I can't explain the how its connected together , I'm not a mechanic whatsoever.
Perhaps the primary coil has to do something with the headlight relay/diode ?
Everything was normal , then those two issues occurred together.
With stator coil replaced , everything is good.
This is an '06 650.

I will have to look at the schematics in the service manual and see if I can figure out the connection between the two.

Sometimes things are linked together in a way you would not expect... this is interesting.

I should also add that the entire stator & coil was replaced, even though the stator tested good.
Both coil mounting screws broke upon removal. A good machinist tig welded new bolts to the broken ones to extract them . I then replaced them all with allan heads.(not that I want to go back in there). New stator claims more charging capacity then OEM.

On my dualsport bike, when I disconnect the headlight, all my indicators and turnsignals stop working, except for the highbeam indicator. Plug it back in and it's back to normal. Sometimes it's just strange.
