'06 s40, about 9,300 mi I'm 2nd(?) owner.
Lights on, clutch in, stand down, hit button, ....click. (lights go out when  start button pressed, return when released)
Check battery,  fully charged.

Since I was out on a ride, it was suggested to short across the starter solenoid. Did so and it started right up.

Possible bad solenoid, right? So, replaced it.
Rode fine two weeks then same activity.

I've looked at the wiring diagram (for an '04) and I know there is more in the ignition circuit but I'm not sure what else to check.


Suggestions?

TBH I added a short switch to the solenoid so I  could keep riding but with the season coming to a close I figured it was time to actually fix things.
