Thanks Gentlemen -

Here is a picture showing the new headlight and also that wire to the frame.  Yes, as someone suggested, it's connected to the wheels, meaning, I guess, one truck has two connections to "It's" rail - the wheels come up to these "frame" wires and also the track pickup.  I WONDER WHY?  Because of poor contact - at least there are two routes?  You can see the headlight in the shot, - the Dallee guy said to try using a brass tube as a holder, I did that - I'm a little afraid that since things aren't super tight I could accidentally push the LED back into the engine meaning I'd have to take the thing apart which I loathe because these things screws strip so easily - I seem to have a stripped truck screw on this, despite it being brand new and just taking it apart ONCE.  Anyway, I guess I'll twist each pair of pickup wires together, then put them into the Dallee board and also run them to the LED at this junction.  Note RADIO SHACK is kaput, so I went to a craft store, bought some small crochet patterns of wood with holes drilled (like a breadboard) and made my own little circuit board - eat you heart out Dallee guy!

Tom   (PS I am an EE - I wonder about current loops with these two different pickups - the spring loaded skid and the wheels - but I don't know why it was designed this way.                                   Regards
