zedcell Posted August 3, 2019 Share Posted August 3, 2019 Hi all recently noticed one of my Hornby hst directional lighting was not working so removed body shell for closer inspection it's the one with the spring contacts under the cab. On closer inspection all wiring connections look ok . Placing the spring connections on the 3 connections I can get the red rear lights to come on but not the front white so before I do a factory reset on the ESU V4 decoder has anyone got any ideas of a posible fix.

zedcell Posted August 4, 2019 Author Share Posted August 4, 2019 Richard thanks for the reply . All contacts between PCB look ok i assume it must be just one of the contacts as i can get the red to illuminate. Link to post Share on other sites More sharing options...
Phil S Posted August 6, 2019 Share Posted August 6, 2019 I think the sprung contacts rely on the screws holding the chassis in place to make good contact ... certainly on the other diesel designs which used this method. Newer production gas changed to plug and socket connections ... and when i m8dify older types i replace the connections with jst micro plugs and sockets ( as now used for tender connectipns) Link to post Share on other sites More sharing options...
