Has anyone on here got any experience with repairing the white locomotive to tender plug on Hornby and other models? I know you can buy as a spare part, the four-pin connector with wires attached and then solder that to the Loco but usually it's only one pin that needs replacing. I've seen you can buy the small connectors and the crimping tool online from places like eBay and Amazon What I'm not sure of is what size I need. I've included a few links to the products I've been looking at if anybody could tell me if these are suitable for Model railway use it would be very helpful https://www.ebay.co.uk/itm/134781932915 https://www.ebay.co.uk/itm/134708923115 https://www.ebay.co.uk/itm/335085754722 https://www.ebay.co.uk/itm/266159397039 https://www.ebay.co.uk/itm/385308446139
