Sorry to hear about this, Jeff.
Several years ago, on a tour of the Alps with Beach's Motorcycle Adventures, a special award was handed out each night at dinner. During the day, the riders nominated one person to receive the special button, based on an observed foul-up. I got mine for dropping my bike onto a grassy shoulder with the side stand placed on soft ground. The name of this prestigious award? The "Ach Scheiss!" award. I still proudly have my button.
I think you won today's!
I've got a small Brammo screw somewhere down that same Brammo rabbit hole. I figure I'll find it when it's time to change out the battery pack!
Have you tried a highly focused LED flashlight beam and a pair of hemostats?
When digging around, be careful of high voltages.
But you knew that already.
