. . . but the 47 year old cloth wiring and flag terminals had to go.
Made a mistake by not replacing all of it when I rebuilt the bike. Too much resistance. This is only a 6V bike, making it worse. Many wires are internally corroded even though the jacketing looks fine.
I kept the old sheathing/conduit at least.
Bright lights and loud horn now. Hopefully better battery life too.
