YLB Battery 10510 Power Connection to the Screw for the center Pick-up Roller.
Lionel used a black wire off-center (to the side: Do Not use) and a confusing red and black wire to a center pick-up roller. I fastened the power feed for the YLB 10510 to the Pick-up Roller screw. Make sure no excess wire touches the black screw or tender metal chassis. No soldier needs to be used. The screw should hold it.
Sincerely, John Rowlen
