I working on this engine I had to separate the upper shell from the bottom chassis to replace a broken coupler ! So while separating the two halves I found three gray wires tied together with a wire nut one of the wires comes from the pcb and another goes to the metal shell through the interior ( ground wire) ,see all pictures below . The third gray wire has a heat shrink tubing on the end that looked liked it was connected to a crimped connector. I can’t see anywhere where this has to go unless it’s part of the antenna system . Do any of you Lionel Guys now where this wire goes? Thanks in advance
