mikee Posted July 21, 2022 Share Posted July 21, 2022 I am attempting to repair a partial BB set consisting x3 coaches plus Broken dummy end. How do I get the table lamps to light.? T he coaches have x6866 non pick up bogies. The lamps have redish brown and yellow wiring. For the dummy end he has given me x2 x6421 bogies which have pickups and white and green wires. I guess (I have NOT tried) I solder one wire to the yellows and one to the red/brown. BUT white to yellow or red/brown and the green to ??. The service sheet HSS379C (understandably) does not have a wiring diagram. My hornby pullman coaches have individual bogie pick ups and are quite different to the BBs. Any (helpful) suggestions folks??? Before I am tempted to get my soldering iron out. Link to comment Share on other sites More sharing options...
ColinB Posted July 21, 2022 Share Posted July 21, 2022 Well if it is the earlier version like mine power is fed to each coach by a connector on the coupling. So basically the loco picks up the power and feeds it to each coach in a cascade. Link to comment Share on other sites More sharing options...
96RAF Posted July 22, 2022 Share Posted July 22, 2022 If each coach is separate then as long as you don’t cross connect the bogies it shouldn’t matter as the lighting arrangements in each coach have a four diode bridge rectifier that allows them to light in either direction on DC or handle DCC track voltage.If each coach has a live coupling then polarity matching twixt coaches is important to avoid shorts.

Bulleidboy Posted July 22, 2022 Share Posted July 22, 2022 If I remember correctly the Brighton Belle carriage formation had to be assembled in the correct order? You say partial set - I assume you do not have a "motor bogie"? Link to comment Share on other sites More sharing options...
