on other sites More sharing options...
RMweb Premium Gwiwer Posted March 30, 2013 RMweb Premium Share Posted March 30, 2013 SWMBO just walked into the office and asked "Where did you take that picture?"This is the image which was on screen and which had her fooled despite knowing the layout very well. Standing a couple of metres back from the screen she wasn't convinced it was taken here! Link to post Share on other sites More sharing options...

Does anyone know which way is forward? Exhaust end or the other? And does anyone know the CV for dimming lights as its not CV63 on the newer chip Thanks Stu Link to post Share on other sites More sharing options...
RMweb Gold Oldddudders Posted March 31, 2013 RMweb Gold Share Posted March 31, 2013 And does anyone know the CV for dimming lights as its not CV63 on the newer chip CVs 49 & 50 seem to be quoted for "Lighting Control" but only have values of 0 & 1. CV59 is said to be "Lighting flash rate" which sounds like beacons. Fiddle around with other CVs in that area to see if any works. If you feel really brave, try to make sense of this, which is all about the zillion combinations of flashing lights US diesels use, but may also apply to the Bachmann decoder, as it is a Soundtraxx product. http://www.soundtraxx.com/manuals/mc2usersguide.pdf Good luck!

mevaman Posted March 31, 2013 Share Posted March 31, 2013 For anyone operating these units with DCC, you will need a 4 function decoder. Therefore the new Bachmann 36-557 and Hornby Sapphire are suitable. If you fit a 3 function decoder one of the cab lights will not work as there are not enough functions. Hope that this clarifies some of the queries. Link to post Share on other sites More sharing options...

StaffsOatcake Posted April 1, 2013 Share Posted April 1, 2013 I have just purchased one the early blue DPU and got the shock of my life when I came to fit the DCC decoder. On the box it says 21 pins, but mine definitely has a 22 pin socket on to which you can't fit a 21 pin chip. Now I'm stuck as what to do. Nipoff the offending pin or return it to the ratiler Link to post Share on other sites More sharing options...
Baby Deltic Posted April 1, 2013 Share Posted April 1, 2013 Maybe pin 22 is not connected on the PCB tracks on the DPU. Link to post Share on other sites More sharing options...

I'm not sure thats a gamble i'd like to take! It would be sods law that i'd snip off pin 1 Link to post Share on other sites More sharing options...
SRman Posted April 2, 2013 Share Posted April 2, 2013 Does anyone know which way is forward? Exhaust end or the other? Thanks Stu Normally I would have treated the exhaust end as the number 2 end as it is usually the trailing end of most DMU single-ended vehicles in service. However, when I fitted the decoder, the default forward direction has the exhaust end leading, so that is what I have settled on for now. As for StaffsOatcake's problem, I hope that it was a one-off error from the factory. My own definitely only had 21 pins and caused no problems with decoder fitting. I can only suggest what has already been said: that is, return to the retailer for exchange or snip off the offending extra pin, after very carefully identifying which one it is. Early issues of Dapol's class 22 had this problem and they gave very clear instructions on which pin to snip off. Link to post Share on other sites More sharing options...
RMweb Premium Gwiwer Posted April 2, 2013 RMweb Premium Share Posted April 2, 2013 As per Jeff's comments the 128 should have a 21-pin mounting. Dapol found to their surprise that the 22s were fitted (wrongly) with 22-pin ones and rather than have them all sent back for rectification and who-knows-how-long to wait for re-delivery they (via Dapol Dave of this parish) provided instructions on which pin to clip off. Anyone remember where that post went? Possibly in the class 22 thread? Link to post Share on other sites More sharing options...
