johnny wilko Posted January 10, 2023 Share Posted January 10, 2023 I'm sure this has come up previously but cannot find discussion. I have a few tender drives which often have problems with electrical continuity to the engine pickups. I have hard wired them with some success but would prefer to have a solution where the two are easily detachable. Has anyone come across an easy upgrade?

ColinB Posted January 10, 2023 Share Posted January 10, 2023 I just bought the two wire JST connectors off EBay. Generally they come with plug and socket attached to leads. Similar to what Hornby use on their latest locos, but they use the 4 pin version with a socket mounted on a PCB. Link to comment Share on other sites More sharing options...
Deem Posted January 10, 2023 Share Posted January 10, 2023 I bought 4 wires with plug and socket to run them from Loco to tender or vice a versa, link from Roads and Rails:https://www.roads-and-rails.co.uk/collections/sale/products/three-micro-plugs-and-sockets-4-pinVery handy.They have 2 pins, 3 pins, 4 pins, 5 pins and 6 pins as well.Regards Link to comment Share on other sites More sharing options...
atom3624 Posted January 10, 2023 Share Posted January 10, 2023 A couple of things to consider:Colour coded wires make sense, but look terrible - all black is best 'compromise'.Options include heavier duty wires, which make sense, except if you have a twisty layout, you'll probably be re-railing the tender quite a lot.Just something to think about.Al.

Topcat2018 Posted January 12, 2023 Share Posted January 12, 2023 Over the short distance between the loco and the tender the gauge of wire used is going to make very little difference to the voltage drop between the loco and the tender. There will probably be bigger voltage losses between the wheels and wheel contacts in the loco and tender. Better to use thinner, less obtrusive and more flexible wires.If you are using JST connectors it is probably best to stick with the pre-wired versions so you may be stuck with black and red wires anyway - unless anyone has found some with all black wires.

What About The Bee Posted January 12, 2023 Share Posted January 12, 2023 @TopcatA "Sharpie" permanent black marker will make swift work of colored insulation, turning the wires all black. Since I am not in the UK, I do not know if a "Sharpie" is known as a Sharpie in the UK. So forgive me for using a US trade name! I'm convinced, however, such marking tools do exist!Bee Link to comment Share on other sites More sharing options...

atom3624 Posted January 13, 2023 Share Posted January 13, 2023 True enough, but when I go to the stores, unless I have a preferred brand, size, I'll ask for a 'permanent black marker' - they'll purchase what's available.

81F Posted January 13, 2023 Share Posted January 13, 2023 Whats wrong with Sharpies? I've used them to "paint" straps on open wagons after applying my own private owner wagon transfers. Link to comment Share on other sites More sharing options...
atom3624 Posted January 13, 2023 Share Posted January 13, 2023 Nothing is wrong with 'Sharpies', I merely proffered a generic term.Like we use 'Sellotape' for transparent adhesive tape - many areas in Africa know it as 'Scotch'.What was the topic subject? :-)Al.
