chaz Posted December 30, 2018 Share Posted December 30, 2018 I have a Bachmann Conny with a front headlight that doesn't work. The decoder has been changed for a TCS WOW. The backup light works as it should, coming on when the loco reverses. I have changed the LEDs from Bachmann's original yellow ones to white ones. This hasn't corrected the fault so I need to check the wiring, plug etc. Any information as to which wires in the decoder socket and the plug-in connection between the engine and tender are for the front light would be appreciated.

chaz Posted December 30, 2018 Author Share Posted December 30, 2018 Had a thought - maybe the polarity on the LED was wrong - it should be anode (long leg) positive so red wire - and cathode black. I swapped them over but to no avail. I couldn't imagine Bachmann getting that wrong but it was worth checking. I will check the various plugs for a bent pin or misplaced wire but otherwise am baffled. I was hoping someone would know which connecting wire between the engine and tender did the front light. I suppose I might be able to trace it from the decoder plug onward.... Chaz Link to post Share on other sites More sharing options...
