Hello Everyone,

was out on a run today...all going well until i noticed no neutral light, brake light, flashers. Headlight, being fed by a different power source, is good and brightens with the revs.

Fuse- is surprisingly good. (damn) Swapped out for a factory one anyway. No difference.
Battery- is always on a tender is fine, swapped it out for one I know works for sure, no difference.
Bulbs- are good
Engine runs well and revs strong to the red line.
Rectifier- checked as the manual suggests that power flows in one way but not the other between the various wires listed

Anyone any ideas?

As you’ve stated the headlamp runs on a seperate circuit. AC directly from the stator
Everything else comes from the battery , so if this is good and can light a test lamp when connected directly , then there’s a break some where . Possibly the earth or main 6v feed from the battery seeing as nothing works. Also check for corrosion at the terminal junctions and the ignition switch.
It will be something simple and easy to find with a charged battery Then you can check if the battery is being charged etc
