Deem Posted October 25, 2022 Share Posted October 25, 2022 Hello I am sure so many would have done this, advised others and maybe share pictures or videos as well. However yesterday when I was looking I couldn't find anything so I am sharing anyway in hope some may find it useful. Hornby Class 08 NON DCCLiasDCC 4 Function NEM 652 decoderDCC 8 Pin Harness NEM 652 pre wired Hard wired the 8 pin harness first so in future if I can find TTS decoder I can just change the decoder.

Deem Posted October 25, 2022 Author Share Posted October 25, 2022 Decoder is mounted with black tac behind the front radiator. Video link showing loco running after DCC conversion.https://drive.google.com/file/d/1N2lTsRN4bwT6HIDy-j9g8yEa5tQe-h7N/view?usp=sharingThis one runs much smoother and better then, my other Hornby Class 08 with Hornby 4 pin decoder. They have identical motor, chassis with only 2 things which are different, 1st decoder and 2nd wheels, older model have traction tyres on middle wheels and newer model have no traction tyres.Regards Link to comment Share on other sites More sharing options...

Deem Posted January 27, 2023 Author Share Posted January 27, 2023 Hello everyoneJust small update to this Loco, my first attempt to put directional lighting in this loco as well. Link to comment Share on other sites More sharing options...
rpjallan Posted January 28, 2023 Share Posted January 28, 2023 Well done!And useful info too... Link to comment Share on other sites More sharing options...
96RAF Posted January 28, 2023 Share Posted January 28, 2023 There is a little rhyme to help when hard wiring.Red and black go to the track.Orange and grey go the other way i.e. to the motor.This obviously also applies if you are fitting a socket.

Fishmanoz Posted January 28, 2023 Share Posted January 28, 2023 Well done Deem. Hard to tell how bright the lights are in a photo so what value resistor did you put in series with the LEDs? Link to comment Share on other sites More sharing options...
Deem Posted January 28, 2023 Author Share Posted January 28, 2023 Thanks everyone from your kind words, as for what resister I used, I bought these from AliExpress with pre wired with built in resistor.The link is belowhttps://www.aliexpress.com/item/32896664335.html?mp=1 Link to comment Share on other sites More sharing options...
Deem Posted January 28, 2023 Author Share Posted January 28, 2023 I also installed 8 pins socket which I bought from eBay so I can have easy access for soldering a with correct wires.https://www.ebay.co.uk/itm/225190679667?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=1cwrJnXfTQ-&sssrc=2349624&ssuid=nIMs5JBBS9W&var=&widget_ver=artemis&media=COPY Link to comment Share on other sites More sharing options...

Deem Posted January 28, 2023 Author Share Posted January 28, 2023 Much better than the Hornby original fit socket.Bit bigger to install in steam Loco's body but in Tender, this is fine, or fine to install, if installing in Diesel or Electric Loco as well.

Deem Posted January 28, 2023 Author Share Posted January 28, 2023 I have made a video in dark to show what's the brightness of LED looks like. I hope everyone enjoys it.Regardshttps://drive.google.com/file/d/1oXZ3J-I_Sqv3kGFMk6zGrCUUldEfeI-z/view?usp=share_link Link to comment Share on other sites More sharing options...

Pity they don’t give the current draw though, that would have given the answer. Link to comment Share on other sites More sharing options...
Deem Posted January 29, 2023 Author Share Posted January 29, 2023 @Fishmanoz, I can try to use multimeter to see how many voltage or amp these led are using in dc mode and dcc mode. Would that seen to be correct way to check or I need to test some other way? Link to comment Share on other sites More sharing options...
Deem Posted January 29, 2023 Author Share Posted January 29, 2023 If there was a way to send you and if forum allows it (which we aren't allowed), I would happily send you 10 each, Red leds, white leds and yellow leds. Link to comment Share on other sites More sharing options...
Fishmanoz Posted January 29, 2023 Share Posted January 29, 2023 Deem, multimeter in series on 10s of milliamperes range will give you the current. Then 12 divided by the current gives you approximate resistor value. Link to comment Share on other sites More sharing options...

96RAF Posted January 29, 2023 Share Posted January 29, 2023 LEDs should only draw 10-20mA of current. The limiting resistor is there to achieve that value based on the specification forward voltage.If your meter is ranged on 10s of amps it will likely not read an LED current.

Deem Posted January 29, 2023 Author Share Posted January 29, 2023 I have option either 200mA or 10A. So i can try at 200mA to see if it reads anything tonight. Link to comment Share on other sites More sharing options...

Then 12 divided by the current gives you approximate resistor value. I have uploaded pictures showing the reading,Multimeter was set to 200u and reading was between 0.3 and 0.4I set the meter to 200m, meter would show 0.0I set the meter to 10A, meter would show 0.0.If follow your formula I will get 0.03333, don't what does that means, so any help will be appreciated.RDS Moderator Note: The pictures referred to are at the end of Page 2 of this thread Link to comment Share on other sites More sharing options...
Brew Man Posted January 30, 2023 Share Posted January 30, 2023 @DeemI would say the red lead on you meter should be plugged into the right hand socket and your dial set to the 200m range. Link to comment Share on other sites More sharing options...
P-Henny Posted January 30, 2023 Share Posted January 30, 2023 Deem,As Brew Man says, you have got the red lead in the WRONG socket on the meter. The red lead ONLY goes in that left hand socket when reading high currents up to 10 Amps. For the mA current that is typically drawn by LEDs, the red lead has to go in the right hand socket that is labelled mA and the rotary switch should point to 200m [= 0 to 200mA].

Deem Posted January 30, 2023 Author Share Posted January 30, 2023 I will change the leaf to volt to see how much voltage the led is using. My mistake, I thought to read resistance reading I needed to check this way. Thanks all for correcting me and hopefully we will get to bottom of this eventually.
