  1. Wouldn't this question be far better posted on the MERG forum? Rather than a third party forum?? Many MERG members will on their forum offer views/comments/reviews!
  2. <Bigger sigh> No its not, because you selectively edited the post and removed that quote. End of comments.... I'll not bother here again!
  3. That's what I said isn't it? Or I thought i implied it? As I stated " Therefore the Auxiliary outputs cannot be used with Common return wiring" They can of course be used in total isolation, but they are not suitable for use with the common return! Which is what the question is about. Also worth remembering is that if these Aux outputs are used separately, they take power from the same supply that's feeding the rails. So it can become very easy to overload one transformer winding without realising it. Hence IMO a totally separate power source is better for each Aux needed. There is no reason where all the power sources are separate not to use common return for all track, all solenoid point motor returns and even all lighting etc it wished. So long as the return wire is of suitable wire size and all supplies connected to the common wire are totally separately feed.
  4. There are two dual secondary wound transformers inside. Each secondary winding feeds its own 'Track' output. So the Track side it is fine for common return. The problem comes when anyone tries to use the Auxiliary outputs (2 x 16v AC and 2 x 12v DC) with common return, as each Aux output is taken from one of the windings that is also used for the tracks. Therefore the Auxiliary outputs cannot be used with Common return wiring. Here for aux power - (Solenoid point motor feeding / CDU input, layout lighting, feeding a non mains powered train controller etc) you need a totally separate power source.
  5. While this topic seems to have drifted well away from the title, I thought I would bring it back! Faversham MRC has announced it has reluctantly had to cancel its 2020 exhibition due to have been held on Saturday 12th and Sunday 13th September 2020. We cannot under current government guidance/regulations host a show that allows for social distancing, food and drink to be consumed in a seated area by our visitors, arrange one way system or keep toilets etc free of possible virus infection. We hope to see all our visitors, exhibitors and traders in September 2021.
  6. That may be the cause? You say it tests fine on a multimeter, but have you checked just how much AC its pushing out on the DC Track terminals? Set meter to read AC volts >20 and connect to track terminals. Turn up controllers speed knob and read any AC volts at full speed setting.
  7. Gaugemaster WM1 will do the job as a stand alone unit. Or an old train controllers 16volt AC output. As too will a spare or new 18 to 20 volt DC ex laptop power supply, are all able to be feed into the CDU input.
  8. What are you using as the DC power source for testing?
  9. Look for Warm White LEDs that replicate filament lamps better. To reduce the brightness increase the series resistance value in Ohms. Either replace the existing resistor with a higher value one or add a second resistor in series to the first one. These have quite a good selection of Yard lamps This link is to their OO selection Link to Yard lights Don't forget that filament lit lights will get hot - very hot. LEDs run virtually cold. Also filament lamps will draw far more power per lit lamp, Typically between 4 and 7 times as much LED=10 to 20 milliamp and filament lamps = 40 to 70 milliamp each!) The Eckon EL-1 yard lamps are no longer manufactured and are very hard to find today. The Eckon yard lamps currently manufactured at this time is.... Link to On Line Models who make Eckon
  10. Hi Just realised you're a DCC user! As the question is in the non DCC area, I thought you were a DC (Analogue) user! You can use your two wire Bi LEDs using the DCC and point frog polarity. Have a look here Link to item Scroll down a little.
  11. Nigel is correct. They require reversing of polarity to change between red and green This could be done but generally it needs double pole double throw (DPDT) switching arrangement. I personally dislike having red and green point position indications on a panel. There are far too many LEDs lit and it becomes somewhat blinding and possibly confusing too? IMO all that is needed is one LED per direction (route) lit to show which way the point is set towards and not a second one showing its not set that way! Then its much simpler to wire and is like the real UK railway which never shows an unset light, only lit or unlit per route direction To note; real UK railways do not use green or red indications for point position either, they use white or a yellow indication! Red and green are reserved for signal aspect indications.
  12. Hi If you dont fancy soldering wires onto switches then these are a good option!,,, Pre wire solenoid point switch or perhaps... Switch with PCB and terminals I would always recommend obtaining a CDU from then onset, Cost isn't that much at around £7 GBP Example.. CDU example link I have no connection with the company linked at all, and of course there are other suppliers too. Wire all solenoid points in 16/0.2mm minimum or if you already have rolls of 7/0.2 double up each wire
  13. Whenever possible try not to solder droppers (regardless of their wire size) to the rails outer web area. They look unsightly! Instead and for an almost invisible look, solder them whenever possible to the rails undersides before laying the track. Passing them down to below baseboard via a centrally drilled hole between rails and a sleeper pair or if preferred by two small holes in line with the outer edge of the rails. I recommend at least a 25 watt iron and if possible a larger wattage, but fitted with a suitable sized bit.
  14. Possibly?.... Link to RS Components Note the DC plug does not fit directly into the PCP socket . It needs a converter. The PCP DC input socket is 2.5 x 5.5 positive to centre. The plug on this RS power supply is 2.1 x 5.5. Coastal DCC have one 15 volt 1.6Amp plug-in power supply suitable for the PowerCab Coastal DCC
  15. Never seen one in a commercial Toggle switch. Levers are of course different. But there is an option where a locking toggle switch can be used with solenoids. An example would be that each point has a On/On toggle switch plus its own dedicated non locking press to make push button. So the toggle switch provides the direction required and the PB provides the momentary pulse to the solenoid coil via the toggle switches contacts.
