Head light works fine. No tail or brake lites. New bulbs in each. Actually checked them to see if they worked off bike. Checked ground from brake lite fixture to fender, double-checked to see if brake handle wires were connected, checked magneto-brake lite wires, checked entire wireharness for continuity prior to assembling bike.
Still, no brake or tail lites. For a short time with the new bulb, the tail light was on when bike was running, then off. Connections appear clean. Removed bulbs again to make sure they hadn't blown out. Still intact.
So what now? Recheck wiring harness from magneto to tail light? Other?
