So, I called it - bad spider.
Get the issue properly reported to the NHTSA (
www.safercars.gov.). Be clear about which spider it was and also contact Yamaha. You'll see lots of detail in my original thread here:

It isn't likely to be your relay on top of the ground spider. I'd stop looking now that you've proved the point.
The real problem is that if this happened to you late at night on a dark country road you might not be here today to troubleshoot your bike.
When Yamaha wimped out with their fix I was fairly vocal about it, but they managed to convince the NHTSA that there'd been no documented cases of problems with the nacelle harness - you are probably number four on the board to have come forward with this specific problem.
I also had Harald report HIS issues on the board here:
https://www.fjrforum.com/forum/index.php?showtopic=139511. If you search the NHTSA web site for incident 10413801 you can see how he reported the problem . . . I would be very careful to stipulate that while the issue is the same, the involved components were NOT dealt with by the previous recall for what we call the 'spider bite'.
I created a number of enemies by my vocal and persistent pressure to get the original (S4) issues properly dealt with recalled, but in the end it all worked out and Yamaha may have been mad at me for having pressured them into recalling almost 10,000 bikes in North America (plus a whole bunch more everywhere else) - but that's just too darned bad. They ought to have stepped up a lot more quickly than they did.
Interesting enough, even though I was the main instigator, MY bike hasn't been done yet!! Then again I have bypassed a couple of spiders by soldering 18 gauge stranded wire to a few of the key spiders that I've run back to the battery negative, so the pressure is off. as far as my bike is concerned. You could do the same by soldering a wire to run between the spider caps on S6, S7 and S8 and tying it to battery negative. Just use one wire from a chopped up extension cord. It's quick. It's cheap and it works.
Isn't this more fun than searching for Easter eggs in your yard?
Congrats
